Figure Lengend Snippet: Identification of binding effect of BMP-2 and BMP-9 to BMPR2 in MC3T3-E1 cells by Noggin. ( A ) BMP-2–treated group, ( B ) BMP-2 + Noggin–treated group, ( C ) BMP-9–treated group, ( D ) BMP-9 + Noggin–treated group. DAPI (blue), anti-BMPR2 (red), and anti-BMP-2 or anti-BMP-9 (green). Merged images show co-localization (yellow). Scale bar: 10 μm; magnification: ×600. ( E ) Western blot of SMAD1/5/9 phosphorylation under the indicated treatments. Top, p-SMAD1/5/9; middle, total SMAD1/5/9; bottom, GAPDH. ( F) Alkaline phosphatase (ALP) activity measured 60 min after BMP addition using a p-nitrophenyl phosphate colorimetric assay (405 nm). Bars indicate mean ± SD ( n ≥ 3). p < 0.0001 vs. NT for all treated groups; asterisks denote significance relative to NT.
