Platelet-rich plasma does not change adipose-derived stem cell marker expression but changes chondrocyte-related gene expression. The expression of CD14, CD34, CD44, CD45, CD73, and CD90 was changed in the (A) 10% platelet-rich plasma (PRP10), (B) 15% PRP (PRP15), and (C) 20% PRP (PRP20) groups compared with the 10% fetal bovine serum (FBS10) group (Figure 1). (D) Expression of collagen type II (COL-II), Sox9, and aggrecan was strongly promoted in the PRP10, PRP15, and PRP20 groups compared with that in the FBS10 group.
