Stem Cells Divide and New Keratinocytes Are Produced
Repair of critically short or uncapped telomeres by. However the most utilized keratinocytes in primary cell culture are normal human epidermal keratinocytes NHEK cells isolated from neonatal or adult skin the latter of which is significant for the study of adult diseases such as psoriasis. Are There Cancer Stem Cells Fastbase Epithelial Stem Cells and Their Lineages. . Stem cells are undifferentiated cells that have the capacity to proliferate in undifferentiated cells both in vitro and in vivo self-renewal and to differentiate into mature specialized cells. Epidermal thickenings called Rete ridges or rete pegs extend downward between dermal papillae. At least a few hundred nucleotides of telomere repeats must cap each chromosome end to avoid activation of DNA repair pathways. Keratinocytes can be isolated from different locations of the body such as the lining of the oral cavity human oral keratinocytes. They replace old...
