Fig. 4From: A transcriptomic analysis of serial-cultured, tonsil-derived mesenchymal stem cells reveals decreased integrin α3 protein as a potential biomarker of senescent cellsChanges in expression of stem cell surface markers in TMSCs with serial passaging. Surface markers of TMSCs were characterized using FACS analysis. Both hematopoietic (CD14, CD34, and CD45) and primitive (CD90, CD73, and CD105) cell surface markers were analyzed. Control- and culture-aged TMSCs were marked as red and blue lines, respectivelyBack to article page
