Relative gene expression measured by qRT-PCR and normalized to GAPDH and the negative control (line). Stars above brackets mark significant differences between these groups at p ≤ 0.05. Stars alone mark significant differences to the negative control. a Collagen I expression was significantly reduced in all the investigated groups except the older male group compared to the positive control. b The expression of collagen III was significantly increased in the PRP-treated cells compared to the positive and/or negative control in all the groups except the older males. c No significant differences were demonstrated for the osteocalcin expression
