Module 5: Figure mitochondrial Ca2+ oscillations
Mitochondrial tracking of cytosolic Ca2+ transients in hepatocytes.
Hepatocytes stimulated with phenylephrine (PE) generate repetitive Ca2+ transients (lower trace, [Ca2+]c). The Ca2+ concentration in the mitochondria (upper trace, [Ca2+]m) closely tracked the cytosolic oscillation. Reproduced from Biochim. Biophys.
