摘要: One of the most fascinating challenges in developmental biology is to elucidate mechanisms that control organization body plan during embryonic development. In this regard intercellular transduction signals particular importance for a coordinated pattern cell differentiation. Because their ability allow exchange ions and small molecules up molecular weight about 1200 D (Simpson et al., 1977), gap junctions have been proposed as putative pathway transfer developmentally important (Furshpan Potter, 1968). embryos so far studied appear early stages development, when decisions take place (see Caveney, 1985; Guthrie, 1987 reviews). More striking results shown differences junctional communication may be found between tissues with different programmes. The changes functional cells divergent fates suggest an involvement junctional-mediated signal specialization domains embryo (Van den Biggelaar, 1988).
