Mitogens are important in cancer research due to their effects on the cell cycle. Cancer is in part defined by a lack of, or failure of, control in the cell cycle. This is usually a combination of two abnormalities: first, cancer cells lose their dependence on mitogens. Second, cancer cells are resistant to anti-mitogens. Rather than requiring endogenous or external mitogens to continue the cell cycle, cancer cells ar…
SpletThis cycle consists of three phases: G1, S, G2 The first phase represents cell growth while the last two phases represent cell division.
