Summary
Neural crest development relies on precise signaling interactions. Coordinated BMP and Wnt pathways, alongside tissue communication, are crucial for specifying neural crest progenitor cells.
Area of Science:
- Developmental biology
- Cell biology
- Molecular biology
Background:
- The neural crest is a transient embryonic cell population crucial for vertebrate development.
- Neural crest cells originate from the neural plate border, requiring coordinated signaling for their specification.
Purpose of the Study:
- To review the formation of the neural plate border (NPB) territory.
- To emphasize the critical roles of BMP and Wnt signaling pathways in neural crest specification.
Main Methods:
- Review of existing literature on neural crest development.
- Analysis of signaling molecule interactions (BMP, Wnt, FGF) and their antagonists.
- Focus on tissue communication in the context of NPB formation.
Main Results:
- Neural plate border specification is dependent on interactions with adjacent tissues.
- A precise interplay of BMP and Wnt signaling is essential for defining the prospective neural crest.
- Signaling molecules from surrounding tissues induce specific gene expression in the NPB.
Conclusions:
- Coordinated BMP and Wnt signaling are indispensable for neural crest formation.
- Effective communication between embryonic tissues is vital for specifying neural crest progenitor cells.

03:14Notch Signaling Pathway
6.7K
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...

01:30Neurulation
46.8K
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...

02:33Hedgehog Signaling Pathway
10.3K
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...

01:19Interactions Between Signaling Pathways
7.5K
Signaling cascades usually lack linearity. Multiple pathways interact and regulate one another, allowing cells to integrate and respond to diverse environmental stimuli.
Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...

01:51Determination
21.2K
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...

01:23Overview of Cell Signaling
25.5K
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...
