Mitophagy-driven mitochondrial rejuvenation regulates stem cell fate
Our understanding on how selective mitochondrial autophagy, or mitophagy, can sustain the archetypal properties of stem cells is incomplete. PTEN-induced putative kinase 1 (PINK1) plays a key role in the maintenance of mitochondrial morphology and function and in the selective degradation of damaged mitochondria by mitophagy. Here, using embryonic fibroblasts fromPINK1 gene-knockout (KO) mice, ...
متن کاملConnecting Mitochondria, Metabolism, and Stem Cell Fate
As sites of cellular respiration and energy production, mitochondria play a central role in cell metabolism. Cell differentiation is associated with an increase in mitochondrial content and activity and with a metabolic shift toward increased oxidative phosphorylation activity. The opposite occurs during reprogramming of somatic cells into induced pluripotent stem cells. Studies have provided e...
متن کاملEnergy metabolism in adult neural stem cell fate.
The adult mammalian brain contains a population of neural stem cells that can give rise to neurons, astrocytes, and oligodendrocytes and are thought to be involved in certain forms of memory, behavior, and brain injury repair. Neural stem cell properties, such as self-renewal and multipotency, are modulated by both cell-intrinsic and cell-extrinsic factors. Emerging evidence suggests that energ...
متن کاملIRF4 Couples Anabolic Metabolism to Th1 Cell Fate Determination
Anabolic metabolism in lymphocytes promotes plasmablast and cytotoxic T cell differentiation at the expense of self-renewal. Heightened expression and function of the transcription factor IFN regulatory factor 4 (IRF4) accompany enhanced anabolic induction and full commitment to functional differentiation in B cells and CD8+ T cells. In this study, we used a genetic approach to determine whethe...
متن کاملStochasticity and cell fate.
Fundamental to living cells is the capacity to differentiate into subtypes with specialized attributes. Understanding the way cells acquire their fates is a major challenge in developmental biology. How cells adopt a particular fate is usually thought of as being deterministic, and in the large majority of cases it is. That is, cells acquire their fate by virtue of their lineage or their proxim...
