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 breakthrough in stem cell and tissue engineering

The mechanism by which 'polycomb' proteins critical for embyronic stem cell function and fate are targeted to DNA has been identified by UCL scientists.

June Cold Spring Harbor Protocols features electrophoresis in RNA analysis and avian embryos

Gel electrophoresis is one of the most important and frequently used techniques in RNA analysis. Electrophoresis is used for RNA detection, quantification, purification by size and quality assessment. Gels are involved in a wide variety of methods including northern blotting, primer extension, footprinting and analyzing processing reactions. The two most common types of gels are polyacrylamide and agarose.

Study sheds light on molecular mechanisms of genital and urinary tract abnormalities

Scientists have learned how a gene widely known for precisely positioning and sculpting various organs also controls the speed of cell division, a finding that could be useful for understanding the explosive growth of cancer cells or why increasing numbers of children are being born with genital and urinary tract malformations.

Novel pipette technique for study of structural properties of tissues

A collaboration of French and Canadian researchers have found that sucking a portion of a spherical globule of cells into a tiny pipette provides information about the adhesion between cells and the elastic properties of the tissue. The method is a novel approach for the study of the structural properties of tissues, and should offer insights into processes such as embryonic development, tissue growth and cancer. A paper describing the research appears online in Physical Review Letters on May 24.

UNC-developed technique has broad applications in cancer, biomedical research

A precise understanding of cellular growth and movement is the key to developing new treatments for cancer and other disorders caused by dysfunctional cell behavior. Recent breakthroughs in genetic medicine have uncovered how genes control whether cellular proteins are turned 'on' or 'off' at the molecular level, but much remains to be understood about how protein signaling influences cell behavior.

RYGB surgery increases insulin activity in diabetes mellitus patients

Diabetes mellitus is a chronic metabolic disease resulted from, either decreased production of insulin or increased resistance to it from peripheral tissues or both factors combined together. While medical treatment remains the mainstay of treatment for diabetes, some surgical procedures, such as Roux-en-Y gastric bypass, have demonstrated some potential to be a treatment option for diabetes.

Research sheds light on prenatal heart formation, chromosome 22q.11 deletion syndrome

Researchers studying the common genetic disorder chromosome 22q.11 deletion syndrome have identified key proteins that act together to regulate early embryonic development. One protein is essential to life; in animal studies, embryos without the protein do not survive past the first few days of gestation.

Small piece of RNA plays big role in development of IPF: Researchers

A small piece of RNA appears to play a big role in the development of idiopathic pulmonary fibrosis (IPF), according to lung disease researchers at the University of Pittsburgh School of Medicine. Their study, which is the first to examine microRNAs in the disease, is available online in the American Journal of Respiratory and Critical Care Medicine.

Potential mate's signal activates molecular switch

A mystery about the mechanism behind sexual mate selection has been resolved. According to a new study published in the journal Nature, Universit- de Montr-al researchers have discovered a molecular switch that becomes activated in response to a potential mate's signal. Simply put, an organism knows that a potential mate is close-by and healthy enough to mate.

New insights into yeast cells may help identify cancer cells and stem cells development: Study

Yeast cells decide whether to have sex with each other within two minutes of meeting, according to new research published today in Nature. One of the authors of the study, from Imperial College London, says the new insights into how yeast cells decide to mate could be helpful for researchers looking at how cancer cells and stem cells develop.
