Summary
The neural plate border (NPB) in embryonic development contains multipotent cells. Signaling pathways like Wnt and BMP are crucial for NPB stem cell differentiation and neural crest formation.
Area of Science:
- Developmental biology
- Cellular and molecular biology
Background:
- The vertebrate embryonic epiblast differentiates into neural and superficial ectoderm.
- The neural plate border (NPB) is a transitional zone between these ectodermal layers, housing multipotent progenitor cells.
Purpose of the Study:
- To review current knowledge on neural plate border formation.
- To emphasize the critical role of signaling pathway interactions in neural crest cell fate determination.
Main Methods:
- Literature review of signaling pathways (Wnt, FGF, BMP, Notch).
- Analysis of gene expression and regulation.
- Examination of tissue crosstalk in early human embryonic development.
Main Results:
- Cellular heterogeneity within the NPB leads to diverse differentiated cell types.
- Multiple signaling pathways, including BMP and Wnt cascades, are essential for NPB stem cell determination and differentiation.
- Precise temporospatial coordination of cellular and tissue interactions is vital for defining neural crest fate.
Conclusions:
- Understanding the intricate interplay of signaling pathways and gene regulation is key to comprehending neural plate border development.
- Tissue crosstalk significantly influences the differentiation of neural crest cells from ectodermal progenitors in early human embryos.

01:30Neurulation
41.8K
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...

01:51Determination
18.4K
During embryogenesis, cells become progressively committed to different fates through a two-step process: specification followed by determination. Specification is demonstrated by removing a segment of an early embryo, “neutrally” culturing the tissue in vitro—for example, in a petri dish with simple medium—and then observing the derivatives. If the cultured region gives rise to cell types that it would normally generate in the embryo, this means that it is specified. In...

03:14Notch Signaling Pathway
4.2K
The Notch signaling pathway is a major intracellular signaling pathway that is highly conserved over a broad spectrum of metazoan species. It stands unique from other intracellular signaling mechanisms in animals because notch protein itself acts as the receptor as well as the primary signaling molecule.
The Notch gene came into the limelight in 1914 after the discovery that its mutation in Drosophila melanogaster leads to a serrated (or "notched") wing margin phenotype. It was not...

02:33Hedgehog Signaling Pathway
7.3K
The Hedgehog gene (Hh) was first discovered due to its control of the growth of disorganized, hair-like bristles phenotype in Drosophila, much like hedgehog spines. Hh plays a crucial role in the development of organs and the maintenance of homeostasis in both invertebrates and vertebrates. However, while Drosophila has only one Hh protein, mammals have multiple functional Hedgehog proteins - Sonic (Shh), Desert (Dhh), and Indian Hedgehog (Ihh). All of these homologous proteins have adapted to...

01:31Immunoglobulin-like Cell Adhesion Molecules
3.2K
Immunoglobulin-like cell adhesion molecules or Ig-CAMs are a versatile group of cell surface glycoproteins belonging to the immunoglobulin protein superfamily. Ig-CAMs possess the characteristic immunoglobulin protein domains and other domains such as the fibronectin type III domain. The Ig domains are glycosylated to varying degrees in different Ig-CAMs.
Ig-CAMs exhibit either homophilic binding (to other Ig-CAMs) or heterophilic binding (to other ligands such as integrins). While most Ig-CAMs...

20.2K
Despite the protective membrane that separates a cell from the environment, cells need the ability to detect and respond to environmental changes. Additionally, cells often need to communicate with one another. Unicellular and multicellular organisms use a variety of cell signaling mechanisms to communicate with the environment.
Cells respond to many types of information, often through receptor proteins positioned on the membrane. For example, skin cells respond to and transmit touch...
