Confocal image taken from a frontal section of a day 14 rabbit embryo heart; the ventricular apex is shown. The section is a 12-μm thick stacked confocal series labeled for Connexin 43 (Cx43) (green), sarcomeric actin (red), and vimentin (blue). Cx43 is found primarily between sarcomeric actin-positive cells, the cardiomyocytes.
