Gastrulation

Gastrulation

Gastrulation establishes the three primary tissues of an embryo: the ectoderm, mesoderm, and endoderm. This developmental process relies on a series of intricate cellular movements, which in humans transforms a flat, “bilaminar disc” composed of two cell sheets into a three-tiered structure. In the resulting embryo, the endoderm serves as the bottom layer, and stacked directly above it is the intermediate mesoderm, and then the uppermost ectoderm. Respectively, these tissue strata...

Cleavage and Blastulation

Cleavage and Blastulation

After a large-single-celled zygote is produced via fertilization, the process of cleavage occurs while zygotes travel through the uterine tube. Cleavage is a mitotic cell division that does not result in growth. With each round of successive cell division, daughter cells get increasingly smaller.

Hedgehog Signaling Pathway

Hedgehog Signaling Pathway

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...

Area of Science:

Developmental Biology
Molecular Biology
Genetics

Background:

Embryonic development relies on precise genetic programming for timely progression.
Gene expression oscillations are a key mechanism for controlling developmental timing.
Understanding these oscillations is crucial for deciphering developmental processes.

Purpose of the Study:

To review how gene expression oscillations encode temporal information in vertebrate embryonic development.
To examine oscillations in somitogenesis, neurogenesis, myogenesis, and pancreas development.
To compare spatial and temporal expression patterns of key regulatory genes.

Main Methods:

Review of existing literature on gene expression oscillations in embryonic development.
Analysis of gene expression patterns (synchronous/asynchronous, timescales) of Hes/Her genes and targets.
Summarization of experimental evidence for the functional roles of these oscillations.

Main Results:

Gene expression oscillations play varied roles, controlling somite formation period and stem cell differentiation.
Similarities and differences in spatial and temporal expression patterns of Hes/Her genes were identified across tissues.
Experimental data support the functional significance of these oscillations in development.

Conclusions:

Gene expression oscillations are fundamental for temporal control in vertebrate embryonic development.
These oscillations exhibit context-dependent functions, impacting distinct developmental events.
Further research is needed to address outstanding questions regarding oscillation mechanisms and roles.
