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.

Newly discovered molecular process could speed up recovery from nerve injuries

Twenty million Americans suffer from peripheral nerve injuries, which can be caused by traumas such as combat wounds and motorcycle crashes as well as medical disorders including diabetes.

Leukemia drug appears to be effective in treating deadly pediatric brain tumor

A drug used to treat chronic myeloid leukemia appears to be more effective at stopping a type of medulloblastoma in mouse models than existing treatments for the deadly pediatric brain tumor, reports a multi-institutional team led by researchers at Skaggs School of Pharmacy and Pharmaceutical Sciences at University of California San Diego.

Study provides new insight into how cells maintain their identity

In the body's cells, some proteins are of vital importance as to which genes are active or turned off. Now, researchers from the University of Copenhagen and the Memorial Sloan Kettering Cancer Center have discovered which proteins are necessary in order to maintain the proper genetic regulation.

Scientists pinpoint cause of fatal genetic disorder in children

Scientists at Washington University School of Medicine in St. Louis appear to have solved a decades-long mystery regarding the precise biochemical pathway leading to a fatal genetic disorder in children that results in seizures, developmental regression and death, usually around age 3.

Cure for Rett Syndrome a step closer as scientists successfully reactivate 'back-up’ genes

A team headed by Vincent Pasque at his Lab at KU Leuven alongside researchers from the Jean-Christophe Marine lab and the Edith Heard lab have made a significant step towards developing a treatment for Rett syndrome and other X chromosome linked disorders.

Forbidden fruit: Scientists venture into “embryoid” manufacturing

After working on stem cells for several years, scientists have now announced that they have found a way to synthesize structures that look like very primitive human embryos. While some hailed the discovery, others questioned the ethical basis of manufacturing synthetic humans.

Study reshapes the understanding of telomerase's function in normal cells

New research from the University of Maryland and the National Institutes of Health reveals a new role for the enzyme telomerase.

Protein present in telomeres shows global action on genome which influences pleuripotency

Pluripotent cells can give rise to all cells of the body, a power that researchers are eager to control because it opens the door to regenerative medicine and organ culture for transplants.

Scientists identify group of proteins for repair of nerve fibers

Scientists at the German Center for Neurodegenerative Diseases have identified a group of proteins that help to regenerate damaged nerve cells. Their findings are reported in the journal Neuron.

Study forms basis for therapeutic strategies to combat cancers caused by HMGA1a

The researchers led by Professor Raphael Stoll therefore expect their results to form a basis for future therapeutic strategies to combat cancers caused by HMGA1a.

Mechanical forces regulate cellular behavior during embryonic development of the brain

A new study coordinated by the Research Group in Developmental Biology at UPF shows that during the embryonic development of the brain, the cells that are between adjacent segments detect the mechanical forces generated during morphogenesis to regulate the balance between progenitor stem cells and differentiated neurons.

Folic acid supplementation mitigates risk of neural tube defects linked to HIV drug

Dolutegravir is a preferred medication for treating HIV infection, but it recently has been linked to a 6- to 9-fold increase in the risk for neural tube defects among babies born to mothers receiving the drug during early gestation.

Ancient epigenetic change deactivates some genes linked to cancer

An epigenetic change, a form of DNA control, that deactivates some genes linked to cancer late in human development has been conserved for more than 400 million years, new research led by the Garvan Institute of Medical Research suggests.

RNA-binding protein SRSF3 appears to be key factor for proper heart contraction, survival

A team of scientists led by Dr Enrique Lara Pezzi at the Centro Nacional de Investigaciones Cardiovasculares has identified the RNA-binding protein SRSF3 as an essential factor for proper heart contraction and survival.

Researcher finds possible strategy for killing cancer cells in children

In Belgium, there are 70,000 new adult cases of cancer every year, compared to 350 in children. Owing to lack of interest from pharmaceutical groups, treatments for pediatric cancers are developing much less rapidly than those for adults.

Healthy mice pups can be produced from sperm without short RNA chains

Scientists from the University of Bath are challenging the claims of two high profile papers from 2018 which reported that in the mouse, RNA has to be added to sperm for them to be fully fertile.

New 3D model shines light on key aspects of early development

From a biological standpoint, the earliest stages of life are the most mysterious. A developing human embryo undergoes a flurry of rapid changes, and these changes are exceedingly difficult to study because they transpire within the confines of a womb.

UK government to consider fortifying flour with folic acid to combat neural tube defects

A 12-week consultation has been launched to discuss whether folic acid should be added to flour in the UK.
