ThermoGenesis Announces Filing of 510(k) Application for MarrowXpress

RANCHO CORDOVA, Calif., June 4 /PRNewswire-FirstCall/ -- ThermoGenesis Corp. (Nasdaq: KOOL), a leading supplier of innovative products and services that process and store adult stem cells, today announced that it has submitted a 510(k) pre-market notification application to the FDA requesting regulatory clearance for its MarrowXpress(TM) (MXP(TM)), a device designed for the processing of bone marrow in a laboratory setting.

The device is a derivative of the Company's approved AutoXpress(TM) (AXP(TM)) Platform that is used to volume reduce and collect stem cells from umbilical cord blood.

"This is an important milestone in the Company's product diversification and growth strategy. We are hopeful that the regulatory process will be facilitated because the MXP is based on a currently approved device," said Dr. William Osgood, Chief Executive Officer.

Osgood said the Company expects to receive a CE Mark for the MXP this month, which would enable the Company to begin commercial marketing of the device in Europe.

"The use of adult stem cells to treat a variety of diseases and injuries is very promising. There are a number of clinical trials already underway, and in several countries it is a practice of medicine for indications such as critical limb ischemia, coronary artery disease and orthopedic conditions. We have had very encouraging discussions with leading research centers in both the U.S. and Europe regarding the potential use of the MXP in ongoing clinical trials and look forward to getting this device into the clinical setting. We believe this could ultimately represent a multi-billion dollar market opportunity for the Company," he added.
