Additional file 5: of Stemness marker ALDH1A1 promotes tumor angiogenesis via retinoic acid/HIF-1Îą/VEGF signalling in MCF-7 breast cancer cells

Figure S3. Ki67 index is associated with ALDH1A1 expression in mice tumors. Representative images of immunostaining for Ki67. The number of immunoreactive cells was estimated semi-quantitatively. Tumors ALDH1A1+ and Scr had greater 70 % of positive cells and were scored as +++. Tumors ALDH1A1KD had 10-30 % of positive cells and were scored as +. Magnification 20x. Scale bar, 50 Îźm.
