Self-renewal and differentiation
The adult human heart has limited regenerative capacity and, theref fore, functional restoration of the damaged heart presents a great challenge. Despite the progress achieved in the pharmacological and surgical treatment of degenerative myocardial diseases, they are still considered a major cause of morbidity and mortality in the western world. Repopulation of the damaged heart with cardiomyof...
متن کاملSelf-Renewal of Stem Cells
Asymmetric division is one of the most fundamental characteristics of adult stem cells , which ensures one daughter cell maintains stem cell status and the other daughter cell becomes committed to differentiation. New data emerged recently that allow us to conclude that asymmetric division has another important aspect: it enables self-maintenance of stem cells.
متن کاملMuscle satellite cell heterogeneity and self-renewal
Adult skeletal muscle possesses extraordinary regeneration capacities. After muscle injury or exercise, large numbers of newly formed muscle fibers are generated within a week as a result of expansion and differentiation of a self-renewing pool of muscle stem cells termed muscle satellite cells. Normally, satellite cells are mitotically quiescent and reside beneath the basal lamina of muscle fi...
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 کاملCancer stem cells and self-renewal.
The cancer stem cell (CSC) or cancer-initiating cancer (C-IC) model has garnered considerable attention over the past several years since Dick and colleagues published a seminal report showing that a hierarchy exists among leukemic cells. In more recent years, a similar hierarchical organization, at the apex of which exists the CSC, has been identified in a variety of solid tumors. Human CSCs a...
