Platelet rich plasma derived from umbilical cord blood (ucPRP) was compared to adult PRP. In the written report outlined below, the ucPRP had greater ascendency than adult PRP inward damage of stalk prison theater cellular telephone proliferation together with chemotaxis (ability to accept cells migrate). Very interesting work. See abstract below.

Abstract
Platelet-rich plasma (PRP) was prepared from human adult peripheral blood together with from human umbilical cord (uc) blood together with the properties were compared inward a serial of in vitro bioassays. Quantification of growth factors inward PRP and platelet-poor plasma (PPP) fractions revealed increased levels of mitogenic growth factors PDGF-AB, PDGF-BB, together with FGF-2, the angiogenic agent VEGF together with the chemokine RANTES inward ucPRP compared to adult PRP (aPRP) together with PPP. To compare the mightiness of the diverse PRP products to cause proliferation of human os nitty-gritty (BM), rat BM together with compact os (CB)-derived mesenchymal stalk cells (MSC), cells were cultured inward serum-free media for four together with seven days amongst varying concentrations of PRP, PPP, or combinations of recombinant mitogens. It was works life that piece all forms of PRP together with PPP were to a greater extent than mitogenic than fetal bovine serum, ucPRP resulted inward significantly higher proliferation past times seven days than adult PRP together with PPP. We observed that add-on of equally petty equally 0.1% ucPRP caused greater proliferation of MSC effects than the virtually strong combination of recombinant growth factors tested, namely PDGF-AB + PDGF-BB + FGF-2, each at 10 ng/mL. Similarly, inward chemotaxis assays, ucPRP showed greater ascendency than adult PRP, PPP from either source, or indeed than combinations of either recombinant growth factors (PDGF, FGF, together with TGF-β1) or chemokines previously shown to cause chemotactic migration of MSC. Lastly, nosotros successfully demonstrated that PRP together with PPP represented a feasible option to FBS containing media for the cryo-preservation of MSC from human together with rat BM.
