Summary
Epithelial cell migration in the adult intestine is poorly understood. This review explores the structure of the intestinal epithelium and wound healing studies to shed light on cell movement mechanisms.
Area of Science:
- Cell Biology
- Gastroenterology
- Tissue Engineering
Background:
- In vitro studies have advanced understanding of cytoskeleton and matrix receptors in cell locomotion.
- The mechanism of epithelial cell migration in the adult intestine remains unclear.
- The epithelial cell cytoskeleton primarily maintains the apical region, brush border, and adhesion complexes.
Purpose of the Study:
- To review current knowledge on epithelial migration in the context of intestinal epithelial structure.
- To explore insights from wound healing studies relevant to epithelial migration.
- To identify future research directions for understanding intestinal epithelial cell movement.
Main Methods:
- Review of existing literature on epithelial structure and cell migration.
- Analysis of findings from in vitro and in vivo studies.
- Synthesis of information from wound healing research.
Main Results:
- The apical cytoskeleton is crucial for brush border and barrier function.
- The basal cytoskeleton's role in migration is less understood.
- Wound healing models offer insights into epithelial sheet movement.
Conclusions:
- Further research is needed to elucidate the mechanisms of basal epithelial cell migration.
- Integrating knowledge of epithelial structure and wound healing is key.
- Future studies should focus on the basal cytoskeleton's role in intestinal cell movement.

01:09Cell Migration
Cell migration, the process by which cells move from one location to another, is essential for the proper development and viability of organisms throughout their life. When cells are not able to migrate properly to their ordained locations, various disorders may occur. For example, disruption in cell migration causes chronic inflammatory diseases such as arthritis.
01:19Cell Migration
Cell migration is a process by which the cells move from one location to another, playing an essential role in embryological development, repair and regeneration, immune response, and metastasis. Cells migrate in response to chemical or mechanical signals generated by specific organs or tissues. The overall mechanism includes three steps - polarization, protrusion, and release. Polarization involves the formation of a distinct cell front and rear, which determines the direction of movement.
01:35Cancer Cell Migration through Invadopodia
Invadosome is a broad category of cell surface structures with proteolytic activity that degrades the extracellular matrix (ECM). Invadosomes are present in normal cell types, including macrophages, endothelial cells, and neurons, as well as tumor cells. Although the macrophage podosomes and tumor cell invadopodia are classified as invadosomes, they have different structures, molecular pathways, and functions. Podosomes are short structures that last for a few minutes. However, invadopodia can...
01:32Cytoskeletal Coordination in Cell Migration
A migrating cell changes its shape during the cyclic events of attachment and detachment from the substratum and repositions the cell organelles correspondingly. These complex events are orchestrated by the dynamic cytoskeletal network comprising actin filaments, intermediate filaments, and microtubules. Cytoskeletal crosstalk — the direct and indirect communication between the different components — is crucial for this coordination. Direct communication involves various linker proteins that...
01:23Renewal of Intestinal Stem Cells
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 goblet,...
01:22Role of Ephrin-Eph Signalling in Intestinal Stem Cell Renewal
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.
