Abstract
The present invention relates to a process for the preparation of porcine platelet-extract containing matured growth factors, which comprises the steps of: a) centrifuging whole porcine blood at about 1000 g to about 5000 g to isolate the platelets from the platelet-rich-plasma; b) resuspending the isolated platelets of step a) in Plasma-Lyte A and centrifuging to concentrate the platelets; c) washing the concentrated platelets of step b); d) lyophilizing the washed platelets of step c); whereby causing lysis of the platelets and producing the platelet extract in optimal amount.
