Reconstituting 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 کاملGene expression profile of murine long-term reconstituting vs. short-term reconstituting hematopoietic stem cells.
The hematopoietic stem cell (HSC) compartment is composed of long-term reconstituting (LTR) and short-term reconstituting (STR) stem cells. LTR HSC can reconstitute the hematopoietic system for life, whereas STR HSC can sustain hematopoiesis for only a few weeks in the mouse. Several excellent gene expression profiles have been obtained of the total hematopoietic stem cell population. We have u...
متن کاملMammalian Spermatogenesis
The formation of mature spermatozoa is one of the most essential functions in life. A concerted sequence of events is needed to proliferate, maintain and mature germ cells starting with spermatogonial stem cells and culminating in mature gametes. Apart from the genetic background, this process requires highly organized tissue in which the complex process of spermatogenesis is strongly regulated...
متن کاملMammalian 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 کاملSpermatogenesis after transplantation of adipose tissue-derived mesenchymal stem cells in busulfan-induced azoospermic hamster
Objective(s): Adipose tissue-derived mesenchymal stem cells (AT-MSCs) with more potent immunomodulatory effects, greater proliferative potential and secretion of growth factors and cytokines in comparison with bone marrow derived MSCs are more appropriate for cell therapy. The aims of the present study were to evaluate the histomorphometric effect of AT-MSCs allotransplantation on regeneration ...
