The cell cycle is controlled by many cell cycle control factors, namely cyclins, cyclin-dependent kinases (Cdks) and cyclin-dependent kinase inhibitors (CKIs). What are internal and external factors regulators and how are they related to cellular division? WebThe cells of a multicellular organism are members of a highly organized community. The number of cells in this community is tightly regulated—not simply by controlling the rate of cell division, but also by controlling the …

For the most part, each group contains both … Mitogens can be either endogenous or exogenous factors. Endogenous mitogens function to control cell division is a normal and necessary part of the life cycle of multicellular organisms. For example, in zebrafish, an endogenous mitogen Nrg1 is produced in response to indications of heart damage. When it is expressed, it causes the outer layers of the heart to respond by increasing division rates and producing new layers of heart muscle cells to replace the damage…
