Relative growth of S. aureus after 1, 2 and 3 h of incubation in CM and CCM from bovine fetal FB, BM-MSC and AT-MSC. A S. aureus relative growth was lower (P < 0.05) in CM from FB, BM-MSC, and AT-MSC compared to relative growth in DMEM (positive control). B S. aureus relative growth after 1, 2 and 3 h of culture was lower (P < 0.05) in CCM from BM-MSC and AT-MSC compared to growth in concentrated DMEM and CCM from FB, respectively. (a, b) Indicate significant (P < 0.05) difference between cell type and DMEM. DMEM: Dulbecco’s Modified Eagle Medium; FB: fibroblasts, BM-MSC: bone marrow-derived mesenchymal stem cells; AT-MSC: adipose tissue-derived mesenchymal stem cells; CM: conditioned media; CCM: concentrated conditioned media.
