(a) Morphological observation (200x) of third-subculture rat BMSCs and (b) expression levels and purity of surface markers of third-subculture rat BMSCs. (a) The third-subculture cells had a long spindle-shaped morphology and were densely arranged in a swirling pattern, demonstrating the typical morphology of rat BMSCs. (b) Fluorescent-labeled CD90, CD29, CD11b, and CD45 were incubated with BMSCs, and the labeled cells were detected on a flow cytometer.
