Mammalian neural stem cells.
Neural stem cells exist not only in the developing mammalian nervous system but also in the adult nervous system of all mammalian organisms, including humans. Neural stem cells can also be derived from more primitive embryonic stem cells. The location of the adult stem cells and the brain regions to which their progeny migrate in order to differentiate remain unresolved, although the number of ...
متن کاملReconstituting mammalian spermatogenesis using stem cells.
W hile stock markets and economies are smoldering all over the world, stem cell science is on fire. The promise of curing many untreatable forms of human male infertility is now one small step closer based on a recent paper in Cell. In this work, scientists from Kyoto University in Japan created mature, fertile sperm from embryonic and induced pluripotent stem cells by grabbing the primitive ge...
متن کاملStem cells in aged mammalian ovaries
ovary undergoes several changes after the menopause. The main characteristics of the post-menopausal ovary are a loss of follicles and several changes as a consequence of apoptotic processes. Signs of atrophy and fibrosis are evident. Primordial follicles are usually absent in postmenopause, whereas corpora atretica, hemorrhagica and albicantia, scar tissue, and simple follicular cysts are comm...
متن کاملNeural stem cells in mammalian development.
Neural stem cells (NSCs) are primary progenitors that give rise to neurons and glia in the embryonic, neonatal and adult brain. In recent years, we have learned three important things about these cells. First, NSCs correspond to cells previously thought to be committed glial cells. Second, embryonic and adult NSCs are lineally related: they transform from neuroepithelial cells into radial glia,...
متن کاملEpigenetic regulation of mammalian stem cells.
Two critical properties of stem cells are self-renewal and multipotency. The maintenance of their "stemness" state and commitment to differentiation are therefore tightly controlled by intricate molecular networks. Epigenetic mechanisms, including DNA methylation, chromatin remodeling and the noncoding RNA-mediated process, have profound regulatory roles in mammalian gene expression. Recent stu...
