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 test effects of weedkiller on wildlife

Prolonged exposure to environmentally relevant concentrations of the weedkiller Roundup causes significant harm to keystone species according to new research at the University of Birmingham.

Researchers provide a list of genes implicated in congenital heart disease

Over two million babies, children, and adults in the United States are living with congenital heart disease--a range of birth defects affecting the heart's structure or function.

Research reveals fundamental insights into the causes of severe birth defects

Research by Kai Jiao, M.D., Ph.D., and colleagues at the University of Alabama at Birmingham and in Germany has yielded fundamental insights into the causes of severe birth defects known as CHARGE syndrome cases. These congenital birth defects include severe and life-threatening heart malformations.

Researchers identify molecular mechanisms that reverse aging

Cellular reprogramming can reverse the aging that leads to a decline in the activities and functions of mesenchymal stem/stromal cells (MSCs).

Study outlines transient prospective stages in development of neural crest cells

Last year, researchers at the University of California, Riverside, identified the early origins of neural crest cells -- embryonic cells in vertebrates that travel throughout the body and generate many cell types -- in chick embryos.

Study reveals how the loss of a protein affects proper brain development

Normal brain development requires a precise interplay between neuronal and non-neuronal (also called glial) cells. In a new study, researchers from the University of Tsukuba revealed how the loss of protein arginine methyltransferase (PRMT) 1 causes disruptions in glial cells and affects proper brain development.

Research finds gene family critical to unlocking vertebrate evolution

New University of Colorado Boulder-led research finds that the traits that make vertebrates distinct from invertebrates were made possible by the emergence of a new set of genes 500 million years ago, documenting an important episode in evolution where new genes played a significant role in the evolution of novel traits in vertebrates.

How do Neural Stem Cells become Nerve Cells?

Professor Vanderhaeghen speaks to AZoLifeSciences about his teams research discovery on mitochondria, and their involvement during brain development.

4D optical coherence tomography offers insight into embryonic heart development

How a valveless embryonic heart tube pumps blood is a long-standing scientific mystery. Thanks to innovations in light-based technology, fresh insights are now available into the biomechanics of mammalian cardiogenesis-;and in particular, the pumping dynamics of the mammalian tubular embryonic heart.

Scientists explore the role of epigenetic regulator factors in embryonic development

A research team at the Max Planck Institute for Molecular Genetics in Berlin has explored the role of factors in embryonic development that do not alter the sequence of DNA, but only epigenetically modify its "packaging".

'Marie Kondo' enzyme helps fruit fly embryos to clean out maternal proteins

Researchers at the University of Colorado School of Medicine have discovered a protein in fruit fly embryos, dubbed Marie Kondo, that destroys maternal proteins.

Researchers identify mechanism that prevents death of neurons

When our neurons -- the principle cells of the brain -- die, so do we. Most neurons are created during embryonic development and have no "backup" after birth.

Study shows how cancer develops resistance to chemotherapy

Cancer's knack for developing resistance to chemotherapy has long been a major obstacle to achieving lasting remissions or cures. While tumors may shrink soon after chemotherapy, many times they eventually grow back.

Study sheds light on the role of white blood cells in the developing brain

Whether white blood cells can be found in the brain has been controversial, and what they might be doing used to be complete mystery.

Novel technology significantly improves the quality of stem cells

For years, stem cells have continued to have excellent potential in regenerative medicine.

Researchers create a new model to study early stage of human development

Researchers from the University of Cambridge have devised a new model to analyze an early stage of human development through human embryonic stem cells.

Lab-grown organoids can prevent hair loss

Researchers have created a new, hair-germinating piece of human skin in the laboratory that might prevent hair loss in the days to come.

Study reveals forces that control tissue flow in Drosophila embryo

During the development of embryos, tissues flow and reorganize significantly on timescales within minutes.

New model mimics early embryonic stages of the human brain

We know a lot about the human brain, but very little about how it is formed. In particular, the stages from the second to the seventh week of embryonic development have so far been virtually unknown territory to brain researchers.

Mouse model helps track organism’s development, cell by cell

Scientists at the Stem Cell Research program at Boston Children's Hospital and Dana-Farber Cancer Institute/Harvard Medical School have devised a mouse model that lets researchers track every cell in the body, from the embryonic stage until adulthood.
