Answer #1

Cells move calcium to neighbouring cells or to the next cellular compartmnets through gap junctions. Other molecules are also transported through this gap junctions.These junctions consist of connexin proteins which form pores between the cells allowing exchange of the various substances to pass through them. In the case of endothelial cells. Gap junctions directly link the cytoplasms of cells and allow exchange of ions and secondary messengers, including calcium and IP3. Furthermore, many cell types are known to communicate by releasing diffusible factors into the microenvironment. Once calcium release in a cell has been stimulated, the signal are transferred to neighboring cells via gap junction intercellular communication (GJIC). The transfer of the calcium signal results in a spatiotemporal propagation of intercellular calcium wave communicating a signal between neighboring cells.

    Drosopholia eye development is an example of cell differentiation directed by signal binding to a receptor tyrosine kinase (RTK). In this pathway, R7 photoreceptor development requires a receptor (SEV, sevenless), which is activated by binding to a plasma membrane bound signal (BOSS, bride-of-sevenless) displayed on the adjacent R8 cell Receptor activation leads to activation of RAS via two proteins, Drk (down- stream of receptor kinases) and Sos (son-of-sevenless). Activated RAS leads to activation of a phosphorylation cascade that activates the...
