objective: the exfoliated human deciduous tooth (shed) contain multipotent stem cells that identified to be a population of highly proliferative and clonogenic .these cells are capable of differentiating into a variety of cell types including neural cells, adipocytes, and odontoblasts. material and methods: normal exfoliated human deciduous incisors collected from six- to nine-years-old childre...

TLX has been shown to play an important role in regulating the self-renewal and proliferation of neural stem cells in adult brains. However, the cellular distribution of endogenous TLX protein in adult brains remains to be elucidated. In this study, we used immunostaining with a TLX-specific antibody to show that TLX is expressed in both neural stem cells and transit-amplifying neural progenito...

Propofol has previously been shown to have detrimental effects on the developing brain. Neural stem cells, identified in the embryonic brain as well as in the adult brain, are multipotent, self-renewing cells, which are capable of differentiating into different phenotypes of the nervous system. The present study was designed to investigate propofol-induced rat embryonic neural stem cell apoptos...

During development, many neural stem cells "age" as they sequentially generate distinct neuronal or glial cell types. In this issue, Maurange et al. (2008) now identify the temporal control factors in Drosophila neural stem cells (neuroblasts) that regulate the fate of stem cell progeny and signal the end of stem cell proliferation.

There is a great potential for the development of new cell replacement strategies based on adult human neural stem-like cells. However, little is known about the hierarchy of cells and the unique molecular properties of stem- and progenitor cells of the nervous system. Stem cells from the adult human brain can be propagated and expanded in vitro as free floating neurospheres that are capable of...

conclusions our data suggest that preconditioning with 5 μm h2o2 + 0.5% fbs and 10 μm h2o2 + 5% fbs improved cell proliferation and viability. however, the mechanisms related to protective properties of preconditioning and using this strategy in stem cell therapy requires more research. background mesenchymal stem cells (mscs) survival decreased following in vivo injection and its application h...

background: due to increasing clinical demand for adipose tissue, a suitable cell for reconstructive adipose tissue constructs is needed. in this study, we investigated the ability of human endometrial-derived stem cells (enscs) as a new source of mesenchymal stem cells to differentiate into adipocytes. enscs are the abundant and easy available source with no immunological response, for cell re...
