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.

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.

Scientists reveal the origins and provide a detailed ID card of pancreatic endocrine stem cells

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.

New BGI research lays groundwork for organ regeneration

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.

ISU researchers receive major funding to go forward on blood stem cells research

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.

Researchers develop an antibody as a tool for opening the blood-brain barrier

The brain is composed of billions of neurons-; vulnerable cells that require a protective environment to function properly.

New map tracks cellular trajectories across mouse embryogenensis

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 cell changes are driven by the BMP signaling pathway, study finds

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.

Researchers create a regulatory map of zebrafish genome

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.

Researchers elucidate how early embryo cells begin to independently produce proteins

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.
