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.
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.
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.
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.
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.
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.
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.
According to the latest research, medical and life science scientists will benefit from the most detailed atlas of zebrafish genetic data available.
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.
Coral reef fish breed more successfully if motorboat noise is reduced, new research shows.
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.
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.
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.
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.
The pancreas is a key metabolic regulator. When pancreatic beta cells cease producing enough insulin, blood sugar levels rise dangerously — a phenomenon known as hyperglycemia — thus triggering diabetes.
Scientists declared the invention of a transgene-free and manageable method to transform pluripotent stem cells into bona fide 8-cell totipotent embryo-like cells.
For years, scientists have been unable to create a patient’s blood cells to cure blood illnesses, but a recently implemented federal funding might help IOWA State University researchers take important steps toward making that prospect a reality.
The brain is composed of billions of neurons-; vulnerable cells that require a protective environment to function properly.
Scientists have mapped out the key molecular changes that orchestrate how embryonic mouse cells differentiate into the diverse cell types that will ultimately form all the different tissues and organs of the adult animal.
Intestinal cells can change specializations during their lives. The BMP signaling pathway – an important communication mechanism between cells – appears to be the driver of these changes.
The zebrafish is an important model organism for studying things like genetic diseases. A regulatory map of its genome has been successfully created using high-throughput experiments and AI methods, a team led by Uwe Ohler now reports in Cell Genomics and Nature Machine Intelligence.
