Self-renewal is an important character of stem cells. Embryonic stem (ES) cells continue to self-renew in vitro as a pure population, providing a good opportunity to analyze the molecular mechanisms governing self-renewal.
The self-renewing nature of stem cells is a consequence of their ability to proliferate indefinitely while maintaining pluripotency. Mechanisms of pluripotency are well known but mechanisms controlling stem cell proliferation are unknown.
Outlook. These findings challenge the classical view of tissue maintenance by adult tissue-specific stem cells and indicate that stem cell–like self-renewal mechanisms may be activated in mature differentiated cells.
Self-renewal is the process by which stem cells divide to make more stem cells, perpetuating the stem cell pool throughout life. Self-renewal is division with maintenance of the undifferentiated state. This requires cell cycle control and often maintenance of multipotency or pluripotency, depending on the stem cell. Self-renewal programs involve networks that balance proto-oncogenes (promoting

Stem cells self-renew but also give rise to daughter cells that are committed to lineage-specific differentiation. To achieve this remarkable task, they can undergo an intrinsically asymmetric cell division whereby they segregate cell fate determinants into only one of the two daughter cells.
Self-renewal of hESCs is known to be dependent on integrin signaling, whereas self-renewal of mESCs is not . To compare the contribution of two cell adhesion signaling to the self-renewal of the converted hESCs and conventional hESCs, we incubated them in blocking antibodies against E-cadherin and integrin. As predicted, attachment and proliferation of conventional hESCs were strongly affected

Given the central role of this signaling pathway, future studies will need to focus on the downstream mechanisms involved in ES cell self-renewal under such conditions, and ultimately how these findings impact human models of pluripotency.
Symmetric self-renewal generates two stem cells whereas asymmetric self-renewal generates one stem cell and one differentiated progeny cell. At the molecular level, this event can be divided into two mechanisms—preventing differentiation and promoting cell division.

Stem cells from these mice exhibit a diminished capacity for self-renewal and proliferation with age, resulting in increased apoptosis or senescence in the stem cell compartment and depletion of functional stem cells (Ruzankina et al., 2007).
Maintenance of adult tissues depends on sustained activity of resident stem cell populations, but the mechanisms that regulate stem cell self-renewal during homeostasis remain largely unknown.

Sato and co-workers (Sato et al., 2004) recently defined a role for Wnt-dependent signaling in self-renewal of human and murine ES cells that functions independently of LIF and STAT3. Moreover, suppression of GSK3β, an antagonist of Wnt signaling, is sufficient to maintain self-renewal and pluripotency of human and murine ES cells in the
