Renewal of Intestinal Stem Cells01:23

Renewal of Intestinal Stem Cells

3.3K
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...

Introduction to Nuclear Reprogramming

2.3K
Nuclear reprogramming is the process of switching gene expression of one cell type to that of another cell type, usually from a differentiated cell state to an undifferentiated cell state. Differentiation occurs during processes such as development and morphogenesis, tissue regeneration, and malignancy. Cells can also be artificially induced to reprogram their gene expression by techniques such as nuclear transfer, induced pluripotency, and cell fusion. Such techniques have many applications in...

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...

Somatic to iPS Cell Reprogramming01:29

Somatic to iPS Cell Reprogramming

2.7K
Reprogramming alters the gene expression in somatic cells, transforming them into induced pluripotent stem (iPS) cells over several generations. Scientists can reprogram cells by introducing genes for four transcription factors—Oct4, Sox2, Klf4, and c-Myc (OSKM) by viral or non-viral methods. These factors are also known as Yamanaka factors after Shinya Yamanaka, who first generated iPS cells using mouse skin cells. Yamanaka was awarded the Nobel Prize in Physiology or Medicine in 2012...

Area of Science:

  • Gastroenterology
  • Stem Cell Biology
  • Regenerative Medicine

Background:

  • Intestinal organoids are valuable for disease modeling.
  • Current methods for generating intestinal tissues involve invasive biopsies and complex, expensive human pluripotent stem cell (hPSC) differentiation protocols.

Purpose of the Study:

  • To develop a more efficient and less invasive method for generating intestinal epithelial tissue.
  • To establish a direct conversion protocol for creating intestinal tissue from somatic cells.

Main Methods:

  • Direct reprogramming of mouse and human somatic cells into intestinal epithelial cells.
  • Characterization of the generated intestinal epithelial tissue for structural and functional integrity.

Main Results:

  • Successfully achieved direct conversion of somatic cells into robust intestinal epithelial tissue in both mice and humans.
  • The generated tissue exhibits characteristics of functional intestinal epithelium.

Conclusions:

  • Direct conversion offers a promising alternative to traditional organoid generation for intestinal disease modeling.
  • This approach reduces the need for invasive tissue harvesting and costly stem cell protocols, enhancing accessibility for research.
