Summary

Human brain development occurs in three stages, driven by self-renewing neural stem cells. This study re-evaluates key markers and concepts in human brain development, including glial fibrillary acidic protein.

Area of Science:

  • Neuroscience
  • Developmental Biology
  • Cell Biology

Background:

  • Human brain development involves complex architectural changes.
  • Matrix cell theory proposes the existence of neural stem cells with self-renewing and multipotent capabilities in the developing brain.
  • Understanding these processes is crucial for comprehending neurodevelopmental disorders.

Purpose of the Study:

  • To discuss architectural changes in the developing human brain based on matrix cell theory.
  • To re-evaluate the existence and role of glial fibrillary acidic protein in the developing human brain.
  • To critically examine commonly used terms like "radial glial fiber" and "subventricular zone".

Main Methods:

  • Review of existing literature on human brain development.

  • Immunohistochemical analysis of various markers during brain development.
  • Categorization of differentiation lineages based on marker distribution.

    • Main Results:

    • Neural stem cells/matrix cells with self-renewing and multipotency are confirmed in the developing human brain in vivo.
    • Human brain development is characterized by three distinct, time-regulated stages of cell differentiation.
    • Re-evaluation of glial fibrillary acidic protein distribution and the concepts of "radial glial fiber" and "subventricular zone".

    Conclusions:

    • Matrix cell theory provides a framework for understanding human brain development.
    • Cell differentiation is a precisely time-regulated process during human brain development.
    • A revised understanding of key cellular markers and anatomical zones is proposed.
