Morphology and flow cytometry analysis. a-b Morphology of MSC from AD, BM and CB. Scale bar, 100 μm. Morphological observation of OVCAR3, SKOV3, IGROV3 and CAOV3. Scale bar,100 μm. c-f Representative FCM result of MSC markers: CD34, CD45, HLADr, CD14, CD105, CD90, CD73, CD44, and CD24. All MSCs were positive for CD105, CD90, CD44, and CD73, and negative for the leukocyte common antigen CD45, the hematopoietic lineage marker CD34, the cancer marker CD24, and the macrophage markers HLADr and CD14 (Table 1). FCM results of CAOV3, OVCAR3, IGROV3 and SKOV3 in co-culture with MSCs and CM-MSCs. Error bars represent the means ± SD, n = 5; * p = 0.051, **p = 0.005, ***p < 0.001,****p < 0.0001
