Isolated SAN preparation and cells from neonatal and adult mouse. a Photographs of whole SAN-atrial muscle preparations dissected from neonatal (left) and adult (right) mice. CT crista terminalis, IVC inferior vena cava, RA right auricle, RV right ventricle, SVC superior vena cava. The dashed line delimits the area including SAN and the cutting edges used for intracellular potential recordings, SAN cells isolation, and qPCR. b Photographs of adult and newborn SAN cell. Scale bar 100 μm. c The membrane capacitance of SAN cells. Data are mean ± SEM
