Ageing Theories in Stem Cell

Ageing is the complex process of deterioration of body functions through involvement of body cells and organs. Basically the ageing theory can be divided into two types – hematopoietic stem cell ageing and hair follicle stem cell ageing. Besides these two theories, the other theories of ageing are evolutionary theory, cellular theory, system theory and molecular theory. With ageing the bone marrow cellularity decreases.The foundational microorganism hypothesis of maturing hypothesizes that the maturing procedure is the consequence of the powerlessness of different kinds of immature microorganisms to keep on renewing the tissues of a living being with useful separated cells equipped for keeping up that tissue's unique capacity.
