Electrically Induced Calcium Handling in Cardiac Progenitor Cells

Figure 2

Nuclear Ca²⁺ increases more than cytosolic Ca²⁺ in response to electrical stimulation. Fluo-4/AM-loaded hcCPCs were stimulated at 0.5 Hz and the amplitudes of the nuclear and cytosolic Ca²⁺ oscillations were analyzed. Representative traces of nuclear (red) and cytosolic (blue) Ca²⁺ oscillations are shown in (a), and amplitudes are summarized in (b). Data represent mean ± SD. ; Student’s -test. cells from 4 different pools of cells for all points.
