Isolation and characterization of CD73+CD39+CD146+ mesenchymal stem cell subset from bone marrow

Figure 1 Co-expression of CD73 and CD39 in bone marrow-derived mesenchymal stem cells. A: Representative flow cytometry analysis showed, as expected, 99.9% of isolated bone marrow mesenchymal stem cells were negative for CD45 (a1). Representative flow cytometry analysis showed 96.0% of CD45- population of bone marrow-derived mesenchymal stem cells were co-positive for CD73+ CD39+ (a2); B: Bar graph showing expression of CD73 and CD39 markers at passage 2 and passage 3 (n = 3). Results are mean ± SD.
