BMP Signaling Is Activated in Border Zone Cardiomyocytes

(A) Expression traces from tomo-seq data on cryoinjured heart (3 dpi) for BMP signaling-related genes reveal peak expression in the wound border zone (indicated by dashed lines).

(B) In situ hybridizations on sham-operated and 3 and 7 dpi hearts for the BMP ligands bmp2b and bmp7, the BMP receptor bmpr1aa (alk3a), and the BMP target gene id2b. Scale bar, 100 µm.

(C) At 7 dpi, nuclear pSmad1/5/8 expression (arrow) is detected in myl7:GFP-positive cardiomyocytes at the wound border. Scale bar, 25 µm.

(D) Average percentage of cardiomyocytes at the wound border expressing nuclear pSmad1/5/8 at different time points after cryoinjury. Error bars represent SEM. Student’s t test, *p = 0.011, **p = 0.004.
