New Performance Data Presented at ISCT Demonstrates ThermoGenesis' AutoXpress(TM) System (AXP) Efficiently Separates Stem Cells From Cord Blood

ThermoGenesis' AXP and BioArchive(R) Systems Attain High Quality Standard for Processing Stem Cells from Cord Blood

RANCHO CORDOVA, Calif., May 8 (HSMN NewsFeed) -- ThermoGenesis Corp. (Nasdaq: KOOL ) today announced that new performance data related to the Company's AXP, the first automated, functionally-closed, sterile system that harvests stem cells from cord blood with high yield and high throughput was presented at the International Society for Cellular Therapy (ISCT) Annual Meeting which took place from May 4 to 7 in Berlin, Germany. The results, compiled at the New York Blood Center's National Cord blood Program, showed that the AXP can harvest 97% of the mononuclear cell (MNC) population (which contain all the stem cells) from cord blood consistently and efficiently. When these cell populations are frozen and archived in the BioArchive System, the cell viabilities exceed 94% after thawing.

"Cord blood processing labs must use efficient and reliable methods for processing, cryopreserving, freezing and storing cord blood to maximize recovery and viability of hematopoietic stem and progenitor cells for bone marrow transplantation. These cells are critical to patients who require stem cell reconstitution in the treatment of diseases like acute leukemia, lymphoma and numerous genetic diseases" according to the presenting investigator of the study, John Chapman, Ph.D. Vice President of Scientific Affairs of ThermoGenesis Corp.

The AXP is designed to bring automation and precision to cord blood stem cell processing, which is usually performed in a labor intensive manual process that often requires an expensive "clean room". Cord blood is collected from umbilical cords in volumes of up to 170ml and essentially all the mononuclear cells should be concentrated into a consistent 20 ml volume prior to addition of the cryoprotectant.

In October 2005, GE Healthcare acquired the exclusive global distribution rights for the AXP from ThermoGenesis, as well as non-excusive distribution rights for the BioArchive System. The company estimates that approximately 200 cord blood banks are operating in 44 countries and processing several hundred thousand cord blood units annually.

About ThermoGenesis Corp.

ThermoGenesis Corp. is a leader in developing and manufacturing automated blood processing systems and disposable products that enable the manufacture, preservation and delivery of cell and tissue therapy products. These products include:

-- The BioArchive® System, an automated cryogenic device, is used by cord blood stem cell banks in more than 25 countries for cryopreserving and archiving cord blood stem cell units for transplant. GE Healthcare is the non-exclusive global distribution partner for the BioArchive System.

-- The AutoXpress(TM) System, is a newly developed semi-automated device and companion sterile closed blood processing disposable, to harvest stem cells from cord blood. GE Healthcare is the exclusive global distribution partner for the AXP AutoXpress(TM) System.

-- The CryoSeal® FS System, an automated device and companion sterile blood processing disposable, is used to prepare fibrin sealants from plasma in about an hour. Enrollment in a 150-patient U.S. pivotal clinical trial has been completed and a PMA is being reviewed by the FDA. The CryoSeal FS System has received the CE-Mark. From a marketing perspective, the CE Mark is the European equivalent to an FDA approval, in that it allows sales of the product throughout the European community.

-- The Thrombin Processing Device(TM) (TPD(TM)) is a sterile blood processing disposable that prepares activated thrombin from a small aliquot of plasma in less than 30 minutes. The CE-Marked TPD is currently being marketed in Europe by Biomet, Inc. subsidiary of Biomet Biologicals, Medtronic, Inc. and independent distributors.
