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.

Researchers identify key gene network responsible for severe tooth enamel defects

Mutations in a certain molecule result in severe damage in the structure and mineral composition of tooth enamel in mice, according to a study conducted at the UZH Center of Dental Medicine.

Medulloblastomas originate much earlier in pregnancy than previously thought and may be preventable

An aggressive type of pediatric brain tumor, medulloblastoma, exists in a pre-malignant form at birth after initially developing during the first or second trimester of pregnancy, according to a new international study.

New genetic discovery improves understanding of congenital heart disease

A new study led by the Masonic Medical Research Institute published in the journal Cells shows for the first time that a particular gene, called VGLL4, is required for embryo development but is dispensable for myocardial growth.

Research reveals the role of microglia-neuron connections during brain development

The Laboratory of Neuroimmunology of the Institute of Experimental Medicine, Budapest, Hungary, led by Ádám Dénes, describes the presence of a direct interaction site between microglial cells and the cell body of developing neurons, and reveals its role during brain development.

Discoveries about embryonic blood stem cell creation may solve donor blood stem cell shortages

Making stem cells from a patient’s adult cells – rather than human embryos – is one of the holy grails in modern medicine treatments. New research brings us two steps closer.

Low-dose ketamine is safe and effective to treat children with ADNP syndrome, study suggests

Results of a small, but unique research study, led by researchers from the Seaver Autism Center for Research and Treatment at Mount Sinai and published online in Human Genetics and Genomic Advances, suggest that low-dose ketamine is generally safe, well-tolerated and effective to treat clinical symptoms in children diagnosed with ADNP syndrome (also known as Helsmoortel-VanDerAa syndrome), a rare neurodevelopmental disorder caused by mutations in the activity dependent neuroprotective protein (ADNP) gene.

Research shows how orderly regeneration is activated after injury

The phenomenon of regeneration was discovered over 200 years ago in the freshwater polyp Hydra. Until now, however, it was largely unclear how the orderly regeneration of lost tissues or organs is activated after injury.

Researchers demonstrate improved culture of primate induced pluripotent stem cells

The following study transplanted iPSCs derived from two NHP species, chimpanzee and pigtailed macaque, into blastocysts from another NHP species – the rhesus macaque.

Gothenburg scientists discover possible new cancer treatment target

Researchers at the University of Gothenburg have identified a previously unknown mechanism controlling tumor growth in cultured cells and mice.

Mouse embryoids offer a promising model system to spur research into embryonic development and disease

Scientists funded in part by the National Institutes of Health have generated a mouse embryo model, or embryoid, that develops beyond neurulation—formation of the neural tube, which gives rise to the central nervous system—and closely mirrors natural mouse embryos 8.5 days after fertilization.

Scientists discover a mechanism used by insects in the development and regeneration of wings

The first mutation of the wingless gene was found by accident in Drosophila in the 1970s, following the observation of flies that did not possess wings, hence its name.

New resource can help researchers to assess how key genes control the differentiation of developing embryos

Years of work by developmental biologists from Trinity College Dublin, working with colleagues at the University of Edinburgh's MRC Human Genetics Unit, has yielded a resource of unparalleled detail that will help researchers assess how key genes control the differentiation of tissues and organs of developing embryos.

Circuits of touch and sight are intermingled in the embryo, study shows

In embryonic stages, tactile stimuli simultaneously activate tactile and visual neural pathways. Shortly after birth, both pathways reorganize to allow separate processing of touch and vision.

Scientists unravel the development of main immune cell population residing in the brain

New research published today by the University of Southampton shows new insight in how our brain develops, that can pave the way for treating neurological disorders.

UT Southwestern's cryo-EM images shed light on the mechanisms behind Wnt signaling activation

Using UT Southwestern's Cryo-Electron Microscopy Facility, researchers have captured images of an enzyme for Wnt lipidation, which is pivotal to human development and cancer and crucial for Wnt signaling activation.

UMass Amherst scientist to study how embryonic exposure to pollutants may increase diabetes risk

A University of Massachusetts Amherst environmental health scientist has received a $2.44 million, five-year grant renewal from the National Institutes of Health to continue her research into how embryonic exposure to certain common pollutants may put people at risk for diabetes and other metabolic health conditions later in life.

IMBA researchers uncover basic principles of early development using blastoids

One often thinks that the early embryo is fragile and needs support. However, at the earliest stages of development, it has the power to feed the future placenta and instructs the uterus so that it can nest.

New research helps to better understand the basic biology of nerve cells

Scientists are starting to understand the precise workings of a type of gene that, unlike other genes, does not code for proteins – the building blocks of life.

AKT inhibitor miransertib could be a promising new treatment against low-flow vascular malformations

A team of researchers led by Dr. Sandra Castillo and Dr. Mariona Graupera, from the Josep Carreras Leukaemia Research Institute and member of the CIBERONC, have found the AKT inhibitor miransertib could be a new molecular treatment effective against low-flow vascular malformations, a long-awaited milestone.

New protocol can develop safe, efficient pluripotent stem cell-based therapies for macular degeneration

As we age, so do our eyes; most commonly, this involves changes to our vision and new glasses, but there are more severe forms of age-related eye problems.
