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.

Study decodes genetic program responsible for development of mammalian cerebellum

The cerebellum has been linked almost exclusively with motor control; however, research shows that it also contributes to numerous higher brain functions.

New test to detect substances that are harmful to the placenta and embryo

Researchers at ETH Zurich have developed a cell culture test to detect substances that are directly or indirectly harmful to embryos. Based on an existing test used for developing new drugs and chemicals, the augmented version is designed to help reduce the number of animal experiments.

Scientists are paving the way for cancer treatments with fewer side effects

In recent years, immunotherapy has revolutionized the field of cancer treatment. However, inflammatory reactions in healthy tissues frequently trigger side effects that can be serious and lead to the permanent discontinuation of treatment.

New microscope helps observe the whole body of the embryo

A research group led by Takashi Saito, of the Ehime University Graduate School of Medicine, developed a 2-photon excitation light-sheet fluorescence microscope which (1) lowers phototoxicity, (2) extends the field of view, and (3) heightens spatial resolution.

Study reveals molecular mechanisms involved in the maintenance of naïve embryonic stem cells

Researchers have explained mechanisms that play a role in maintaining the embryonic stem cells in the most optimized state for use in regenerative medicine.

Study reveals mechanism that regulates genes on sex chromosomes

In the human population, males have one X and one Y chromosomes and females have two X chromosomes. As a result, somatic cells have unique mechanisms that maintain the same gene expression levels on the X chromosome between both genders.

New statistical study shows how pairs of cancer cells interact

One of the fundamental principles of biology is the fact that cells are motile and make contact with one another.

Pioneer transcription factors help turn on key genes that give cells unique properties

Biologists have long wondered how complex organisms contain a variety of dramatically different types of cells with specialized functions, even though all of those cells are genetically identical.

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.
