Summary
Neonatal intestinal stem cells (ISCs) development is regulated by niche signaling pathways. Understanding these pathways is crucial for intestinal regeneration and treating necrotizing enterocolitis (NEC).
Area of Science:
- Gastroenterology
- Developmental Biology
- Stem Cell Biology
Background:
- Intestinal epithelial cells are rapidly replaced by intestinal stem cells (ISCs).
- ISC self-renewal and differentiation are regulated by niche signaling pathways.
- Mechanisms governing neonatal ISC niche development are less understood than in adults.
Purpose of the Study:
- To review morphogenetic and immune pathways regulating neonatal intestinal stem cells.
- To highlight the role of pathway crosstalk in intestinal tissue regeneration.
- To discuss pathway perturbations in necrotizing enterocolitis (NEC) and potential stem cell therapies.
Main Methods:
- Literature review of morphogenetic and immune signaling pathways.
- Analysis of cross-talk among pathways in neonatal intestinal development and regeneration.
- Review of pre-clinical models of NEC and stem cell therapy options.
Main Results:
- Key signaling pathways critical for neonatal ISC niche development and maintenance were identified.
- The interplay between morphogenetic and immune pathways significantly impacts intestinal regeneration.
- Perturbations in these pathways are implicated in NEC pathogenesis.
Conclusions:
- Understanding neonatal ISC niche regulation is vital for addressing NEC.
- Targeting specific signaling pathways may offer therapeutic strategies for intestinal regeneration in NEC.
- Further research into stem cell therapy for NEC is warranted based on pre-clinical findings.

01:23Renewal of Intestinal Stem Cells
2.9K
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
2.3K
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...

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...

01:22Role of Ephrin-Eph Signalling in Intestinal Stem Cell Renewal
2.4K
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.

01:26Stem Cell Niche
5.7K
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...
