Embryonic Development News and Research

RSS

Embryonic development or embryogenesis is the process by which the embryo is formed and develops. It starts with the fertilization of the ovum, egg, which, after fertilization, is then called a zygote. The zygote undergoes rapid mitotic divisions, the formation of two exact genetic replicates of the original cell, with no significant growth (a process known as cleavage) and cellular differentiation, leading to development of an embryo.

Analyzing progenitor fate and dynamics long after embryonic development

According to Johns Hopkins Medicine researchers, they have devised a computer model called quantitative fate mapping that looks back in time to track the origin of cells in a fully grown organism.

3D imaging of shark embryos reveals evolution of pelvic fins

Curtin University researchers have revealed how the pelvic fins of fish such as sharks and chimaeras have evolved from their sudden appearance in the fossil record over 410 million years ago.

Gaining better insights into the origins of jaws by DNA sequence

At Uppsala University, a DNA sequence found in jawed vertebrates has been discovered and characterized by scientists. This includes sharks and humans, but it is absent in jawless vertebrates, like lampreys.

A gene’s function in embryonic development

An international study led by the medical school at the University of Bonn has discovered a gene that is crucial to the growth of the human embryo. Abnormalities of different organ systems may occur if it is changed.

Low protein synthesis in humans causes rare intestinal disease

According to a recent study, which will be published on November 1st, 2022, by Yun-Fei Li of Zhejiang University School of Medicine in Hangzhou, China, and colleagues, a decrease in protein synthesis in growing gut cells contributes to a rare genetic condition, and an affordable nutritional supplement could help reverse that decrease.

New guidelines to generate high-quality, well-structured organoids

Researchers have opened a new avenue for investigations of neurological development, disease, and therapies that cannot be undertaken in living people by employing stem cells to grow small brain-like structures in the lab.

Scientists uncover the robust mechanism used by insects

Researchers at IRB Barcelona, under the direction of Dr Marco Milan, have identified a very robust system that insects use for wing formation and regeneration.

Novel method maps all gene expression patterns to a single reference embryo

Years of work by Trinity College Dublin developmental biologists in collaboration with colleagues at the University of Edinburgh’s MRC Human Genetics Unit has resulted in an unparalleled resource that will help researchers assess how key genes control the differentiation of tissues and organs in developing embryos.

Parents transmit genetic and epigenetic information to their offspring

The knowledge of what can be inherited from parents and how their life experiences impact children could be completely rewritten if a fundamental finding concerning a factor driving healthy development in embryos were made.

Researchers get a complete atlas of zebrafish genetic data for biomedical research

According to the latest research, medical and life science scientists will benefit from the most detailed atlas of zebrafish genetic data available.

Differentiation protocol can develop safe and efficient pluripotent stem cell-based therapies for AMD

As we age, so do our eyes; most commonly, this involves changes to our vision and new glasses, but there are more severe forms of age-related eye problems.

'Traffic calming' helps coral reef fish to breed more successfully

Coral reef fish breed more successfully if motorboat noise is reduced, new research shows.

Researchers develop primitive endoderm stem cells in mice

RIKEN scientists have extracted and grown stem cells that give way to the mouse yolk sac for the first time in the laboratory, boosting the potential of generating mouse embryos from stem cells in the coming years.

Research sheds light on new options for organ cultivation in vitro

How do human cells organize themselves to give the organs their ultimate shape? The solution is morphogenesis, a collection of systems that controls their spatial distribution throughout embryonic development. In this sector, a team from the University of Geneva (UNIGE) recently discovered an unexpected discovery: when a tissue curves, the volume of the cells that makes it up grows rather than decreases.

New 3D in vitro model reveals the origins of human spine

The spinal column is the central supporting structure of the skeleton in all vertebrates. Not only does it provide a place for muscles to attach, it also protects the spinal cord and nerve roots. Defects in its development are known to cause rare hereditary diseases.

Researchers shed light on development and treatment of brain diseases

It is highly regulated what goes into the brain and what does not. The phagocytes that encapsulate the blood arteries in the brain and maintain the blood-brain barrier have been examined by researchers at the University of Freiburg’s Faculty of Medicine.
