Umbilical cord mesenchymal stem cells (UCMSCs) retain their intrinsic stem cell potential while at the same time displaying high proliferation rates, powerful differentiation capacity, and low immunogenicity.
The unique properties of nanomaterials and nanostructures could be particularly useful in controlling intrinsic stem cell signals and in dissecting the mechanisms underlying embryonic and adult stem cell behavior.
These reports have led millions of people worldwide to hope that regenerative medicine is about to revolutionise biomedicine: either through transplantation of cells grown in the laboratory, or by finding ways to stimulate a patient's intrinsic stem cells to repair diseased and damaged organs.
The pCSCs are much more potent in tumor vasculogenesis than the differentiated tumor monocytic cells (TMCs) from the same tumor, which had comparable or even higher capacity to produce some vascular growth factors, suggesting that the potent tumor vasculogenesis of pCSCs is associated with their intrinsic stem-like property.
Target mRNAs were designed to be cis-repressed RNA (crRNA) by the inclusion of a 5′ intrinsic stem-loop structure that encompassed the RBS.
Hence the 3'UTR and coding regions of upstream transcribed ORFs of transcribed pseudogenes were analyzed for intrinsic stem loop terminator structures.
In sum, the Drosophila midgut provides an outstanding tissue in which to explore and understand the significance of intrinsic stem cell differences.
These findings suggest that local dermal or systemic environmental, rather than intrinsic stem cell alterations, may be the dominant factors that regulate normal skin aging.
However, whether anaerobic metabolism is an adaptation to low oxygen levels in the specific niches in vivo or is an intrinsic stem cell property is still unclear.
Photo-aging models have demonstrated that both epidermal stem cells and their progeny can accumulate DNA damage upon UV irradiation, although no studies have addressed whether this damage alters intrinsic stem cell functionality (Nijhof et al., 2007).
