BrdU+ myocytes during the first week of life: Representative confocal images (A, B) of 7 day old WT (n = 148, N = 3) and α1G−/− (n = 137, N = 3) hearts. BrdU is in green, DAPI is in blue and cardiac α-actin is in red. Merged images are shown. Average data is shown in C. There were significantly fewer BrdU+ myocyte nuclei in α1G−/− hearts. *p < 0.005, n: # of myocytes, N: # of hearts.
