London, June 24 : US scientists have come up with an idea of freeze-drying blood platelets to make them release human growth factors, small blood cells that trigger the formation of a new layer of skin to help repair wounds.

Lead researcher Fern Tablin says that her technique involves removing plasma from blood, and washing away all other blood cells to leave only the platelets.

According to her, the platelets are added to polymers and a sugar before being freeze-dried.

She says that the powder would then be feasible to be applied to wounds directly or impregnated into bandages.

The researcher says that such a dressing may help stimulate healing when applied to a wound, reports New Scientist magazine.
