E-Cadherin regulates neural stem cell self-renewal.
E-Cadherin, a cell adhesion protein, has been shown to take part in the compartmentalization, proliferation, survival, and differentiation of cells. E-Cadherin is expressed in the adult and embryonic forebrain germinal zones in vivo, and in clonal colonies of cells derived from these regions and grown in vitro. Mice carrying E-Cadherin floxed genes crossed to mice expressing Cre under the Nesti...
متن کاملMechanisms of stem cell self-renewal.
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 ...
متن کاملEmbryonic Stem Cell Self-Renewal, Analyzed
Maintaining the pluripotency of mouse ES cells requires both LIF (leukemia inhibitory factor) and unknown factors in serum. The paper from Ying et al. in this issue of Cell shows that BMP (bone morphogenetic protein) can replace serum in this capacity, defining molecular requirements for ES cell self-renewal.
متن کاملPten, Tumorigenesis, and Stem Cell Self-Renewal
Self-renewal pathways crucial for maintaining stem cells are deregulated in cancer, raising the spectre that cancer therapies targeting such pathways might also ablate normal stem cells. As Yilmaz et al. (2006) report in a recent Nature paper, this may not be the case for the tumor suppressor protein Pten, which drives the self-renewal of normal hematopoietic stem cells and the formation of leu...
متن کاملRegulation of hematopoietic stem cell self-renewal.
Every day, billions of new blood cells are produced in the body, each one derived from a hematopoietic stem cell (HSC). Because most mature blood stem cells have a limited life span, the ability of HSCs to perpetuate themselves through self-renewal and generate new blood cells for the lifetime of an organism is critical to sustaining life. A key problem in hematopoietic stem cell biology is how...
