Cytokines and receptor expression. (A) Flow cytometry to determine PDGFs and TGF-βII receptor expression (% positivity) of BM- and LA-MSC in pHPL, tPRP and FBS. (B – D) Determination of PDGF-AA, AB, BB concentrations in six different pHPL and tPRP batches (10% supplemented medium); medium stored for 24 h (control medium) and conditioned medium by MSC (CM) via ELISA. Symbols indicate statistically significant diffences between: * stimulation; + supplements; # MSC sources; (one symbol p < 0.05; two symbols p < 0.01; n = 3 for each condition).
