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.

New molecular mechanism involved in pancreas repair identified

Ramón Muñoz-Chápuli and Rita Carmona, researchers of the UMA Department of Animal Biology, have identified a new molecular mechanism involved in pancreas repair.

Natural speed limit on DNA replication sets pace for life's first steps

Fruit flies make for stingy mothers, imparting only a portion of the genetic building blocks their offspring need to survive. The rest must be produced by the fertilized egg in its first few steps of growth.

Nicotine could affect human embryonic development at the single-cell level

Nicotine induces widespread adverse effects on human embryonic development at the level of individual cells, researchers report February 28th in the journal Stem Cell Reports.

Protein signaling in embryos is far more complex than previously thought

How cells in developing embryos communicate depends a great deal on context, according to scientists at Rice University.

Researchers discover new mechanism of bone growth

In a paper published in the journal Nature, an international research team led by researchers at Karolinska Institutet in Sweden report that bone growth in mice takes place in accordance with the same principles as when new cells are constantly produced in blood, skin and other tissue.

Study gives a snapshot of crocodile evolution

The story that's often told about crocodiles is that they're among the most perfectly adapted creatures on the planet - living fossils that have remained virtually unchanged for millions of years.

Researchers create new map of the brain's own immune system

A team of researchers under the direction of the Medical Center - University of Freiburg has created an entirely new map of the brain's own immune system in humans and mice.

Mutations in folliculin gene affect embryo implantation

New information is unfolding on the genetic controls of an early turning point in pregnancy. As the tiny, dividing cell mass, the blastocyst, travels from the oviduct and lodges in the wall of the uterus, the cells must exit their pre-implantation state and be ready for post-implantation development.

Study reveals mechanisms responsible for embryonic development in fruit flies

The first moments of life unfold with incredible precision. Now, using mathematical tools and the help of fruit flies, researchers at Princeton have uncovered new findings about the mechanisms behind this precision.

Study sheds light on the genetic causes of tumors in salivary glands

Acinic cell carcinoma is the third most common malignant form of salivary gland cancer. These tumors are similar to normal salivary gland tissue and occur most frequently in the parotid gland.

Behavioral experiments confirm that additional neurons improve brain function

Most neurons in the human brain are generated from neural stem cells during embryonic development. After birth, a small reservoir of stem cells remains in the brain that keeps on producing new neurons throughout life.

Breast cancer cells in mice coaxed to turn into harmless fat cells

As cancer cells respond to cues in their microenvironment, they can enter a highly plastic state in which they are susceptible to transdifferentiation into a different type of cell.

Turning breast cancer cells into fat cells prevents the formation of metastases

An innovative combination therapy can force malignant breast cancer cells to turn into fat cells. This can be used to prevent the formation of metastases in mice, as researchers at the University of Basel's Department of Biomedicine recently reported in the journal Cancer Cell.

A small protein plays key role in how cancer stem cells differentiate

A jagged little protein appears to be key to how cancer stem cells differentiate and enable metastasis, according to researchers at Rice University and the Duke University School of Medicine.

Researchers discover new mechanism behind spread of malignant pleural mesothelioma

Malignant pleural mesothelioma is divided into three subtypes, one of which is particularly aggressive. Researchers from the Comprehensive Cancer Center of MedUni Vienna and Vienna General Hospital have now managed to discover a mechanism that contributes to this aggressive behavior: the tumor cells of this subtype are able to assume special characteristics that promote migration and therefore spread of the cancer.

Disrupted biological clock can contribute to onset of diseases, USC study shows

USC scientists report that a novel time-keeping mechanism within liver cells that helps sustain key organ tasks can contribute to diseases when its natural rhythm is disrupted.

New computational model provides clearer picture of shape-changing cells' structure and mechanics

A new computational model developed by researchers from The City College of New York and Yale gives a clearer picture of the structure and mechanics of soft, shape-changing cells that could provide a better understanding of cancerous tumor growth, wound healing, and embryonic development.

New EU-funded project provides insight into how the brain develops

The human brain is comprised of billions of different types of cells. These cells are then organized into sophisticated networks, each of which determines a specific function of the brain. But how do the neurons, or nerve cells that form these networks, find the right network? And what happens when they don’t?

Researchers succeed in converting human skin cells into blood stem cells

Researchers have succeeded in converting human skin cells into blood stem cells in an international collaboration project.

International study of ADHD at genomic scale

An international study, focused on the analysis of the genome of more than 50,000 people worldwide, has identified twelve specific fragments of DNA related to the vulnerability of the attention deficit hyperactivity disorder.
