Characterization of mitochondrial populations during stem cell differentiation.

Mitochondrial dynamics play an important role in numerous physiological and pathophysiological phenomena in the developing and adult human heart. Alterations in structural aspects of cellular mitochondrial composition as a function of changes in physiology can easily be visualized using fluorescence microscopy. Commonly, mitochondrial location, number, and morphology are reported qualitatively due to the lack of automated and user-friendly computer-based analysis tools.
