IL-6 and PGE2 secretion by primed MSC. a Scheme of MSC treatment with CM or cytokines. b IL-6 and PGE2 levels in media of MSC primed or not (−) with CMGM or CMM. CM were incubated or not (−Ab) with neutralizing antibody (Ab) against TNF-α or IL-10. c IL-6 and PGE2 levels in media of MSC primed or not with the indicated doses of TNF-α, IL-10 or combinations of both cytokines. *p < 0.05
