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.

Discovery sheds new light on the chain of events in early embryonic development

A new discovery by researchers challenges our current understanding of gastrulation, the most important stage of early embryonic development.

Study provides insights into human 8-cell-like cells and early embryonic development

The onset of embryo-specific gene transcription, also known as embryonic genome activation (EGA), is a crucial step in the developmental journey of an organism.

Scientists identify key proteins that regulate organ laterality

In order to keep track of their environment, cells use cilia, antenna-like structures that can sense a variety of stimuli, including the flow of fluids outside the cell.

Rasip1 gene found to be intimately involved in the creation of blood cells

Blood has long been a symbol of life and health, so it may be surprising that some aspects of blood production, i.e., hematopoiesis, remain incompletely understood.

Discovery could lead to more effective treatments for cancers

Case Western Reserve University biochemical researchers have identified a new function of a key protein that leads to cancer–a finding they believe could lead to more effective treatments for a range of cancers and other diseases.

Ciliopathies: A new understanding of the role of the NSL complex

The non-specific lethal (NSL) complex is a chromatin-associated factor that has been shown to regulate the expression of thousands of genes in both fruit flies and mammals.

Researchers discover new therapeutic approach for neuroblastoma

Neuroblastomas are tumors of the nervous system. They can form in many places in the body and are the most common cause of cancer-related deaths in young children.

Study finds way to reverse gene silencing in inner ear cells

A deafened adult cannot recover the ability to hear, because the sensory hearing cells of the inner ear don't regenerate after damage.

How conversion between different types of cell death contributes to disease

Researchers elucidate the role of cell death in the pathogenesis of different diseases.

The effects of oxidative stress on women’s fertility

Scientists review existing literature to assess the relationship between oxidative stress and female infertility.

Sperm packaging proteins may hold key to male infertility

Sperm play a critical role in the creation of new life, delivering essentially half of the genetic material required.

Two new compounds can block cancer cell’s escape route

Cancer cells are capable of escaping chemotherapy and radiotherapy by activating a signaling pathway that prevents them from dying.

Researchers create "synthetic embryos" from bovine pluripotent stem cells

An article published in the journal Cell Stem Cell describes the first scientific study to develop blastoids – "synthetic embryos", as they were initially (and incorrectly) called – from bovine pluripotent stem cells (PSCs).

Epigenetic formatting of satiety gene may increase risk of obesity in women

What determines whether we become overweight? Aside from lifestyle, predisposition plays a role, but genes cannot fully explain the inherited propensity to accumulate excess weight.

Study reveals molecular mechanisms of H. pylori-induced gastric carcinogenesis

Helicobacter pylori (H. pylori) infections are commonly associated with abdominal pain, bloating, and acidity. Clinical evidence suggests that infection with H. pylori cagA+ strains dramatically increases the risk of developing gastric cancer.

Scientists identify signal essential for blood-brain barrier formation

What makes the vital layer of protective cells around the brain and spinal cord -; the blood-brain barrier -; more or less permeable has been one of the more mystifying questions in neuroscience.

Season and sunshine hours may affect live birth rates after IVF

The time of year when eggs are collected from women's ovaries during fertility treatment makes a difference to live birth rates, according to new research published today (Thursday) in Human Reproduction, one of the world's leading reproductive medicine journals.
