This patent grant further adds to the Company's increasing technology base covering a variety of cell preservation methods. The two major recipient groups for blood platelets are cancer patients that have undergone chemotherapy and/or radiation treatment (about 70%), and trauma patients suffering from extensive bleeding. "This new patent covers the process of cooling blood platelets to near zero degrees Centigrade to keep them fresh and preserved for greater than the current standard of 5 days. We anticipate being able to extend this process to 7 days and beyond. This will reduce the current need to discard stored platelets that have been preserved by existing methods," explained Dr. David Winter, President of Human BioSystems. Current technology provides for the storage of platelets at room temperature. This allows any bacteria present to grow rapidly over the current 5-day allowable shelf period. "By developing a cooling method that prolongs the preservation of platelets, we greatly reduce the risk of bacterial infection while increasing the availability of essential medical resources required to treat cancer and trauma patients," Dr. Winter stated. Human BioSystems is a developer of preservation platforms for organs and other biomaterials. The Company, which is headquartered in Palo Alto, California with research facilities in Michigan, has made tremendous progress in its nine-year history. This fourth patent is another milestone for Human BioSystems. The Company is also currently conducting tests with two independent and FDA approved laboratories on its proprietary preservation methods.
