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.

Mechanical engineer receives NIH grant to study various aspects of cell group behavior

Researchers have thought that cancer begins when a single cell goes rogue in the body, then begins to grow and multiply.

Researchers discover new cell shape that allows tissues to curve

Researchers have discovered a new cell shape called a Scutoid that allows epithelial cells to curve into tissues and form complex organ shapes.

Small RNA in sperm shown to be essential for embryonic development

New research has shown that small RNA in sperm is essential for embryo implantation and embryonic development. The findings will be used to optimize IVF.

Fluorescent zebrafish genes provide clues about neuroblastoma

Researchers have created transgenic zebrafish that could help them understand how neuroblastoma, a common pediatric cancer, develops.

Fluorescent fish could help find origins of neuroblastoma

A new type of zebrafish that produces fluorescent tags in migratory embryonic nerve precursor cells could help a Rice University neurobiologist and cancer researcher find the origins of the third-most common pediatric cancer in the U.S.

Mice study shows promise for treating genetic conditions during fetal development

Researchers at Carnegie Mellon University and Yale University have for the first time used a gene editing technique to successfully cure a genetic condition in a mouse model.

Ludwig-developed antibody drug for deadly brain cancer may have broader applications

A Ludwig Cancer Research study explains why a particular mutation in the epidermal growth factor receptor, a cell surface protein, results in more aggressive tumors and poorer overall survival of patients diagnosed with the brain cancer glioblastoma multiforme.

Researchers unmask functioning of protein involved in DNA repair during spermatogenesis

Researchers from the Department of Cell Biology, Physiology and Immunology and the Institute for Biotechnology and Biomedicine of the Universitat Autònoma de Barcelona have unmasked the functioning of a protein involved in DNA repair, ATR, in the meiotic recombination process which takes place during the development of spermatocytes - sperm precursor cells- and how inhibiting this protein causes anomalies which block spermatogenesis.

Lamin proteins organize a cell's genetic material from the sidelines

A tremendous amount of genetic material must be packed into the nucleus of every cell--a tiny compartment.

A small molecule can inhibit chemotherapy resistance of certain tumors

A team of researchers from the CNRS and Université Nice Sophia Antipolis has just shown that a small molecule called methiothepin can inhibit the chemotherapy resistance of certain tumors.

Jumping genes or transposons and their role in the genetic code

Researchers have found that there a numerous transposons or “jumping genes” within the genetic code that is responsible for development of the embryo and its growth. These were earlier thought to be junk or useless parts of the genome.

Scientists discover the molecular trigger of necroptosis

Researchers have uncovered a trigger for an immune-related cell death pathway called necroptosis. The discovery could be used to develop new treatments for cancer and immune disorders.

Study: Effects of in vitro fertilization depend on genetic variation inherited from parents

In vitro fertilization affects the regulatory region of genes essential for placental and embryonic growth, as well as the birth weight.

Researchers discover protein responsible for X chromosome inactivation

Researchers have discovered that the structural protein SMCHD1 is required to prevent genes from both X chromosomes being expressed in female mammals.

Researchers establish versatile, powerful model to analyze human cancer

Fuyuhiko Tamanoi of Kyoto University's Institute for Integrated Cell-Material Sciences and colleagues in the US succeeded in establishing a versatile, powerful and convenient model to analyze human cancer.

Study provides blueprint of how fruit flies can be used to screen potentially pathogenic human genes

It all began with one young patient; a 7-year old boy who was born without a thymus, an important organ of the immune system, and without functional immune cells. The boy also presented with cardiac and skeletal defects, dysmorphic craniofacial features and some signs of autistic behaviors.

Mapping the Genes Responsible for Pluripotency

Dr. Atilgan Yilmaz and his team have developed a method by which they can produce haploid human embryonic stem cells from oocytes. They combined this technique with CRISPR-Cas9 to generate an atlas of the genome, containing the functions of over 18,000 genes.

New study unravels secrets of HIV's persistence

Thanks to advances in the development of anti-retroviral therapy (ART), patients with HIV are living longer than ever before. And yet, even in patients on very effective, long-term ART, HIV persists, requiring patients to take antiviral medication life-long.

Researchers identify mechanisms that regulate mammary gland development

Publication in Nature Cell Biology: researchers at the Université libre de Bruxelles, ULB define for the first time the mechanisms responsible for the mammary gland development.

Study uncovers mechanism underlying brain malformation linked to severe epilepsy

One of the most frequent causes of drug-resistant epilepsy, considered a difficult disease to control, is a brain malformation known as focal cortical dysplasia.
