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.

Mechanism that controls embryonic development could also prevent cancer

Researchers from Mount Sinai School of Medicine have identified a mechanism controlling the function of a protein that binds to DNA during embryonic development and may function to prevent abnormal tumor growth.

Mirna announces USPTO allows claims to therapeutic application of let-7 miRNA

Mirna Therapeutics, Inc. announced today that the USPTO has allowed claims related to the therapeutic application of let-7 in the regulation of oncogenes. The claims derive from a patent application that was submitted by Yale University and exclusively licensed to Mirna related to the pioneering work of Dr. Frank Slack, Professor of Molecular, Cellular & Developmental Biology at Yale University in New Haven, CT.

Scientists discover 'switch' mechanism of lymphatic and blood vessel cells

Scientists at the University of East Anglia have made an important breakthrough in the way anti-cancer drugs are tested. A tumour cannot grow to a large size or spread until it has developed its own blood supply and leading research has looked for a way of halting capillary formation to stop tumours taking hold.But new findings published today in the Journal of Cell Science have shown that scientists testing such treatments may not have been studying exactly what they thought they were.

Genentech initiates GDC-0449 Phase II clinical trial in BCC patients

Curis, Inc. a drug development company seeking to develop next generation targeted small molecule drug candidates for cancer treatment, today announced that its collaborator Genentech, a member of the Roche Group, has initiated a Phase II clinical trial of GDC-0449, an orally-administered small molecule Hedgehog Pathway Inhibitor, as a single-agent therapy for patients with operable basal cell carcinoma (BCC).

PDGF identified as key factor in proliferation and transformation of epicardial cells

In research that one day may lead to the discovery of how to regenerate tissue damaged by heart disease, investigators at Childrens Hospital Los Angeles have identified PDGF as a key factor in the proliferation and transformation of epicardial cells, one type of cell that surrounds heart muscle and contributes to vessels.

Researchers identify ways to predict embryonic developmental success

Two-thirds of all human embryos fail to develop successfully. Now, in a new study, researchers at the Stanford University School of Medicine have shown that they can predict with 93 percent certainty which fertilized eggs will make it to a critical developmental milestone and which will stall and die. The findings are important to the understanding of the fundamentals of human development at the earliest stages, which have largely remained a mystery despite the attention given to human embryonic stem cell research.

Women & Infants Hospital receives $2.1M NIH grant to continue work under COBRE for Perinatal Biology

Women & Infants Hospital has recently received a $2.1 million grant from the National Institutes of Health to continue work under the Center of Biomedical Research Excellence for Perinatal Biology. Of the 108 COBREs across the country, Women & Infants is the only one specifically focused on developmental research.

Six3 gene safeguards future retina

New research led by St. Jude Children's Research Hospital investigators adds to evidence that the Six3 gene functions like a doorman in the developing brain and visual system, safeguarding the future retina by keeping the region where the eye is forming free of a signaling protein capable of disrupting the process.

Study finds new therapeutic target for polycystic kidney disease

In work suggesting a new approach to treating polycystic kidney disease (PKD), a leading cause of kidney failure, researchers at Children's Hospital Boston were able to block the formation of fluid-filled cysts, the hallmark of the disease, in a mouse model. Their findings, using a compound that inhibits a receptor known as c-Met, will be published in the September 13th online edition of the Journal of Clinical Investigation.

Research on iPS cells can imply potential cell therapy for X-linked disorders

Female induced pluripotent stem (iPS) cells, reprogrammed from human skin cells into cells that have the embryonic-like potential to become any cell in the body, retain an inactive X chromosome, stem cell researchers at UCLA have found.

Researchers identify two proteins in cellular response to mechanical stimulation

Scripps Research Institute scientists have identified two proteins with potential to be important targets for research into a wide range of health problems, including pain, deafness, and cardiac and kidney dysfunction.

Breast cancer accomplice discovered

Scientists have discovered an accomplice in breast cancer - a master control switch with the power to set off a cascade of reactions orchestrated by a cancer-causing gene (or oncogene) named Wnt1. This executive molecule and its modus operandi are reported in back-to-back papers featured on the cover of the August 15 issue of Cancer Research.

RPA70 associated with SUMO-specific protease facilitates DNA repair: Research

A team of investigators led by a physician-scientist at The University of Texas MD Anderson Cancer Center has shown for the first time that the small protein SUMO can team up with the replication protein A (RPA) complex to facilitate DNA repair. The study is published in the Aug. 13 edition of the journal Molecular Cell.

Study implicates Fritz's role in human genetic disorders

Mutations in a gene known as "Fritz" may be responsible for causing human genetic disorders such as Bardet-Biedl syndrome, University of Texas at Austin developmental biologist John Wallingford and Duke University human geneticist and cell biologist Nicholas Katsanis have found.

New research identifies stem cells that generate three critical classes of nerve cells

New research, published in the journal Development, by Dr. Anthony-Samuel LaMantia, professor of Pharmacology & Physiology and director of the newly formed GW Institute for Neuroscience, and his colleagues have identified the stem cells that generate three critical classes of nerve cells - olfactory receptors, vomeronasal and gonadotropin releasing hormone neurons - that are responsible for enabling animals and humans, to eat, interact socially and reproduce.

Researchers report how mature red blood cells form

We take our blood for granted, but its creation requires a complicated series of steps, starting with the formation of blood stem cells during early embryonic development, followed by progressive differentiation into the progenitors of red cells, white cells and platelets, and ultimately the full set of blood cells.
