Graphical representation of culture supernatant EGF (a) and TGF-β1 (b) concentrations determined by ELISA for the control, mesenchymal stem cell supernatant (MSC-Sp), and bone marrow-derived mesenchymal stem cell (BM-MSC) groups. Individual data points for all horses; bar represents the mean for each group. The concentration of TGF-β1 in the BM-MSC group was significantly higher (p = 0.0057) than the control group as indicated by the asterisk; n = 5 with two replicates per horse
