Abstract:
1. A process for preparing platelet rich plasma to obtain growth factors for use in wound healing comprising: providing platelets selected from one of a pooled and a single donor platelet source; concentrating said platelets into a platelet rich plasma; discarding platelet poor plasma from said platelet rich plasma following concentration of said platelet rich plasma; adding fresh plasma into said platelet rich plasma; mixing said platelet rich plasma with said fresh plasma to provide a platelet rich plasma mixture; starting lyophilization of said platelet rich plasma mixture immediately following mixing while said platelet rich plasma mixture is still in liquid form to nonchemically release growth factors from said platelet rich plasma under lyophilization conditions that do not activate the platelets; and continuing lyophilization until a freeze-dried composition results.
