Neurogenesis and Regeneration of Nervous Tissue01:15

Neurogenesis and Regeneration of Nervous Tissue

2.0K
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...

Somatic to iPS Cell Reprogramming

2.9K
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...

Nervous Tissue: Myelin01:25

Nervous Tissue: Myelin

10.2K
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...

Methods of Nuclear Reprogramming

2.3K
Nuclear reprogramming is a process of transforming one cell type into an unrelated cell type by epigenetic changes that alter the cell’s original gene expression pattern. Such epigenetic changes force cells to express a different set of genes, which play a significant role in inducing transformation into other cell types. Nuclear reprogramming offers applications in reproductive cloning for livestock propagation and regenerative medicine — developing patient-specific cells for...

Differentiation of Common Myeloid Progenitor Cells01:15

Differentiation of Common Myeloid Progenitor Cells

4.2K
Common myeloid progenitors (CMPs) are oligopotent cells that can differentiate into granulocytes and macrophages. Granulocytes and macrophages are essential for protecting the body against bacterial, viral, or fungal infections. They migrate from the bone marrow into the circulating blood to reach specific tissue sites where they differentiate and help in immune surveillance. However, they survive only for a few days and must be continuously made available to the organism to maintain a robust...

Area of Science:

  • Neuroscience
  • Regenerative Medicine
  • Cell Biology

Background:

  • Demyelinating diseases like multiple sclerosis (MS) cause significant disability and healthcare costs due to myelin loss in the central nervous system.
  • Current immunosuppression therapies for MS have limited efficacy, highlighting the need for strategies promoting myelin repair.
  • The microenvironment in MS lesions inhibits oligodendrocyte precursor cell (OPC) differentiation, hindering natural remyelination.

Purpose of the Study:

  • To review the plasticity of OPCs regarding their origins, distribution, and differentiation potential in normal and injured brains.
  • To explore recent discoveries of intrinsic and extrinsic factors, including small molecules, that regulate OPC specification and differentiation.
  • To discuss the therapeutic potential of activating neural progenitor cells and reprogramming differentiated cells for remyelination in MS.

Main Methods:

  • Literature review focusing on oligodendrocyte precursor cell (OPC) biology.
  • Analysis of studies on factors influencing OPC differentiation and plasticity.
  • Examination of therapeutic strategies for remyelination and neuroprotection.

Main Results:

  • OPCs exhibit remarkable plasticity, capable of differentiating into various cell lineages under specific conditions.
  • Both intrinsic and extrinsic factors, as well as small molecule compounds, significantly control OPC fate.
  • Understanding these mechanisms is crucial for developing novel regenerative therapies for demyelinating diseases.

Conclusions:

  • Targeting OPCs offers a promising therapeutic avenue for promoting remyelination and neuroprotection in MS.
  • Activating OPCs' regenerative potential or employing cell replacement strategies could revolutionize treatment for demyelinating diseases.
  • Further research into OPC plasticity and differentiation control is essential for advancing myelin repair therapies.
