WebThe cells of animal tissues such as the intestinal epithelium are linked together at their apical ends in order to prevent substances from passing between them. The type of cell junction linking these cells in this way is called a (n) _______. Tight Junction WebCell signaling allows cells to communicate with each other through signal transduction pathways. When a paper cut damages skin cells in a finger, the cells near the cut must begin producing new cells to replace the cells that were lost. Growth factor signal molecules are released into the extracellular spaces near the cut. heimulinWebAt gap junctions, membrane proteins called connexins form tiny fluid-filled tunnels called connexons that connect neighboring cells (Figure 4-1e). The plasma membranes of gap junctions are not fused together as in tight junctions but are separated by a very narrow intercellular gap (space). heimuli
