Gut and Liver
|July 31, 2024
Summary
The intestine and liver regenerate through cellular plasticity, where differentiated cells regain stem cell properties. This remarkable ability offers potential therapeutic strategies for gut and liver regeneration.
Area of Science:
- Gastroenterology
- Hepatology
- Regenerative Medicine
Background:
- The intestine and liver possess unique regenerative capabilities distinct from other visceral organs.
- Intestinal epithelium undergoes rapid renewal, maintaining homeostasis via intestinal stem cells.
- Hepatic epithelial cells exhibit significant regenerative capacity through proliferation.
Purpose of the Study:
- To review the mechanisms of cellular plasticity in intestinal and liver regeneration.
- To explore the therapeutic potential of harnessing cellular plasticity in the gut and liver.
Main Methods:
- Review of existing literature on intestinal and liver regeneration.
- Analysis of cellular plasticity mechanisms in response to damage and stress.
- Discussion of experimental models demonstrating progenitor cell transitions.
Main Results:
- Differentiated intestinal epithelial cells can regain stem cell properties under stress.
- Hepatocytes and biliary epithelial cells (BECs) can substitute for each other during regeneration.
- Liver progenitor cells can differentiate into hepatocytes/BECs under severe injury conditions.
Conclusions:
- Cellular plasticity is a key mechanism underlying gut and liver regeneration.
- Understanding these mechanisms may lead to novel therapeutic interventions for gastrointestinal and liver diseases.

3.2K
The liver is an important organ in vertebrates that plays an essential role in metabolism. It is also responsible for storing and redistributing nutrients such as carbohydrates, fats, and vitamins in the body. Additionally, the liver releases bile salts which are critical for digesting food and eliminating toxic metabolites from the body.
Cells of Liver
The liver comprises four major types of cells— hepatocytes, stellate, Kupffer, and sinusoidal endothelial cells. The hepatocytes are...

01:23Tissue Renewal without Stem Cells
1.7K
After cellular or tissue damage, the resident stem cells present in the human body can locally repair and regenerate the damaged tissue or organ. However, even though some tissues do not have stem cells, they can repair and regenerate with the help of pre-existing cells. For example, beta cells of the pancreas and hepatocytes of the liver can divide to renew and regenerate the tissue. Here, both cell division and cell death are well regulated by homeostasis.

Regeneration is the process of restoring injured or lost tissues, organs, or body parts. While simpler organisms generally show greater ability to regenerate their whole body, few complex animals show similarly exceptional regeneration. For example, planarian flatworms have a unique regenerative potential making them a popular study organism among biologists to understand the mechanisms of whole body regeneration. Other organisms, such as hydra, also show extreme regeneration potential;...

01:23Renewal of Intestinal Stem Cells
2.5K
The intestinal epithelial lining rapidly renews every 4 to 5 days. The renewal is facilitated by intestinal stem cells (ISCs) located at the base of the crypt– a gland located at the bottom of each villus. ISCs divide asymmetrically to form new stem cells and progenitor daughter cells. The daughter cells are called transit-amplifying (TA) cells which move upwards along the crypt and either differentiate into absorptive cells– the enterocytes or secretory cells– including the...

01:33Adult Stem Cells
28.3K
Stem cells are undifferentiated cells that divide and produce more stem cells or progenitor cells that differentiate into mature, specialized cell types. All the cells in the body are generated from stem cells in the early embryo, but small populations of stem cells are also present in many adult tissues including the bone marrow, brain, skin, and gut. These adult stem cells typically produce the various cell types found in that tissue—to replace cells that are damaged or to continuously...

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.
