A new simplified method of platelet-rich plasma preparation / 实用口腔医学杂志

ABSTRACT

Objective:To improve the method for isolating platelet-rich plasma (PRP). Methods:Whole blood was collected from 8 healthy donors and then PRP was separated by both the tube method and the syringe method respectively. Samples were activated to get serum rich-in growth factors (SRGF).Platelets in the SRGF were counted and the level of TGF-?1 was assayed by enzyme-linked immunosorbent assay (ELISA).Results:The end product of syringe method has both a higher platelet count in PRP (P=0.003) and a higher level of TGF-?1 in SRGF(P=0.041) than that of tube method.Conclusion:The syringe method is an effective method in preparation of PRP.
