Allogeneic Platelet Releasate Preparations Derived via a Novel Rapid Thrombin Activation Process Promote Rapid Growth and Increased BMP-2 and BMP-4 Expression in Human Adipose-Derived Stem Cells

The effects of tPR on the growth of passage 0 ASCs. 100,000 freshly isolated SVF cells were plated and grown for ten days in either 10% FBS or 10% PR. (a) tPR treated cells yielded over four times as many cells after ten days in culture . (b) Various ASC lines at P0 (A1–A5) were treated with different tPR preps (P1–P4) to determine the variability different cell lines and tPR preps would have on cell growth. The variability seen in the P0 yields appears to be attributable to differences in the adipose tissue samples.
