FIGURE 1. Maternal type 2 diabetes mellitus induces heart defects and oxidative stress in developing heart.
A, Morphological structures of E17.5 embryonic hearts. B, Representative images of dihydroethidium staining of E12.5 embryonic hearts. Cell nuclei were stained with 4′,6-diamidino-2-phenylindole (blue). Scale bar = 30 μm. C, Lipid peroxidation levels in E12.5 embryonic hearts. Experiments were performed using 3 embryonic hearts from 3 different dams per group. D, E17.5 heart and blood vessels imaged in whole mount after injection of India ink.
*Significant differences (P < .05) compared with other groups.
