Fig. 4: Immunoregulatory potential of the CMKLR1+ MSC functional subpopulation.

a The proliferative ability of CMKLR1+ MSCs was weaker than that of CMKLR1− MSCs. b PCR results showed that CCL2, TGF-β, IGFBP2, PTX3, GREM1, and CTGF expression levels were higher in CMKLR1+ MSCs than in CMKLR1− MSCs. c The immunoregulatory ability of CMKLR1+ MSCs determined by CFSE-based flow cytometry assays was stronger than that of CMKLR1− MSCs. d The immunoregulatory ability of MSCs determined by CFSE-based flow cytometry assays was positively related to the percentage of CMKLR1+ MSCs.
