Relative growth of S. aureus after 1, 2 and 3 h of incubation in CM, ACM and CACM from bovine fetal FB, BM-MSC and AT-MSC. A S. aureus relative growth was lower (P < 0.05) in ACM from BM-MSC and AT-MSC compared to S. aureus growth in DMEM, CM from FB, ACM from FB, CM from BM-MSC and CM from AT-MSC. B S. aureus relative growth was reduced (P < 0.05) in CACM from BM-MSC and AT-MSC compared to growth in DMEM, CCM from FB, CACM from FB, and CCM from BM-MSC, CCM from AT-MSC. (a–c) 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; ACM: activated conditioned media; CACM: concentrated activated conditioned media.
