Summary
Stem cell metabolism is key for self-renewal and differentiation. Nutrient metabolites link metabolism, signaling, and epigenetics to control cell fate and tissue regeneration.
Area of Science:
- Stem cell biology
- Metabolic regulation
- Epigenetics
Background:
- Stem cells possess metabolic plasticity enabling self-renewal and lineage specification.
- Metabolites influence stem cell function beyond energy provision.
- Stem cell metabolism is crucial for tissue homeostasis and regeneration.
Purpose of the Study:
- To review recent advances in understanding the link between stem cell metabolism and cell fate control.
- To highlight the role of nutrient-responsive metabolites in stem cell signaling and epigenetic regulation.
- To discuss the potential of targeting stem cell metabolism for therapeutic applications in aging and disease.
Main Methods:
- Literature review of recent research on stem cell metabolism and cell fate.
- Synthesis of findings on the interplay between metabolic flux, signaling pathways, and epigenetic modifications.
- Discussion of emerging concepts and future directions in the field.
Main Results:
- Metabolic plasticity is essential for stem cell function.
- Nutrient-derived metabolites act as signaling molecules influencing cell fate.
- Metabolic pathways are intertwined with epigenetic mechanisms that regulate gene expression.
- Targeting stem cell metabolism shows promise for regenerative medicine.
Conclusions:
- Stem cell metabolism is a critical determinant of cell fate.
- Metabolites play a central role in mediating crosstalk between metabolism, signaling, and epigenetics.
- Modulating stem cell metabolism offers a promising strategy for enhancing tissue repair and combating age-related decline.

01:14Maintenance of the ES Cell State
The cells of the blastocyst inner cell mass only remain pluripotent for a short time. This state of pluripotency and self-renewal can be maintained in embryonic stem (ES) cell culture by adding specific chemicals or growth factors to ensure the cells can continue dividing and later differentiate into different cell types. In some cases, the cells are grown on a feeder layer of differentiated cells, which provides the growth factors and extracellular matrix components necessary for stem cell...
01:17Stem Cell Culture
Stem cell research aims to find ways to use stem cells to regenerate and repair cellular damage. Over time, most adult cells undergo the wear and tear of aging and lose their ability to divide and repair themselves. Stem cells do not display a particular morphology or function. Adult stem cells, which exist as a small subset of cells in most tissues, keep dividing and can differentiate into a number of specialized cells generally formed by that tissue. These cells enable the body to renew and...
01:28Forced Transdifferentiation
Transdifferentiation, also known as lineage reprogramming, was first discovered by Selman and Kafatos in 1974 in silkmoths. They observed that the moths’ cuticle-producing cells transformed into salt-producing cells. Many such cases of natural transdifferentiation occur in organisms. In humans, pancreatic alpha cells can become beta cells. In newts, the loss of the eye’s lens causes the pigmented epithelial cells to transdifferentiate into the lens cells.

01:26Stem Cell Niche
The stem cell niche is the dynamic microenvironment where stem cells reside. Inside these niches, the cells may remain undifferentiated, undergo high self-renewal, or become lineage-specific progenitors. Stem cells coexist with other niche cells, such as stromal cells. They also interact closely with the ECM. Cell-cell and cell-matrix communication occur via adhesion molecules or soluble factors that signal the stem cells and determine their fate. Stromal cells also provide survival signals to...
01:29Somatic to iPS Cell Reprogramming
Reprogramming alters the gene expression in somatic cells, transforming them into induced pluripotent stem (iPS) cells over several generations. Scientists can reprogram cells by introducing genes for four transcription factors—Oct4, Sox2, Klf4, and c-Myc (OSKM) by viral or non-viral methods. These factors are also known as Yamanaka factors after Shinya Yamanaka, who first generated iPS cells using mouse skin cells. Yamanaka was awarded the Nobel Prize in Physiology or Medicine in 2012 for this...
01:22iPS Cell Differentiation
The ability of induced pluripotent stem cells or iPSCs to differentiate into most body cell types has stimulated repair and regenerative medicine research over the past few decades. iPSC-derived blood cells, hepatocytes, beta islet cells, cardiomyocytes, neurons, and other cell types can repair injuries or regenerate damaged tissue in diseases such as diabetes and neurodegenerative disorders.
