The spontaneous expression of IL-6, TGF-β and IGF-1 in MSCs.
(A) Realtime PCR was employed to detect the expression of IL-6, TGF-β and IGF-1 in MSCs. (B) ELISA assay was also used to examine the expression of IL-6, TGF-β and IGF-1 in the conditioned medium of MSCs collected at 0, 12 and 24 hours (*P < 0.05, **P < 0.01).
