Human san-like pacemaker cells
WebMar 31, 2009 · The SANs of rabbits have region-specific differences in cell morphology and function. 4 Cells located in the central SAN area, the leading pacemaking site, have longer action potentials, slow upstroke velocity, small amplitude, and a more positive resting membrane potential. WebSep 3, 2024 · However, human pacemaker cells, for the sake of future clinical application, are very difficult to obtain. Although it is now possible to derive SAN-like cardiomyocytes (CMs) from human pluripotent stem cells (hPSCs), the induction efficiency for nodal-like cells in current 2D cardiac-specific differentiation protocol is very low, usually at a ...
