Summary
Paneth cells in the gut support the energy needs of intestinal stem cells (ISCs). This interaction is crucial for maintaining ISC function and self-renewal in organoid cultures.
Area of Science:
- Gastroenterology
- Stem Cell Biology
- Cellular Metabolism
Background:
- Single Lgr5 intestinal stem cells (ISCs) can be cultured in vitro to form self-organizing epithelial organoids.
- These organoids mimic intestinal differentiation and require signals from the stem cell niche.
- Paneth cells are key components of the ISC niche, secreting essential growth factors.
Purpose of the Study:
- To investigate the role of Paneth cells in supporting the metabolic state of intestinal stem cells.
- To understand the contribution of Paneth cells to ISC function in organoid models.
Main Methods:
- Utilized in vitro organoid culture systems derived from single Lgr5+ ISCs.
- Analyzed the metabolic interactions between Paneth cells and ISCs within these organoids.
Main Results:
- Demonstrated that Paneth cells actively support the metabolic state of ISCs.
- Highlighted the critical role of Paneth cells in providing essential metabolic signals for ISC maintenance and function.
Conclusions:
- Paneth cells are essential for sustaining the metabolic requirements of intestinal stem cells.
- This metabolic support is vital for the self-renewal and differentiation capacity of ISCs in organoid models.

01:23Renewal of Intestinal Stem Cells
3.4K
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...

01:12Role Of Notch Signalling In Intestinal Stem Cell Renewal
2.5K
Notch signaling was first discovered in Drosophila melanogaster, where it is involved in cell lineage differentiation. Notch signaling regulates the maintenance and differentiation of intestinal stem cells or ISCs by controlling the expression of atonal homolog 1 or Atoh1. Atoh1 directs cells to differentiate into secretory cells.
Direct cell-to-cell contact is needed for the activation of Notch signaling. The signal is initiated when a notch ligand binds to a receptor on an adjacent cell, also...

2.7K
Erythropoietin-producing hepatocellular carcinoma receptor (Eph) and its ligand, Eph receptor-interacting protein (Ephrin) were first discovered in the human carcinoma cell line, hence the name. Ephrin-Eph interaction guides cells to reach their appropriate location in adult tissues. They also play an essential role in the immune system by helping in immune cell migration, adhesion, and activation. Based on their structure and function, Eph is divided into two classes — EphA and EphB.

01:33Adult Stem Cells
34.0K
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...

01:26Stem Cell Niche
6.5K
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...

01:23Tissue Renewal without Stem Cells
2.2K
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.
