Neurogenesis and Regeneration of Nervous Tissue01:15

Neurogenesis and Regeneration of Nervous Tissue

1.6K
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...

Nervous Tissue: Myelin

5.4K
The myelin sheath is a multilayered lipid and protein covering that insulates the axon of a neuron, enhancing the speed of nerve impulse conduction. Axons without this sheath are referred to as unmyelinated. Two types of neuroglia, Schwann cells in the peripheral nervous system (PNS) and oligodendrocytes in the central nervous system (CNS) are responsible for producing myelin sheaths.
Schwann cells begin to form myelin sheaths around axons during fetal development. They wrap around a small...

Nervous Tissue: Glial Cells

6.5K
Glia, or neuroglia, are vital support cells that assist neurons in their functions. The term "glia" originates from the Greek word for "glue," reflecting their role in holding the nervous system together. These cells can be categorized into six types: four in the central nervous system (CNS) and two in the peripheral nervous system (PNS).
The CNS glial cell includes the astrocytes, the oligodendrocytes, the microglia, and the ependymal cells.
Astrocytes are star-shaped glial...

Area of Science:

  • Neuroscience
  • Cell Biology
  • Regenerative Medicine

Background:

  • Schwann cells (SCs) are the main glial cells in the Peripheral Nervous System (PNS), essential for axonal insulation, protection, and nutrition.
  • Advances in neuroscience highlight SCs' roles in disease pathogenesis and potential therapeutic applications for neurological disorders.
  • SCs produce various factors like cytokines, growth factors, and extracellular vesicles that aid neuronal survival and axonal regeneration.

Purpose of the Study:

  • To explore therapeutic strategies involving Schwann cells (SCs) and their derivatives for neurological disorders.
  • To review the potential of SC-based therapies for nerve injury repair and peripheral neuropathies.
  • To identify future directions for enhancing SC-based treatments.

Main Methods:

  • Review of preclinical and clinical data on Schwann cell (SC) therapy.
  • Analysis of SC-derived factors and exosomes for therapeutic potential.
  • Examination of genetic engineering and in vivo modification strategies for SCs.

Main Results:

  • Schwann cells (SCs) and their derived factors show viability as cell therapy for nerve repair and peripheral neuropathies.
  • Preclinical and clinical data support SC-based approaches for reconstructing tissue microenvironments and promoting nerve recovery.
  • Genetic engineering of SCs is progressing, with ongoing preclinical and clinical trials.

Conclusions:

  • Targeting, modifying, and replacing Schwann cells (SCs), along with utilizing SC-derived products, represent novel therapeutic avenues for neuropathological conditions.
  • Improving methods to obtain 'repair' Schwann cells (SCs) and their products is critical for future clinical success.
  • Further development of in vivo therapeutic approaches to modulate SC survival and function is urgently needed.
