Bmp10 conditional deletion has no impact on tumor growth, angiogenesis and lung metastasis in the E0771 mammary cancer model. a Schematic representation of the experimental protocol for Bmp10 specific deletion and E0771 cells implantation. Tamoxifen was injected in all 3-week-old mice; 3 weeks later, E0771 cells were injected and tumor growth was analyzed for 3 weeks. b Plasmatic levels of BMP10 in control (CTL, n = 15) and Bmp10 conditional KO (Bmp10-cKO, n = 15) mice assessed by ELISA at the end of the experiment. c Tumor growth was assessed by caliper measurement every 2 to 3 days after tumor detection (CTL n = 7, Bmp10-cKO n = 8, 1 representative experiment out of 3). d Representative images of the tumors stained for podocalyxin (red), lectin (green) and cell nuclei (blue, Hoechst). Scale bar 50 μm. e Vascular density quantified by podocalyxin surface area (% of tumor area) and (f) Quantification of vessel perfusion by lectin staining (% area of lectin/podocalyxin) (CTL n = 7, Bmp10-cKO n = 8, 1 representative experiment out of 3). g Total area, (h) number and (i) mean size of lung metastases per mice bearing metastases (CTL n = 10, Bmp10-cKO n = 9, 2 experiments). c Data are the mean ± SEM. Statistical analysis: Two-way matched ANOVA. b, e, f, g, h, i Data are the median ± interquartile range. Statistical analysis: Mann-Whitney test. ****p ≤ 0.001 significantly different
