Stem Cell Apoptosis and Signal Transduction

By induction of apoptosis, self-renewal and proliferation of stem cell population is controlled. Apoptosis of stem cells is a dynamic process which changes accordingly to the response to environmental conditions. The number of stem cells are always balanced between the lost through differentiation and to the gained through proliferation. Self-renewal and multiplication is controlled to some degree by the affectation of apoptosis. Because of natural conditions apoptosis of immature microorganisms is accepted to be dynamic.
