Surface marker expression of rat MSCs. Flow cytometry analysis of the immunophenotypic surface profiles for CD29, CD54, CD90, CD73, CD105, CD34, CD14, and CD45 of cultured MSCs. Histograms represent the counts of cells incubated with the relevant antibody. The logarithm on the x-axis represents the intensity of the fluorescent signal and the number of cells on the y-axis. Second passage cultured MSCs were positive for the markers CD29, CD54, CD73, CD90, and CD105 but negative for CD34, CD14, and CD45.
