Our Business We are a leader in developing and manufacturing automated blood processing systems and disposables that enable the manufacture, preservation and delivery of personalized cell and tissue therapy products, or CTT products, for clinical use. Personalized CTT products are created from the blood or tissue of a single donor and administered to that donor or a matched patient. Our systems and disposables are intended for use by hospitals and blood banks in two distinct markets. In cell therapy, our products automate the isolation, capture and preservation of stem cells residing in the blood of the placenta and umbilical cord, or cord blood, after a baby is born. These cells are used to treat patients for leukemia, lymphoma and over 60 other life threatening genetic diseases. Cord blood stem cells typically result in reduced immune complications post transplant compared to adult bone marrow stem cells. In tissue therapy, our products are used for the rapid manufacture of autologous sealants or thrombin for surgical wound care. Autologous sealants have no risk of contamination by blood-borne pathogens from other donors. We believe that our significant experience and technical expertise in developing proprietary technologies for enabling personalized CTT products, coupled with our relationships with leading transplant physicians, stem cell researchers and surgeons, has enabled us to develop safer, more effective systems for these applications. Our principal executive offices are located at 2711 Citrus Road, Rancho Cordova, California 95742. Our telephone number is (916) 858-5100. RISK FACTORS Investment in our common stock involves risk. You should carefully consider the risks we describe in our reports filed with the Securities and Exchange Commission (SEC) from time to time which are incorporated by reference herein, and those that may be set forth in any prospectus supplement, before deciding to invest. USE OF PROCEEDS Unless otherwise indicated in the applicable prospectus supplement, we expect to use the net proceeds from the sale of our common stock for working capital, to fund our future growth plans, and for other general corporate 3 purposes and capital expenditures related to our growth. We may also use a portion of the net proceeds to acquire or invest in businesses, products or technologies that complement our existing business. From time to time, we engage in preliminary discussions and negotiations with various businesses in order to explore the possibility of strategic partnering or investment. DESCRIPTION OF OUR BUSINESS BUSINESS OVERVIEW We are a leader in developing and manufacturing automated blood processing systems and disposables that enable the manufacture, preservation and delivery of personalized cell and tissue therapy products, or CTT products, for clinical use. Personalized CTT products are created from the blood or tissue of a single donor and administered to that donor or a matched patient. Our systems and disposables are intended for use by hospitals and blood banks in two distinct markets. In cell therapy, our products automate the isolation, capture and preservation of stem cells residing in the blood of the placenta and umbilical cord, or cord blood, after a baby is born. These cells are used to treat patients for leukemia, lymphoma and over 60 other life threatening genetic diseases. Cord blood stem cells typically result in reduced immune complications post transplant compared to adult bone marrow stem cells. In tissue therapy, our products are used for the rapid manufacture of autologous sealants or thrombin for surgical wound care. Autologous sealants have no risk of contamination by blood-borne pathogens from other donors. We believe that our significant experience and technical expertise in developing proprietary technologies for enabling personalized CTT products, coupled with our relationships with leading transplant physicians, stem cell researchers and surgeons, has enabled us to develop safer, more effective systems for these applications. In recent years, our revenue primarily has been generated from the sale of our BioArchive System and related disposables. However, we currently are developing and commercializing new automated systems that enable the manufacture of personalized CTT products. Our products and products in development are described below. o The BioArchive System is an automated cryogenic system used in cell therapy to cryopreserve and archive cord blood stem cells for future transplant. We have sold 117 BioArchive Systems to date to major cord blood banks and stem cell research institutes in 26 countries. We have recently signed a global distribution agreement with GE Healthcare granting them exclusive rights to distribute the BioArchive System and related disposables. o The AutoXpress, or AXP, System is our newly developed automated system and disposable intended for use in cell therapy to isolate and capture stem cells from cord blood. Our agreement with GE Healthcare also grants them exclusive rights to distribute the AXP System and disposables, and we expect sales to begin in the first quarter of 2006. o The CryoSeal Fibrin Sealant, or FS, System is an automated system used in wound care to prepare an autologous hemostatic surgical sealant from 4 a patient's own blood in approximately one hour. We have completed our pivotal 150 patient U.S. clinical trial and are preparing our PMA submission. In addition, we have received the CE Mark, and in Japan our distribution partner, Asahi Medical, filed their PMA equivalent in March 2005. o The Thrombin Processing Disposable, or TPD, is used in wound care to isolate activated thrombin from the patient's blood plasma in less than 30 minutes. Thrombin is used as a topical hemostatic agent for minor bleeding sites, to treat pseudo aneurysms and to release growth factors from platelets. We have signed non-exclusive distribution agreements with Biomet, Medtronic and Asahi Medical for sales of our TPD. BACKGROUND Industry CTT is a broad and rapidly growing field of medicine that requires the collection, purification, manipulation, storage and administration of stem cells, proteins and growth factors tailored to individual patients. Personalized CTT products are created from the blood or tissue of a single donor, administered to that donor or a matched patient, and used either for the treatment of leukemia, lymphoma and over 60 other life threatening diseases, or for surgical wound care. Critical factors in providing effective personalized CTT products are that they be precisely identified and tracked from their source to the receiving patient and that every manufacturing step, such as harvesting, processing, freezing, transporting, matching and delivering, preserves the viability and sterility of the product. Cell Therapy The human body is comprised of cells of specific tissues, such as skin, liver or blood, and stem cells that are not fully differentiated into specific tissues. Until the middle of the 1990s, researchers were familiar with two major types of stem cells, embryonic stem cells and adult stem cells. However, researchers now know that pluripotent stem cells are found in cord blood, bone marrow and other tissues of the body. Pluripotent stem cells are capable of differentiation into multiple tissues such as bone, blood, nerve and muscle. All the cells residing in blood, which are red cells, white cells and platelets, arise from a particular pluripotent stem cell called the hematopoietic stem cell. Before the discovery that there were hematopoietic stem cells in cord blood, the placenta and umbilical cord were routinely discarded as biological waste. However, these hematopoietic stem cells are harvested at no risk or pain to the donor and can be preserved in a cord blood bank for clinical use with a matched patient on short notice. Their use also results in a lower incidence of post-transplant immune complications than transplants with adult bone marrow stem cells. Hematopoietic stem cell therapy is used to: o replace diseased bone marrow with healthy, functioning bone marrow for patients with blood diseases such as aplastic anemia; 5 o replace bone marrow damaged by high-dose chemotherapy or radiation therapy used to treat patients with a variety of cancers such as leukemia and lymphoma; and o provide genetically healthy and functioning bone marrow to treat patients with genetic diseases such as sickle cell anemia. With approximately four million births per year in the United States alone, cord blood represents a large, natural resource for use in the treatment of malignant and genetic diseases. Following the first successful cord blood transplant performed in 1988, awareness of the potential therapeutic value of cord blood stem cells has increased and collection and storage has grown rapidly. We believe the number of units stored will continue to grow, due in part to the following factors: o increased awareness about the availability and benefits of preserving cord blood; o improved technology to harvest the stem cells in a sterile environment and maintain their viability for many years; o growing endorsement by the medical community; o new applications for cell therapy; and o new governmental legislation. For example, in May 2005, the House of Representatives passed the National Cord Blood Stem Cell Act, which aims to store 150,000 units of cord blood in a national registry. This Act is still awaiting passage by the Senate, and there is no certainty that it ultimately will pass and be signed into law. Separately, the Health Resources and Services Administration intends to distribute funds to qualified cord blood banks to manufacture higher quality cord blood units and develop an improved system for distributing the units to matched patients. We believe that countries outside the United States are likely to follow this lead. Wound Care Wound care products are used in a variety of surgical procedures and applications to control bleeding, close incisions, assist in tissue fixation, create a physical barrier to prevent fluid or air passage and promote healing. With the population and number of surgeries increasing and as physicians learn about new applications and safer products, this market has potential for significant growth. Wound-healing products are evaluated by their safety, effectiveness, preparation time, ease of use and cost. In addition, the components of wound care products are very important, as different materials have different associated risks and benefits. Current wound care products fall into the following general categories: topical hemostats, tissue sealants and platelet gels. Topical hemostats are used when bleeding is difficult to control with conventional methods, such as 6 suturing, stapling or placement of pads or gauze at the bleeding site. The most common type of topical hemostatic agents are thrombin-based, which are used in procedures where blood clotting must be accelerated, in order to keep the surgery site dry. In addition, thrombin can be used by itself to control minor bleeding sites but is insufficient for more persistent bleeding sites. The only thrombin that is available in the United States as a stand-alone product is Thrombin JMI(R), a thrombin derived from bovine, or cow, blood. This product is only sold in limited geographies outside of the United States. The market for thrombin is growing rapidly, with Thrombin JMI net sales totaling approximately $175 million in the full year ended December 31, 2004, and already $170 million during the nine months ended September 30, 2005. Tissue sealants, which are more powerful hemostatic agents than thrombin alone, are made of either biologic or synthetic material and are used in a variety of surgical specialties and applications. They are used to close incisions, seal and secure skin flaps, reduce adhesions and promote hemostasis. Fibrin sealants make up the majority of this sub-segment. Conventional fibrin sealants are derived from large pools of up to 10,000 units of purchased human plasma and often contain animal proteins such as bovine aprotinin. While current processes attempt to remove all viral and bacterial pathogens from conventional sealants, there have been several recent peer-reviewed journal reports of the transmission of Parvovirus B-19 to surgical patients treated with these sealants. In addition, animal proteins are a potential source of agents of transmissible bovine spongiform encephalopathy, which are resistant to any methods of pathogen inactivation available to fractionators at this time. Autologous platelet gels are made by isolating the platelets from a small amount of the patient's own blood and combining those platelets with thrombin. Thrombin causes the release of growth factors from the platelets, which then trigger wound-healing and tissue repair. Platelet gels increase the quantity and concentration of growth factors at the wound site. OUR SOLUTION We believe that the use of personalized CTT products will increase due to the growing evidence and understanding of their clinical benefits in treating disease. Our proprietary systems and disposables enable the manufacture, preservation and delivery of these personalized CTT products and have substantial advantages over other products and practices available today. Our products address a broad range of CTT applications in two primary areas: cell therapy and tissue therapy, including wound care. Cell Therapy Our BioArchive and AXP Systems and disposables are designed to ensure that the stem cells in the CTT products are successfully isolated, captured and preserved such that the cells are fully viable at time of transplant, which may be months or years after production. The BioArchive System, which can store up to 3,623 units of cord blood stem cells, is the only fully automated system that 7 integrates controlled rate freezing, quarantine and long term cryogenic storage. The robotic storage and retrieval of these stem cell units improves cell viability, provides precise inventory management and minimizes the possibility of human error. To date we have sold 117 BioArchive Systems to major cord blood stem cell banks and stem cell research centers in 26 countries. Cord blood stem cell units have been used to treat leukemia, lymphoma and over 60 other life threatening genetic diseases. More recently, we have developed the AXP System, which automates the isolation and capture of hematopoietic stem cells from cord blood into a fixed 20 ml volume. It includes a compact battery powered device and a proprietary sterile disposable bag set. The AXP replaces the current clinical process, which involves more than a dozen manual steps. The AXP System will provide cord blood banks with a reproducible and GMP-compliant solution to more successfully isolate and capture stem cells with lower labor costs and reduced contamination. We expect sales of the AXP System and disposables to begin in the first quarter of 2006 through our distribution partner, GE Healthcare. Wound Care In the tissue therapy market, we have developed the CryoSeal FS System and the TPD. The CryoSeal FS System manufactures fibrin sealant in a closed and sterile disposable from a single unit of the patient's own plasma in about an hour. In contrast, conventional fibrin sealants are sourced from large pools of up to 10,000 or more units of purchased plasma and often include bovine proteins, and thus remain vulnerable to contamination by infectious pathogens residing anywhere in these sources. Our CryoSeal FS System prepares the two interactive liquid components of a fibrin sealant: (1) the wound healing proteins of fibrinogen, fibronectin, Factor VIII, von Willebrands Factor and Factor XIII and (2) the activating enzyme, thrombin. When combined at the bleeding wound site, the two components form an adhesive gel that stops bleeding and bonds tissue. Once prepared, the CryoSeal fibrin sealant may be stored frozen for up to a year or used immediately as a hemostatic agent for patients undergoing surgery. Our pivotal trial, completed in July 2005, was a 150 patient blinded, randomized multi-center clinical trial comparing the performance of CryoSeal FS to Johnson & Johnson's Instat(R) collagen sponge. The study demonstrated that patients treated with CryoSeal FS showed statistically significant reduced time to hemostasis versus the Instat(R) control group, with p=<0.001. We are currently preparing our PMA for the CryoSeal FS System for submission in the first quarter of 2006. We have received the CE Mark, allowing sales of the CryoSeal FS System in Europe, although sales into individual countries under cost reimbursement structures often requires the existence of supporting clinical usage within that country. We have, through our distribution partners in Europe, undertaken several clinical studies and, upon completion, will initiate more aggressive marketing. In Japan, our distributor, Asahi Medical, has completed enrollment in their pivotal clinical trial and filed their PMA equivalent in March 2005. In addition, several field trials are underway in other geographies to provide a cost justification for reimbursement for use of the product. 8 The TPD is incorporated in the CryoSeal FS system but can be sold as a stand alone product. It is a disposable device that isolates and captures activated autologous thrombin from approximately 11 ml of patient blood plasma. Thrombin is used as a topical hemostatic agent for minor bleeding sites, to treat pseudo aneurysms and to release growth factors from platelets. We have a received the CE Mark for TPD and began selling the product in Europe through our distributor in August 2005. The TPD standalone product would require a separate PMA before sale in the United States. OUR STRATEGY We believe our products significantly enhance the safety and viability of CTT products and will ultimately expand the use and success of CTT products in clinical treatment. Our strategy is to expand our leadership position in the area of medical devices and disposables for the manufacture and preservation of personalized CTT products. The key elements of our strategy include: o Begin commercializing the AXP system through our strategic partner, GE Healthcare Complete the PMA and receive approval for our CryoSeal FS System in the United States and Japan o Expand commercialization of the TPD through Biomet, Medtronic, Asahi Medical and potentially other distribution partners o Expand our reach through both sales and consulting services for clinical trials o Accelerate our research and development efforts o Leverage our installed base to generate additional recurring revenue CORPORATE INFORMATION We are incorporated in Delaware.

As of November 18, 2005, there were 45,981,192 shares of common stock and no shares of preferred stock outstanding. Holders of shares of common stock have full voting rights, one vote for each share held of record. Stockholders are entitled to receive dividends as may be declared by the Board out of funds legally available therefore and share pro rata in any distributions to stockholders upon liquidation. Stockholders have no conversion, preemptive or subscription rights. All outstanding shares of common stock are fully paid and nonassessable, and all the shares of common stock issued by us upon the exercise of outstanding warrants will, when issued, be fully paid and nonassessable. 9 PLAN OF DISTRIBUTION We may sell all or a portion of the common stock: o Through one or more underwriters or dealers for public offering and sale; o Directly to investors; o Through agents; o Through a block trade in which the broker or dealer engaged to handle the block trade will attempt to sell the common stock as agent, but may position and resell a portion of the block as principal to facilitate the transaction. We may distribute the common stock from time to time in one or more transactions at a fixed price or prices, which may be changed from time to time: o at market prices prevailing at the time of sale, or o at negotiated prices. We will describe the method of distribution of the common stock in the prospectus supplement. Underwriters, dealers or agents may receive compensation in the form of discounts, concessions or commissions from us or the purchasers, as their agents, in connection with the sale of the common stock. These underwriters, dealers or agents may be considered to be underwriters under the Securities Act of 1933, as amended, and, therefore, any discounts, commissions, or profits on resale received by such underwriters may be treated as underwriting discounts and commissions. In the prospectus supplement, we will identify any such underwriter, dealer or agent, and describe the compensation received by them from us. Any public offering price and any discounts or concessions allowed or reallowed or paid to dealers may be changed from time to time. Underwriters, dealers and agents may be entitled to indemnification by us against certain civil liabilities, including liabilities under federal securities laws.

Such person may not be indemnified if the person has been adjudged liable to the corporation in the performance of such person's duties to the corporation, unless the Court of Chancery or the court in which such action or suit was brought determines that, in view of the circumstances of the case, such person is fairly and reasonably entitled to indemnity. To the extent that such person has been successful on the merits or 12 otherwise in defense of any proceeding, the General Corporate Law of the State of Delaware provides that such person shall be indemnified against expenses (including attorney's fees) reasonably and actually incurred. The Certificate of Incorporation and the By-laws of the Company provide for indemnification of directors and officers to the fullest extent permitted by the General Corporation Law of the State of Delaware. The General Corporation Law of the State of Delaware provides that a certificate of incorporation may contain a provision eliminating the personal liability of a director to the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director provided that such provision shall not eliminate or limit the liability of a director (i) for any breach of the director's duty of loyalty to the corporation or its stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) for unlawful payment of dividends or stock redemption, or (iv) for any transaction from which the director derived an improper personal benefit. The Company's Certificate of Incorporation contains such a provision. We have indemnification agreements with our officers and directors to indemnify and provide advanced legal expenses as permitted by applicable law, our Certificate of Incorporation and Bylaws. Under the agreements, we will not indemnify or provide advance payments (i) for a violation of Section 16 of the Securities Exchange Act, (ii) in connection with an officer's or director's takeover attempt, or (iii) any other action where indemnification is not permitted by law. The agreement terminates when the officer or director leaves or is removed from his position. Item 16. Exhibits Exhibit No. Description ----------- ----------- 5.1 Opinion of Bullivant/Houser/Bailey P.C. 23.1 Consent of Ernst & Young, LLP 23.2 Consent of Bullivant/Houser/Bailey P.C. (contained in Exhibit 5.1) Item 17. Undertakings (a) The undersigned registrant hereby undertakes (1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement: (i) To include any prospectus required by section 10(a)(3) of the Securities Act of 1933; (ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the 13 aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective registration statement; (iii) To include any material information with respect to the plan of distribution not previously disclosed in this registration statement or any material change to such information in the registration statement. (2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering. (4) That, for the purpose of determining liability under the Securities Act of 1933 to any purchaser: (A) Each prospectus filed by the registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and (B) Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5), or (b)(7)(2), (b)(5), or (b)(7) of this chapter) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii), or (x) (i), (vii), or (x) of this chapter) for the purpose of providing the information required by section 10(a) of the Securities Act of 1933 shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which that prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Provided, however, that no statement made in registration 14 statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date. (5) That, for the purpose of determining liability of the registrant under the Securities Act of 1933 to any purchaser in the initial distribution of the securities: The undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser: (i) Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424 (ss.230.424 of this chapter); (ii) Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant; (iii) The portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and (iv) Any other communication that is an offer in the offering made by the undersigned registrant to the purchaser. * * * * * (b) The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant's annual report pursuant to section 13(a) or section 15(d) of the Securities Exchange of 1934 Act that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered herein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. * * * * * (c) The undersigned registrant hereby undertakes to deliver or cause to be delivered with the prospectus, to each person to whom the prospectus is sent or given, the latest annual report to security holders that is incorporated by 15 reference in the prospectus and furnished pursuant to and meeting the requirements of Rule 14a-3 or Rule 14c-3 under the Securities Exchange Act of 1934; and, where interim financial information required to be presented by Article 3 of Regulation S-X are not set forth in the prospectus, to deliver, or cause to be delivered to each person to whom the prospectus is sent or given, the latest quarterly report that is specifically incorporated by reference in the prospectus to provide such interim financial information. * * * * * (d) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue. (e) The undersigned registrant hereby undertakes that: (1) For purposes of determining any liability under the Securities Act of 1933, the information omitted from the form of prospectus filed as part of this registration statement in reliance upon Rule 430A and contained in a form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities Act shall be deemed to be part of this registration statement as of the time it was declared effective. (2) For the purposes of determining any liability under the Securities Act of 1933, each post-effective amendment that contains a form of prospectus shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. 16 SIGNATURES Pursuant to the requirements of the Securities Act of 1933, the registrant certifies that it has reasonable grounds to believe that it meets all of the requirements for filing this Form S-3 and duly caused this registration statement to be signed on its behalf by the undersigned, thereunto duly authorized, in Rancho Cordova, California, on November 18, 2005.
