Effects of adipose stem cell (ASC)-secreted vascular epithelial growth factor (VEGF)-A and fibroblast growth factor (FGF)-2 on chondrocytes. (A) Schematic outlining chondrocytes treated with ASC-conditioned medium with VEGF-A and FGF-2 neutralizing antibodies and assayed for (B) [35S]-sulfate incorporation, (C) caspase-3 activity, and (D) [3H]-thymidine incorporation after 24 hours of treatment (n = 6 ± SE). *P < 0.05 vs. control; #P < 0.05 vs. ASCs.
