Also, thin cross sections of ventricular cells revealed pleomorphic mitochondria with partially disrupted cristae, partial disruption of the myofibrils and deposited toxic materials.
In further experiments with the flies, the research team found that ATP synthase was essential to normal stem cell development, directly controlling the growth and maintenance of the inner membranes inside mitochondria, called cristae, as the cells continue to divide and form the specific cell components that make up an egg, or female germ cell.
After the three-month treatment, the researchers looked at changes in mitochondria volume and the abundance of cristae, which are internal compartments of mitochondria that are necessary for efficient function of the mitochondria, and measurable by electron microscopy.
proximal, middle and distal at 10th DAA depicted the presence of more anastomosing mitochondrial cristae in the bold grains as compared to the small grains (Figure 3).
