Summary
Stem cells can replace themselves through dedifferentiation, a process with common features across species. This review explores the hallmarks of stem cell dedifferentiation and its role in tissue repair.
Area of Science:
- * Stem cell biology
- * Developmental biology
- * Regenerative medicine
Background:
- * Adult stem cells are crucial for tissue homeostasis, generating new cells.
- * Recent research highlights stem cell dedifferentiation as a replacement mechanism.
- * Dedifferentiation capacity and mechanisms differ across species and organs.
Purpose of the Study:
- * To summarize the key characteristics ('hallmarks') of stem cell dedifferentiation.
- * To review the mechanisms underlying stem cell potency maintenance, loss sensation, and migration during dedifferentiation.
- * To discuss the current understanding of dedifferentiation as a genuine stem cell replacement strategy.
Main Methods:
- * Comprehensive literature review of studies on stem cell dedifferentiation.
- * Synthesis of findings on common features and mechanisms of dedifferentiation.
- * Analysis of the role of dedifferentiation in tissue homeostasis and regeneration.
Main Results:
- * Identified common hallmarks of dedifferentiation, including potency maintenance and migration.
- * Highlighted the variability in dedifferentiation capacity across different biological contexts.
- * Presented dedifferentiation as a significant mechanism for stem cell replacement.
Conclusions:
- * Dedifferentiation is a fundamental process enabling stem cells to replace themselves.
- * Understanding dedifferentiation mechanisms offers insights into regenerative potential.
- * Further research is needed to fully elucidate the complexities of dedifferentiation in vivo.

2.5K
How does a complex organism such as a human develop from a single cell? It all starts from a single fertilized egg which gives rise to a vast array of cell types, such as nerve cells, muscle cells, and epithelial cells that characterize the adult? Throughout development and adulthood, cellular differentiation leads cells to assume their final morphology and physiology. Differentiation is the process by which unspecialized cells become specialized to carry out distinct functions.

01:28Forced Transdifferentiation
1.8K
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.

During embryogenesis, cells become progressively committed to different fates through a two-step process: specification followed by determination. Specification is demonstrated by removing a segment of an early embryo, “neutrally” culturing the tissue in vitro—for example, in a petri dish with simple medium—and then observing the derivatives. If the cultured region gives rise to cell types that it would normally generate in the embryo, this means that it is specified. In...

01:22Diversity in Cell Signaling Responses
6.3K
The physiological function of a cell and cellular communication are outcomes of a range of extrinsic signals, intracellular signaling pathways, and cellular responses. No two cell types express the same repertoire of signaling components. Receptors are highly selective for their cognate ligands, but once activated, they can alter multiple cellular processes such as DNA transcription, protein synthesis, and metabolic activity.

01:30Overview of Cell Death
5.5K
Cell death is an essential process where the body gets rid of old or damaged cells. Cell proliferation and death need to be balanced, as an imbalance between the two may lead to cancer or autoimmune diseases.
Cell death was observed in the early 19th century, but there was no experimental evidence to prove it. In 1842, Carl Vogt first discovered cell death in a metamorphic toad; however, it was not termed ‘cell death.’ Scientists discovered different cell death pathways only in the...

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.
