Effects of PRP on stem cell proliferation, differentiation potential and bone healing. (A) Effect of different PRP concentrations on the proliferation of bone-marrow derived MSCs [41]. (B) Three-dimensional micro-CT of a bone defect implanted with hydrogels containing either PBS or PRP [84]. (C) Differentiation media supplemented with PRP, bone marrow and adipose derived MSCs exhibit strong differentiation potential towards osteogenic (Alizarin Red S, calcium deposits) and chondrogenic (Toluidine Blue, glycosaminoglycans), but not adipogenic (Oil Red O, lipid accumulation).
