Expression of BMP4 in monocytes/macrophages in the aortic roots of control (cont) and diabetic ApoE KO mice (STZ). (A) Representative images showing the localization of BMP4 (green), MOMA2 (red) and DAPI (blue) staining in each group. Frozen sections of the aortic roots were stained with anti-BMP4 and anti-MOMA2 antibodies, and were then observed under a fluorescence microscope. (B) In each group, the MOMA2-positive area (mm2) in the aortic root was measured in five separate sections from 8 mice. Results are presented as the average area. Each bar indicates mean ± S.D. **P < 0.01 vs control mice.
