Transcellular Transport of Solutes01:23

Transcellular Transport of Solutes

4.8K
Transcellular transport of solutes is the movement of substances like monosaccharides and amino acids through polarized cells. This transport mechanism is primarily seen in epithelial and endothelial cells aided by membrane transport proteins such as channels and transporters. The tight junctions between these cells confine the membrane proteins to the two sides of the cell. The epithelial cells have distinct apical and basolateral domains. In contrast, the endothelial cells show the luminal...

Regulation of Hematopoietic Stem Cells01:01

Regulation of Hematopoietic Stem Cells

4.1K
All blood and immune cells are produced from the multipotent hematopoietic stem cells (HSCs) by the process of hematopoiesis. However, they all have a limited life span. In addition, many are depleted in immune surveillance or combatting an injury or infection. This makes blood one of the most regenerative tissues. Hematopoiesis helps replenish these blood and immune cells, restoring the body's normal functioning. However, overproduction of blood and immune cells can make them cancerous or...

Notch Signaling Pathway03:14

Notch Signaling Pathway

6.7K
The Notch signaling pathway is a major intracellular signaling pathway that is highly conserved over a broad spectrum of metazoan species. It stands unique from other intracellular signaling mechanisms in animals because notch protein itself acts as the receptor as well as the primary signaling molecule.
The Notch gene came into the limelight in 1914 after the discovery that its mutation in Drosophila melanogaster leads to a serrated (or "notched") wing margin phenotype. It was not...

Cadherins in Tissue Organization01:19

Cadherins in Tissue Organization

4.3K
The cadherins are a superfamily of cell adhesion molecules comprising over 180 variants, with specific tissues expressing a particular combination of cadherin types. Cadherins generally exhibit homophilic binding; i.e., cadherins on one cell bind to cadherins of the same or closely related type on another cell. Thus, cells of the same type have a specific affinity to bind to each other and sort themselves into clusters to form tissues.

Role Of Notch Signalling In Intestinal Stem Cell Renewal01:12

Role 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...

Summary
This summary is machine-generated.

Boundary cap cells (BCs) are versatile stem cells in the peripheral nervous system (PNS). These cells may be the origin of neurofibromas, particularly in neurofibromatosis type 1 (NF1).

Area of Science:

  • Neuroscience
  • Developmental Biology
  • Cell Biology

Background:

  • Peripheral glia exhibit broad plasticity during peripheral nervous system (PNS) development.
  • Neural crest-derived boundary cap cells (BCs) are identified as a multitask stem cell population within the developing PNS.

Purpose of the Study:

  • To review the origin and novel functions of BCs.
  • To discuss BC heterogeneity and their role in NF1 pathogenesis.

Main Methods:

  • Review of recent studies on BCs.
  • Analysis of BC progeny migration and glial contribution.
  • Examination of BCs in relation to neurofibroma development.

Main Results:

  • BC progeny migrate along nerves, forming glial components in nerve roots and skin terminals.
  • These sites are predisposed to neurofibroma development in neurofibromatosis type 1 (NF1).
  • BCs are considered potential cells of origin for NF1-related neurofibromas.

Conclusions:

  • BCs possess diverse functions and heterogeneity.
  • Understanding BCs is crucial for elucidating the pathogenesis of NF1.
