A Novel and Convenient Method for the Preparation and Activation of PRP without Any Additives: Temperature Controlled PRP

Figure 3

Histologic observations between t-PRP and c-PRP. (a) Masson staining of both c-PRP and t-PRP gels. The c-PRP gel showed a more tightly compressed fibrin network and more uneven platelet aggregation than t-PRP. Scale bars = 100 μm. (b) SEM analysis of the PRP gel showed that the fibrin networks in the c-PRP gel were constituted by the thick and tightly packed fibrin polymers, while the t-PRP gel was looser and uniformly distributed. Scale bars = 20 μm. Magnification SEM view showed that the platelets were trapped in the fibrin mesh. (c) TEM analysis showed that platelets from both groups were activated and degranulated. Scale bars = 50 nm.
