Summary
Epithelial cells maintain gut barrier function through apical-basal polarity. This review explores novel mechanisms of intestinal epithelial cell polarization in various model organisms.
Area of Science:
- Cell Biology
- Developmental Biology
- Gastroenterology
Background:
- Apical-basal polarity is essential for epithelial cell form and function.
- The gut epithelium forms a critical barrier between the lumen and the body.
- This barrier is vital for tissue homeostasis, pathogen defense, and immune response.
Purpose of the Study:
- To review recent advances in understanding epithelial polarity.
- To focus on novel mechanisms of gut epithelial polarization.
- To highlight research in model organisms like C. elegans, Drosophila, Zebrafish, and Mouse.
Main Methods:
- Literature review of recent scientific publications.
- Focus on studies investigating polarity factors in epithelial cells.
- Comparative analysis across model organisms.
Main Results:
- Conserved polarity factors establish apical-basal polarity in most epithelia.
- Emerging evidence suggests unique polarization mechanisms in the gut epithelium.
- Significant progress in identifying these novel mechanisms across model systems.
Conclusions:
- Understanding gut epithelial polarity is crucial for gastrointestinal health.
- Novel mechanisms of polarization are being uncovered in model organisms.
- Further research in this area promises insights into tissue homeostasis and disease.

01:23Renewal of Intestinal Stem Cells
2.7K
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...

01:21Cell Polarization by Rho Proteins
2.8K
Cell polarity is the asymmetric distribution of cellular and membrane components, making one side of the cell different from the other. This polarity is essential to many processes such as embryogenesis, axon migration, glucose transport across epithelial cells, and directional cell migration. A migrating cell responds to intracellular or extracellular signals via molecular cascades that reorganize the actin cytoskeleton to establish this polarity. In these cells, the Rho family proteins Cdc42,...

01:18Polarity of the Cytoskeleton
19.0K
The intrinsic polarity of cells can be primarily attributed to two factors- i) the asymmetric accumulation of mobile components such are regulatory molecules and subcellular components across the cell and ii) the orientation of polar cytoskeletal filaments that make up the cytoskeletal networks, specifically microfilaments, and microtubules arranged along the axis of polarity. Interactions between the cytoskeletal filaments are crucial for the establishment and maintenance of the polar nature...

01:22Role of Ephrin-Eph Signalling in Intestinal Stem Cell Renewal
2.3K
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.

02:13Determining the Plane of Cell Division
3.4K
Positioning the cell division plane is a critical step during development and cell differentiation, particularly during mitosis when the plane is essential for determining the size of the two daughter cells. The cell division plane is perpendicular to the plane of chromosome segregation, but different types of organisms have different cell division mechanisms to suit their morphology and function.

01:12Role Of Notch Signalling In Intestinal Stem Cell Renewal
2.2K
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...
