Exhibit 99

THERMOGENESIS CORP. APPOINTS INDUSTRY VETERAN WILLIAM OSGOOD
AS GENERAL MANAGER OF OPERATIONS

RANCHO CORDOVA, CA. (January 3, 2007) – ThermoGenesis Corp. (Nasdaq: KOOL), a company that designs and develops enabling technologies for stem cell therapy and surgical wound care, has appointed William Osgood, Ph.D., MBA as General Manager, Operations, effective January 1, 2007. Mr. Osgood will report directly to Philip H. Coelho, ThermoGenesis’ Chairman and Chief Executive Officer.

“Bill brings more than 20 years of leadership experience in the operations of Class II and III medical device companies to ThermoGenesis, making him ideally suited to help lead the company during our transformation into a high-growth commercial organization with an expanding presence in the cell therapy and surgical wound care markets,” Mr. Coelho stated. “Bill is an experienced, energetic, articulate and decisive leader with the management skills that breed good morale and high productivity in the employees. In the near-term, Bill’s focus will be to engage the vendors who manufacture our Cell Therapy disposables to improve our quality assurance as we ramp up production of our AutoXpress™ cord blood stem cell processing system. In addition, Bill will work with other senior members of the leadership team to complete the CryoSeal^® U.S. regulatory filing, implement ‘lean’ high quality manufacturing and establish a flexible, and responsive operation.”

Mr. Osgood previously served as Senior Vice President of Sorin Group Company’s $250 million cardiopulmonary business, where he managed worldwide commercial operations and research and development for its intra-operative heart and lung devices and related disposables. Mr. Osgood joined Sorin after the company acquired COBE Cardiovascular Inc., where he led the industrial integration of plants worldwide. Prior to this, Mr. Osgood was Vice President of Baxter Healthcare’s $800 million CardioVascular Group, where he successfully reengineered business processes across multiple divisions resulting in sales growth, cost reductions and deeper customer partnerships.

Mr. Osgood stated, “I am enthusiastic about joining ThermoGenesis at this exciting time in the Company’s evolution. The Company’s cell processing technology already helps cord blood stem cell banks improve efficiency and cell viability, while its surgical wound care products offer surgeons sealants and thrombin derived from a patient’s own blood, eliminating viral or prion risks associated with alternative products derived from “pools” of human or bovine blood or tissue. I look forward to implementing quality control standards necessary to support ThermoGenesis’ broad penetration of its two key markets with world-class commercial and manufacturing operations.”
