Identification of MSCs and MNC-QQs. (A) Representative images of MSCs. (B) The expressions of surface marker on MSCs were analyzed by flowcytometry. The expressions of CD105, CD90, and CD73 were positive and HLA-DR, CD34, CD14, and CD45 were negative in MSCs (blue). Red lines indicate isotype control. (C) The expression of CD34, CD206, CCR2, CD14, CD3, CXCR4, CD19, and CD56 in MNC-QQs were analyzed by flowcytometry. MSC, mesenchymal stem cell; MNC-QQs, quality and quantity cultured peripheral blood MNCs.
