Isolation and identification of ADMSCs. A, flow-cytometric analysis of rat ADMSCs. ADMSCs were incubated with FITC-conjugated antibodies. Primary rat ADMSCs positively expressed MSC specific markers CD29 (+), CD44 (+), CD90 (+), but negatively expressed hematopoietic stem cell markers including CD34 (−) and CD45 (−). B, rat ADMSCs are spindle-shaped after ten days in culture.
