Summary
Mitochondrial plasticity is crucial for stem cell function, enabling them to respond to cellular demands and make fate decisions. This review explores how mitochondria regulate stem cell activation and communication.
Area of Science:
- Cell Biology
- Mitochondrial Biology
- Stem Cell Biology
Background:
- Mitochondria are dynamic organelles with significant plasticity.
- Stem cell function relies on plasticity to balance quiescence and activation.
- Mitochondrial plasticity integrates cellular signals to influence stem cell outcomes.
Purpose of the Study:
- To review recent findings on mitochondria's role in stem cell activation and fate decisions.
- To discuss mechanisms of mitochondria-to-nucleus communication in stem cells.
Main Methods:
- Literature review of recent research.
- Analysis of studies on mitochondrial metabolism, dynamics, and signaling in stem cells.
Main Results:
- Mitochondrial plasticity is essential for stem cell fate decisions.
- Tricarboxylic acid (TCA) cycle metabolites link mitochondrial metabolism to epigenetic regulation.
- Mitochondrial dynamics and reactive oxygen species (ROS) influence stem cell transcriptional programs.
Conclusions:
- Mitochondria are key regulators of stem cell activation and fate.
- Mitochondrial plasticity is vital for maintaining stem cell function and tissue homeostasis.
- Further research into mitochondria-nucleus communication pathways is warranted.

9.0K
Among all the organelles in an animal cell, only mitochondria have their own independent genomes. Animal mitochondrial DNA is a double-stranded, closed-circular molecule with around 20,000 base pairs. Mitochondrial DNA is unique in that one of its two strands, the heavy, or H, -strand is guanine rich, whereas the complementary strand is cytosine rich and called the light, or L, -strand. Compared to nuclear DNA, mitochondrial DNA has a very low percentage of non-coding regions and is marked by...

01:20Fates of Pyruvate
10.5K
Pyruvate is the end product of glycolysis, where glucose is oxidized to pyruvate, simultaneously reducing NAD+ to NADH. Two molecules of ATP are also produced by substrate-level phosphorylation.
In aerobic organisms, pyruvate is metabolized via the citric acid cycle to produce reduced coenzymes NADH and FADH2. These coenzymes are then oxidized in the electron transport chain to produce ATP and, in the process, regenerate the NAD+ and FAD. As seen in some cell types and organisms, fermentation...

7.6K
pH plays a critical role in maintaining normal cellular activities. It helps maintain the structure and function of various proteins, dictates the charge on cellular membranes, and is crucial for metabolic reactions inside the cell. Moreover, cells use the energy from the proton motive force to generate ATP.
Cytosolic pH
Under physiological conditions, the cytosolic pH is slightly more acidic than the extracellular pH. However, cells must prevent further acidification of their cytosol to...

01:31Plasticizers
352
Water-reducers, or plasticizers, are chemical admixtures used in concrete to improve strength and workability. These additives reduce the water-cement ratio without compromising workability, lower the cement content while maintaining the same workability, or increase workability to assist concrete placement in inaccessible areas.
Plasticizers function by using surface-active agents to create repulsive electrostatic forces between cement particles. This dispersion enhances the concrete's...

00:58Plasticity
3.0K
Plasticity is the property where an object loses its elasticity and undergoes irreversible deformation, even after the deformation forces are eliminated. If a material deforms irreversibly without increasing stress or load, then this is called ideal plasticity. For example, when a force is applied to an aluminum rod, it changes its shape, but it does not return to its original shape once the force is removed. Plastic deformation or ductility is thus a permanent deformation or change in the...

01:21Plastic Behavior
531
A material's elastic behavior is characterized by the disappearance of stress once the load is removed, allowing the material to return to its original state. However, when stress surpasses the yield point, yielding commences, marking the onset of plastic deformation or permanent set. This change from elastic to plastic behavior is influenced by the peak stress value and the duration before the load is removed. An intriguing observation occurs when a specimen is loaded, unloaded, and...
