... into pluripotent stem cells, which have the ability to generate all other types of cells and tissues of a given organism. Cellular reprogramming is thus a complex process that requires extensive modification at the epigenetic and transcriptional level, unlocking cellular programs that allow cells to acquire...

..., including spores, oocytes and adult stem cells. We begin by defining quiescent cells and discussing their roles in key biological processes. We then examine metabolic factors that influence cellular quiescence in both healthy and disease contexts, and how these could be leveraged in the treatment of cancer...

... in specific cells ( Visvader, 2011 ; Gilbertson, 2011 ; Skibinski and Kuperwasser, 2015 ). A hierarchy exists in the mammary epithelium where embryonic bipotent mammary epithelial stem cells (MaSCs) generate unipotent luminal and basal progenitors that are responsible for the generation and maintenance...

... application of electric stimulation enables cellular plasticity and the re-establishment of stem cell activity in tissues damaged by ionizing radiation. We show that subthreshold direct current stimulation (DCS) rapidly restores pluripotent stem cell populations previously eliminated by lethally γ-irradiated...

...-derived apolipoprotein A1 (APOA1) was associated with an increase in the Lin − Sca-1 + Kit + (LSK) bone marrow stem cell population and lymphoid-primed multipotent progenitor numbers, which translated into a higher production and systemic flux of T cell subsets. In accordance with APOA1 deficiency...

Furthermore, Smed-Sirt-1(RNAi) animals displayed reduced cell death and increased stem cell proliferation accompanied by impaired expression of intestinal lineage progenitors and reduced branching of the gut. Taken together, our findings indicate that Sirtuin-1 is a crucial metabolic hub capable...

An alternative hypothesis suggests that certain cells segregate sister chromatids non...
