Stem cells in the arrangement of bone marrow repopulation and regenerative medicine

Hematopoiesis is a permanent and complex event in which a spectrum of different mature blood cells from a small population of toti/pluri/multipotent stem cells (SCs) are produced through a variety of proliferative and differentiative processes. Hematopoietic SCs are defined as the cells with extensive self–renewal and proliferative potential, together with their ability to differentiate into all blood–cell lineages. Many studies have demonstrated that a multifactorious network of interactive cytokines and other blood–derived mediators regulate the survival, maturation, and proliferation of SCs .
