Gap junctions in development.
Almost since their discovery gap junctions have attracted attention as possible means by which cell growth and cell development could be controlled since they provide for direct cell-cell communication (Potter et al, 1966; Loewenstein, 1968; Sheridan, 1968; Crick, 1970; Bennett, 1973). A corollary, of course, is that gap junctions play an important role in embryogenesis. This idea is made espec...
متن کاملGap Junctions
Gap junctions are sites of intercellular communication where cells are interconnected by small aqueous channels (Figure 1b). The term is morphological, for in transmission electron micrographs of thin sections, the unit membranes of the joined cells are seen to remain separated by a gap of about 2 nm (Figure 1a, inset). The gap of gap junctions distinguishes them from tight junctions, or zonula...
متن کاملGap junctions
In vertebrates and invertebrates, signaling among neurons is most commonly mediated by chemical synapses. At these synapses neurotransmitter released by presynaptic neurons is detected by receptors on the postsynaptic neurons, leading to an influx of ions through the receptors themselves or through channels activated by intracellular signaling downstream of the receptors. But neurons can commun...
متن کاملIntercellular communication in preimplantation development: the role of gap junctions.
Gap junctions are sites where intercellular membrane channels are clustered that allow neighboring cells to pass small molecules directly between them. Gap junctional intercellular communication has been implicated in a variety of human diseases. Gap junction channels are assembled from a large family of proteins called connexins with each type of channel having some unique properties. Preimpla...
متن کاملThe role of gap junctions in amphibian development.
The possibility that communication through gap junctions may be important during embryonic development has often been raised since gap junctions were first described between early embryonic cells. It is now known that this direct cell-to-cell communication pathway disappears between groups of embryonic cells with different developmental fates as the embryo progresses through development, sugges...
