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.

Scientists develop CRISPRainbow to study genome structure in real time

CRISPRainbow, a new technology using CRISPR/Cas9 developed by scientists at UMass Medical School, allows researchers to tag and track up to seven different genomic locations in live cells. This labeling system, details of which were published in Nature Biotechnology, will be an invaluable tool for studying the structure of the genome in real time.

Distribution of c-Myc protein during asymmetric cell division influences fate, roles of activated T cells

The fates of immune cells can be decided at the initial division of a cell. Researchers at St. Jude Children's Research Hospital have discovered that the production of daughter cells with different roles in the immune system is driven by the lopsided distribution of the signaling protein c-Myc. Nudging c-Myc in one direction or the other could make vaccines more effective or advance immunotherapies for cancer treatment. The research appears online today in the scientific journal Nature.

Scientists successfully turn off misbehaving protein that fuels growth of triple-negative breast cancer

Working with human breast cancer cells, a team of scientists from Ann & Robert H. Lurie Children's Hospital of Chicago have successfully turned off a misbehaving protein that fuels the growth of a particularly aggressive, drug-resistant form of the disease known as triple-negative breast cancer.

Study may help identify unborn children at higher risk for birth defects

Researchers at the University of Toronto have discovered a novel function performed by the breast cancer 1 protein (BRCA1), which regulates DNA repair. Well known for the role it plays in breast and ovarian cancer, this study revealed that the BRCA1 protein actually plays a much broader biological role, particularly in protecting the developing embryo from the damaging effects of reactive oxygen species (ROS).

Low-oxygen conditions spur growth of breast cancer stem cells

Working with human breast cancer cells and mice, scientists at The Johns Hopkins University say new experiments explain how certain cancer stem cells thrive in low oxygen conditions. Proliferation of such cells, which tend to resist chemotherapy and help tumors spread, are considered a major roadblock to successful cancer treatment.

Findings could help explain origin of type 2 diabetes in children of obese mothers

A new study led by researchers at The Saban Research Institute of Children's Hospital Los Angeles reports that the presence of leptin - a hormone secreted by fat cells that is critical to maintaining energy balance in the body -- inhibits the prenatal development of neuronal connections between the brain and pancreas. The findings could help explain the origin of type 2 diabetes, particularly in children of obese mothers.

Study uncovers role of small RNAs in fine-tuning egg development

All multicellular organisms that reproduce sexually rely on eggs to support early life. Researchers at University of California, San Diego School of Medicine and Ludwig Cancer Research used the tiny roundworm C. elegans as a model to better understand how eggs enable embryonic development, using only the materials already present in them.

Mothers give offspring a head start in life

Thank your mothers: A research collaboration between UC Santa Barbara and L'École Normale Supérieure in Paris has proven that deterministic maternal effects can give offspring a better start on life.

Study shows new RNA letter as regulatory key to control gene expression

DNA, RNA, protein -- the end. Or is it? Until recently, the pattern used to encode genetic information into our cells was considered to be relatively straightforward: four letters (A,G,C,T) for DNA and four (A,G,C,U) for RNA. This equation, however, turned out to be oversimplified -- RNA was holding out.

Researchers discover factor that controls embryonic stem cell development

After a gestation period of around ten months, fawns are born in early summer - when the weather is warm and food is plentiful for the mother. Six months would actually be enough for the embryo's development, but then offspring from mating in the later portion of summer would be born in winter.

Variations in Tie2 gene play significant role in patient responses to infections

Major infections such as influenza and bacterial sepsis kill millions of people each year, often resulting fro dangerous complications that impair the body's blood vessels. But the reasons why some patients experience these dramatic responses to infections -- and others don't -- have been unclear.

Duchenne muscular dystrophy: direct effect on muscle stem cells? An interview with Dr Rudnicki

For twenty years, it has been understood that dystrophin is expressed in differentiated muscle fibers where it is part of a protein complex that crosses the membrane and connects the extracellular matrix to the actin network inside the cell to provide structural integrity.

Study reveals fetal origin for social and repetitive behavior deficits

Fetal development has been known to play an important role in social interaction, a fundamental behavior found in nearly all organisms, and later adult social behaviors. Autism, a highly heritable neurodevelopment disorder that causes difficulties with social interactions, has been postulated to be caused by neuron overgrowth in the prenatal period, although the precise timing and cause of this overgrowth has been unknown.

Rockefeller University researchers identify new mechanism involved in early stem cell development

Stem cells work throughout our lives as a sort of handyman, repairing damaged tissues and renewing some normal ones, like the skin we shed. Scientists have come to understand much about how stem cells function when we are adults, but less is known about where these stem cells come from to begin with, as an embryo is developing.

Researchers discover molecular target for DNA repair defects behind Fanconi anemia

Researchers have identified a molecular target and experimental treatment strategy for DNA repair defects behind Fanconi anemia – a complex genetic disorder responsible for birth anomalies, organ damage, anemia and cancer.

DNA-binding protein acts like genetic traffic signal to orchestrate early stage embryonic development

New research by UC San Francisco stem cell biologists has revealed that a DNA-binding protein called Foxd3 acts like a genetic traffic signal, holding that ball of undifferentiated cells in a state of readiness for its great transformation in the third week of development.

New classification of coronary congenital diseases helps surgeons identify secondary defects

A new classification of coronary congenital diseases is set to help surgeons identify secondary defects in the operating theatre. The scheme is outlined in a novel European Society of Cardiology position paper published today in Cardiovascular Research.1 Clinical cardiologists will also know what to look for on cardiovascular images.

Wnt5a protein acts on tumor-surface proteins to accelerate spread of CLL cells

Building upon previous research, scientists at University of California, San Diego School of Medicine and UC San Diego Moores Cancer report that a protein called Wnt5a acts on a pair of tumor-surface proteins, called ROR1 and ROR2, to accelerate the proliferation and spread of chronic lymphocytic leukemia (CLL) cells, the most common form of blood cancer in adults.

Endocrine-disrupting chemicals pose threat to male reproductive health

The birth rate is declining in all industrialised countries, and socioeconomic factors and women's age are not solely to blame. Male reproductive health and environmental factors are also significant, as concluded in a new scientific review article.

Scientists discover genetic causes of Goldenhar syndrome

Some children are born with cleft palates and, of those children, some have an asymmetrical face and a malformed ear. A team of scientists led by Berlin-based researcher Enno Klußmann of the Max Delbrück Center for Molecular Medicine has taken an important step towards discovering the genetic causes of this condition, known as Goldenhar syndrome.
