Total and relative collagen I synthesis normalized to the negative control. a The total collagen I synthesis was significantly increased in the PRP group and the positive control compared to the negative control. PRP treatment led to significantly elevated effects in the hTLCs of the older compared to the younger donors. b Collagen I synthesis relative to cell proliferation was significantly reduced in the PRP group compared to the positive and negative controls, as well as in the positive compared to the negative control. In the younger male donors, the relative collagen I synthesis was significantly reduced compared to the older male and younger female groups. Stars indicate significant differences at p ≤ 0.05 between groups
