Summary
Intestinal stem cells (ISCs) maintain gut health. Nutrients like lipids, carbs, and vitamin D significantly impact ISC proliferation and differentiation, influencing disease risk.
Area of Science:
- Gastroenterology
- Cell Biology
- Metabolism
Background:
- Intestinal stem cells (ISCs) possess high proliferative capacity, crucial for gut epithelium renewal.
- Dysregulated ISC homeostasis is linked to diseases, including cancer.
- Nutrients and metabolic pathways are increasingly recognized as key regulators of ISC fate.
Purpose of the Study:
- To review recent findings on how nutrients influence intestinal stem cell (ISC) proliferation and differentiation.
- To highlight the role of lipids, carbohydrates, and vitamin D in maintaining ISC homeostasis.
Main Methods:
- Literature review of recent research.
- Analysis of studies investigating nutrient-metabolic pathways and ISC fate.
Main Results:
- Nutrients extensively modulate ISC proliferation and differentiation.
- Specific nutrients like lipids, carbohydrates, and vitamin D play critical roles in ISC balance.
- Metabolic pathways are central to nutrient-mediated control of ISC fate.
Conclusions:
- Precise control of ISC homeostasis is vital for intestinal integrity.
- Dietary factors and metabolic state significantly impact ISC behavior.
- Understanding these interactions is key for preventing and treating gut-related diseases.

01:12Role Of Notch Signalling In Intestinal Stem Cell Renewal
2.1K
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...

01:23Renewal of Intestinal Stem Cells
2.6K
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
29.0K
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
5.1K
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...

01:22Role of Ephrin-Eph Signalling in Intestinal Stem Cell Renewal
2.2K
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.

01:19Multipotency of Hematopoietic Stem Cells
3.1K
The hematopoietic stem cells or HSCs are multipotent, meaning they can differentiate and give rise to all blood and immune cells. HSCs are maintained in the quiescent stage until an external stimulus initiates their differentiation. The multipotent HSCs exist as two heterogeneous populations, long-term repopulating cells (LTRC) and short-term repopulating cells (STRC). The two HSC populations have different surface markers or receptors and are classified based on quiescence and long-term...
