Equine MSC inhibit bacterial growth. a CFU per ml of E. coli (left panel) and S. aureus (right panel) following culture with DMEM, DMEM with Abx, MSC or NBL6 cells. b CFU per ml of E. coli (left panel) and S. aureus (right panel) following culture with DMEM, DMEM with Abx, MSC or NBL6 cells using transwell inserts. c CFU per ml (i) and relative growth based on absorbance readings at 600 nm (ii) of E. coli (left panels) and S. aureus (right panels). Cultures were grown in DMEM, DMEM with Abx, MSC CM or NBL6 CM each diluted 1:2 in LB broth. Different letters indicate statistically significant (P < 0.05) differences.
