As one approach, we have reported that mice lacking Cx45 conditionally in cardiac myocytes display a similar lethal phenotype to that of germline Cx45 в€’/в€’ mice (Nishii et al., 2003). In addition, these structures are indirectly connected by a growth factor network (Nishii et al., 2001).ДЄn experimental system that would enable analysis of the specific cardiac muscular function of Cx45 is therefore needed. Impaired cardiac function should have a vicious effect on normal development of the vascular system, as the cardiovascular system constitutes a closed circuit. However, other abnormalities related to endocardial cushion formation and vascular development have also been described (KrГјger et al., 2000 Kumai et al., 2000). Cx45 в€’/в€’ mice display conduction block in primitive cardiac myocytes (Kumai et al., 2000). In early cardiogenesis, Cx45 seems the only active connexin in the myocardium. Following this downregulation, Cx45 remains expressed at high levels in the cardiac conduction system (Coppen et al., 1999). It is expressed in almost all tissues during early embryogenesis, and then it undergoes consistent downregulation (AlcolГ©a et al., 1999 Kumai et al., 2000). It has unique characteristics of low unitary conductance, strong voltage dependence, selective permeability, and pH sensitivity (Veenstra et al., 1994 Elfgang et al., 1995 Hermans et al., 1995 Moreno et al., 1995 Steiner and Ebihara, 1996 Barrio et al., 1997 Peracchia et al., 2003). Cx45 is one of the three gap junction proteins in mammalian cardiac myocytes (Lo, 2000). Various configurations of the gap junction may be related to functional differences among species. There are many forms of gap junction structures among vertebrate cardiac myocytes (Shibata and Yamamoto, 1979).

Our results indicate that Cx45 is an essential connexin for coordinated conduction through early cardiac myocytes. The in vitro system minimizes an influence of hemodynamic factors that complicate the phenotypes of Cx45 в€’/в€’ mice. Alterations of the electrophysiological properties of the Cx45 в€’/в€’ cardiac myocytes were indicated both by extracellular recording on planar multielectrode array probes and by intracellular Ca 2+ recording of the fluorescent Ca 2+ indicator fura-2. Unlike the coordinated contractions of wild-type cells, differentiated Cx45 в€’/в€’ cardiac myocytes showed high and irregular pulsation rates. In order to determine the specific cardiac muscular function of Cx45, we created Cx45 в€’/в€’ embryonic stem (ES) cells to be differentiated into cardiac muscle in vitro. Cx45-deficient (Cx45 в€’/в€’) mice die of heart failure, concomitantly displaying other complex defects in the cardiovascular system. We hypothesized that the gap junction protein connexin45 (Cx45) regulates early-stage contractions, because it is the only gap junction protein described in early hearts.
