Neurogenesis and Regeneration of Nervous Tissue01:15

Neurogenesis and Regeneration of Nervous Tissue

1.9K
In the CNS, neurogenesis, the birth of new neurons from stem cells, is limited to the hippocampus in adults. In other regions of the brain and spinal cord, neurogenesis is almost non-existent due to inhibitory influences from neuroglia, especially oligodendrocytes, and the absence of growth-stimulating cues. The myelin produced by oligodendrocytes in the CNS inhibits neuronal regeneration. Furthermore, astrocytes proliferate rapidly after neuronal damage, forming scar tissue that physically...

Liver Regeneration01:24

Liver Regeneration

4.6K
The liver is an important organ in vertebrates that plays an essential role in metabolism. It is also responsible for storing and redistributing nutrients such as carbohydrates, fats, and vitamins in the body. Additionally, the liver releases bile salts which are critical for digesting food and eliminating toxic metabolites from the body.
Cells of Liver
The liver comprises four major types of cells— hepatocytes, stellate, Kupffer, and sinusoidal endothelial cells. The hepatocytes are...

Renewal of Intestinal Stem Cells01:23

Renewal of Intestinal Stem Cells

3.5K
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...

Tissue Renewal without Stem Cells01:23

Tissue Renewal without Stem Cells

2.2K
After cellular or tissue damage, the resident stem cells present in the human body can locally repair and regenerate the damaged tissue or organ. However, even though some tissues do not have stem cells, they can repair and regenerate with the help of pre-existing cells. For example, beta cells of the pancreas and hepatocytes of the liver can divide to renew and regenerate the tissue. Here, both cell division and cell death are well regulated by homeostasis.
However, failure of such a system...

Stem Cell Therapy for Tissue Regeneration01:21

Stem Cell Therapy for Tissue Regeneration

4.8K
Stem cell therapy is a method used in regenerative medicine to repair and restore function to damaged tissues and organs. Stem cells have the potential to proliferate and differentiate into various tissue types, making them ideal candidates for tissue regeneration. For example, hematopoietic stem cell transplants are commonly used in blood cancer treatment to replenish damaged bone marrow and restore healthy blood cells.
Types of Stem Cells used in Stem Cell Therapy
The two main cell...

Whole Body Regeneration01:33

Whole Body Regeneration

4.3K
Regeneration is the process of restoring injured or lost tissues, organs, or body parts. While simpler organisms generally show greater ability to regenerate their whole body, few complex animals show similarly exceptional regeneration. For example, planarian flatworms have a unique regenerative potential making them a popular study organism among biologists to understand the mechanisms of whole body regeneration. Other organisms, such as hydra, also show extreme regeneration potential;...

Summary

Neurogenesis occurs in the mammalian brain, but cannot fully repair damage from neurological diseases. New research explores stem cell niches in brain-adjacent tissues, like the meninges, for potential therapeutic applications.

Area of Science:

  • Neuroscience
  • Stem Cell Biology
  • Regenerative Medicine

Background:

  • Neurogenesis is confirmed in mammalian brains, including humans.
  • However, endogenous neurogenesis is insufficient to repair significant brain tissue loss from conditions like stroke, trauma, or neurodegenerative diseases.
  • Neural stem cell niches extend beyond traditional areas to include meninges and choroid plexus.

Purpose of the Study:

  • To review the relationship between neural stem cells and interstitial cells, particularly telocytes.
  • To explore the neurogenic potential of tissues adjacent to the brain (juxtacerebral tissues).

Main Methods:

  • Literature review of recent evidence on neural stem cell niches.
  • Analysis of the interaction between neural stem cells and telocytes.
  • Examination of neurogenesis in juxtacerebral tissues.

Main Results:

  • Neural stem cell niches are found in extra-ventricular locations, including meninges and choroid plexus.
  • A significant relationship exists between neural stem cells and interstitial cells like telocytes.
  • Juxtacerebral tissues possess demonstrable neurogenic potential.

Conclusions:

  • The discovery of neural stem cell niches in juxtacerebral tissues offers new avenues for neurological repair.
  • Understanding the role of telocytes in supporting neural stem cells is crucial for future therapeutic strategies.
  • Targeting these extra-cerebral stem cell niches may provide novel treatments for brain damage.
