Mitochondrial morphology in neonatal and adult cardiac myocytes and 3D reconstruction of mitochondria in cultured myocytes. (A) Cultured NVCMs and in vivo-transformed freshly isolated AVCMs expressing mitochondrial targeted DsRed. The two cells show significant differences in morphology as well as in mitochondrial distribution, size, and density. (B) A 3D reconstruction of mtPA-GFP PA regions (5 × 5 μm) and surrounding areas of 24- to 48-h-old myocytes transduced in vitro (Left) or in vivo (Right) at 8 min after PA.
