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

Figure 2

Comparison of the platelet concentration procedure between t-PRP and c-PRP. (a) Photographs showing the preparation and activation process of PRP between t-PRP and c-PRP. Whole blood (left), whole blood after the first centrifugation (middle), and plasma after the second centrifugation (right). Compared to c-PRP, the t-PRP group more clearly shows the boundary between red blood cells and plasma and the absence of red blood cell contamination in the plasma and PRP. (b) After activation, t-PRP completely gelled in about 15 min and began to precipitate plasma until 30 min. The arrow indicates the t-PRP group. (c) The relative concentration of platelets to whole blood between t-PRP and c-PRP groups. t-PRP showed significantly higher platelet counts than c-PRP. (d) Hematology analysis showed that, compared with whole blood (left) and c-PRP (middle), t-PRP (right) had a marked decrease in red blood cells and leukocytes while remaining unchanged in platelet distribution width and peak. ; .
