This review will hereby focus on the role of essential fatty acids and their metabolites in the regulation of stem cell proliferation and differentiation. Essential Fatty Acid Metabolism and Cell Proliferation and Differentiation. Lipids have long been considered to be the building blocks of cellular membranes and adipose tissues as well as Transcription is known to tightly regulate gene expression profiles in stem and differentiating cells, but less is known about the role of translational control. This study identifies that signals from the stem cell niche induce changes in translational rates, regulated through eIF3d1 phosphorylation, to control stem cell fate in a Drosophila testis model.
Translational control of stem cell function Biology Diagrams
Stem cells are well known to be controlled transcriptionally, but recent studies indicate that pluripotency, cell fate and differentiation depend on the regulation of translation and ribosome
Understanding their function, regulation, and interactions with other cells is crucial for harnessing their therapeutic potential. Growth factors coordinate stem cell proliferation, differentiation, and survival. Epidermal growth factor (EGF) promotes neural stem cell expansion and neurogenesis. Platelet-derived growth factor (PDGF) aids In this review, we discuss our current knowledge of how cell cycle proteins mechanistically link cell proliferation, pluripotency and cell fate specification. We focus on embryonic stem cells, induced pluripotent stem cells, and embryonic neural stem/progenitor cells. Cheung TH & Rando TA Molecular regulation of stem cell quiescence. Nat
Stem Cell Cytokines: Current Roles, Regulation, and Impact Biology Diagrams
Growing evidence indicates that this machinery operates in a distinct fashion in some mammalian stem cell types, such as pluripotent embryonic stem cells. The cell cycle in stem cell proliferation, pluripotency and differentiation Nat Cell Biol. 2019 Sep;21(9):1060-1067. doi: 10.1038/s41556-019-0384-4. Summary. Human embryonic stem (hES) cells show an atypical cell cycle regulation characterized by a high proliferation rate and a short G1-phase [1, 2].In fact, a shortened G1-phase might protect ES cells from external signals inducing differentiation, as shown for certain stem cells [].It has been suggested that self-renewal and pluripotency are intimately linked to cell cycle regulation in The mitochondrial pyruvate carrier MPC1 is dynamically regulated in neural stem cells (NSCs), and in vitro and in vivo genetic ablation of MPC1 leads to NSC activation. 55 Similarly, deletion of MPC1 in intestinal stem cells (ISCs) leads to increased stem cell proliferation in vivo and in vitro organoid formation. 56 In hair follicle stem cells
