Neurogenesis and Regeneration of Nervous Tissue

Neurogenesis and Regeneration of Nervous Tissue

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...

Neuroplasticity

Neuroplasticity

Neuroplasticity reflects the brain's remarkable capacity to adapt and evolve, responding dynamically to learning, experiences, or injury by reorganizing its neural circuitry. This reorganization involves creating new neural connections and refining old ones through a series of biological processes that contribute to the brain's lifelong development and adaptability.

Population Growth

Population Growth

Population size is dynamic, increasing with birth rates and immigration, and decreasing with death rates and emigration. In ideal conditions with unlimited resources, populations can increase exponentially, which plots as a J-shaped growth rate curve of population size against time. This type of curve is characteristic of newly-introduced invasive species, or populations that have suffered catastrophic declines and are rebounding.However, realistic environmental conditions limit the number of...

What is Population Genetics?

What is Population Genetics?

A population is composed of members of the same species that simultaneously live and interact in the same area. When individuals in a population breed, they pass down their genes to their offspring. Many of these genes are polymorphic, meaning that they occur in multiple variants. Such variations of a gene are referred to as alleles. The collective set of all the alleles within a population is known as the gene pool.While some alleles of a given gene might be observed commonly, other variants...

Neural Circuits

Neural Circuits

Neural circuits and neuronal pools are two of the main structures found in the nervous system. Neural circuits are networks of neurons that work together to carry out a specific task or process. They consist of interconnected neurons and glial cells, which provide structural and metabolic support.
Neuronal pools are collections of nerve cells with similar functions and interact through chemical and electrical signals. These pools include both interneurons (the central neural circuit nodes that...

Background:

Neural stem cells (NSCs) self-renew and differentiate.
Progenitor cells are key intermediates in neurogenesis.
Precise regulation of these populations is vital for brain development and function.

Purpose of the Study:

To investigate the role of Epidermal Growth Factor Receptor (EGFR) and Notch 1 signaling in regulating neural stem and progenitor cell populations.
To elucidate the interplay between EGFR and Notch 1 pathways in neurogenesis.

Main Methods:

Utilized in vitro models of neurogenesis.
Employed genetic manipulation to alter EGFR and Notch 1 signaling.
Quantified neural stem and progenitor cell numbers using flow cytometry and immunocytochemistry.

Main Results:

EGFR signaling promotes neural stem cell proliferation.
Notch 1 signaling promotes progenitor cell differentiation.
The combined action of EGFR and Notch 1 pathways maintains a balance between stem and progenitor cells.

Conclusions:

The EGFR–Notch 1 pathway interaction is a critical mechanism for balancing neural stem and progenitor cell pools.
Dysregulation of this pathway may contribute to developmental brain disorders.
