FIGURE 2.
AD-MSCs can be divided into CD73+ and CD73– subpopulations. (A) HE staining was used to detect the morphological changes of CD73 + and CD73– AD-MSCs. Blue arrows indicated spindle cells, red arrows showed big polygonal cells. Scale bars, 20 μm. (B) Detection of CD73 mRNA in CD73+ and CD73– AD-MSCs by Real-time quantitative PCR. Results are presented as mean ± SD.*P < 0.05, vs. CD73– AD-MSCs. (C) The expression of CD73 in CD73+ and CD73– AD-MSCs by Western blotting.
