Neurulation01:30

Neurulation

40.4K
Neurulation is the embryological process which forms the precursors of the central nervous system and occurs after gastrulation has established the three primary cell layers of the embryo: ectoderm, mesoderm, and endoderm. In humans, the majority of this system is formed via primary neurulation, in which the central portion of the ectoderm—originally appearing as a flat sheet of cells—folds upwards and inwards, sealing off to form a hollow neural tube. As development proceeds, the...

Cerebrum: Anatomical Overview I

5.8K
The main and largest component of the human brain is the cerebrum. The cerebrum consists of two main parts: the cerebral cortex, an outer layer with wrinkles or folds known as gyri and shallow grooves called sulci, and a deeper region beneath it. The cerebrum divides into two distinct hemispheres and contains five different lobes: the frontal, parietal, temporal, occipital, and insula. The central sulcus separates the frontal and parietal lobes and two functionally important gyri — the...

Cerebrum: Anatomical Overview II

5.0K
Each cerebral hemisphere can be divided into three main regions. The outermost region, the cerebral cortex, is a thin layer (2 to 4 millimeters thick) made up of gray matter, consisting of neuron cell bodies, dendrites, glial cells, and blood vessels. The middle region, or white matter, is primarily composed of myelinated nerve fibers organized into three types of large tracts: association fibers, commissures, and projection fibers. Association fibers connect different areas within the same...

Cerebrospinal Fluid01:21

Cerebrospinal Fluid

8.0K
Cerebrospinal fluid (CSF) is a colorless liquid that flows around the brain and the spinal cord, playing a vital role in the protection, support, and overall function of the central nervous system (CNS). CSF production, circulation, and absorption are tightly regulated processes essential for the brain and spinal cord to function properly.
CSF Production
CSF is produced mainly in the choroid plexus, a network of capillaries and ependymal cells located within the ventricular system of the brain....

Area of Science:

  • Neuroscience
  • Developmental Biology
  • Stem Cell Biology

Background:

  • Studying complex human brain disorders in model organisms is challenging.
  • There is a critical need for in vitro models of human brain development.

Purpose of the Study:

  • To develop a three-dimensional organoid culture system for modeling human brain development.
  • To investigate the recapitulation of human cortical development and disease phenotypes in vitro.

Main Methods:

  • Human pluripotent stem cells were differentiated into three-dimensional cerebral organoids.
  • RNA interference and patient-specific induced pluripotent stem cells were utilized.
  • Cerebral organoids were analyzed for developmental features and disease modeling.

Main Results:

  • Cerebral organoids developed discrete, interdependent brain regions, including a cerebral cortex with mature neuron subtypes.
  • Organoids recapitulated key features of human cortical development, such as progenitor zone organization and outer radial glial cells.
  • Patient-derived organoids modeled microcephaly, showing premature neuronal differentiation.

Conclusions:

  • Three-dimensional cerebral organoids serve as a viable in vitro model for human brain development.
  • This system effectively recapitulates both normal development and disease states of the human brain.
  • Cerebral organoids offer a powerful platform for studying complex neurological disorders.
