(A) Mitochondrial mass markers (mitotracker) were used to label exogenous internalized (green) and endogenous mitochondria (red). (B) Both mitotracker signals were plotted, each dot representing a single cell. The mitochondrial mass appeared to be distributed according to two distinct clusters that could be arbitrarily...
