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.
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.
It happens in the first hours after fertilization: The cells of the early embryo begin to independently produce proteins, the building blocks for cells and organs.
Hereditary diseases, along with cancers and cardiovascular diseases, may be linked to genomic imprinting.
Multiple changes in brain cells during the first month of embryonic development may contribute to schizophrenia later in life, according to a new study by Weill Cornell Medicine investigators.
Researchers at the University of Bonn have developed a method to generate embryo-like cell complexes from the stem cells of mice. The method provides new insights into embryonic development. In the medium term, it might also be suitable for developing tests for substances that could be harmful to fertility. The study is published in the prestigious journal Nature Communications.
A group of scientists headed by the Agency for Science, Technology and Research’s (A*STAR) recently identified a new gene.
A group of researchers identified how a minor disturbance in the activation mechanism of this gene triggers the origin of clubfoot, a common foot malformation.
