Ratio of Bmp+ (E) and Brachyury+ (F) cells in spheroids from (D). Data are shown as mean ± SEM. Each dot represents an individual spheroid. In (E), n = 99 (FAX) and 75 (FAXN) spheroids. In (F), n = 38 (FAX) and 47 (FAXN) spheroids. 3 independent experiments. Mann-Whitney U test.*p = 0.0153,****p < 0.0001.
