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

Stem Cell Cytokines: Current Roles, Regulation, and Impact Biology Diagrams

Stem cells persist throughout the lifespan to repair and regenerate tissues due to their unique ability to self-renew and differentiate. Here we reflect on the recent discoveries in stem cells that highlight a mitochondrial metabolic checkpoint at the restriction point of the stem cell cycle. Mitochondrial activation supports stem cell proliferation and differentiation by providing energy 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 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

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. 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 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

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
