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.

Online health technology can close the gap on racial disparities

New research from Boston Medical Center highlights the benefits of using health technology to engage African American and Black women earlier in preconception care in an effort to close the gap on racial disparities in birth outcomes and maternal mortality.

Scientists create miniature human heart model in the lab

A team of researchers from Michigan State University has created a miniature human heart model in the laboratory. For the first time in history, this mode is complete with all primary heart cell types and a functioning structure of chambers and vascular tissue.

Genes on the X chromosome may be key to melanoma survival advantage in females

Centenary Institute scientists have discovered that genes on the X chromosome may be key to the improved survival rates of females with melanoma–as compared to their male counterparts.

Miscarriage risk increases with each additional week of alcohol exposure in early pregnancy

Each week a woman consumes alcohol during the first five to 10 weeks of pregnancy is associated with an incremental 8% increase in risk of miscarriage, according to a study by Vanderbilt University Medical Center researchers.

Study reveals the genetic cause of congenital malformation

Study by the University of Bonn reveals that genetic information controls development of the urinary tract, rectum and genitals Spontaneous mutations of a single gene are likely to cause serious developmental disorders of the excretory organs and genitalia.

4D OCT can provide unprecedented information about 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.

Study shows how regulatory mechanisms contribute to formation of tissues in mouse embryo

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"

Continuous survival of neurons is intrinsically programmed during development

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. Researchers have generally believed that their survival is determined nearly extrinsically, or by outside forces, such as the tissues and cells that neurons supply with nerve cells.

Researchers use optogenetics to activate and inactivate signaling pathways

Proper embryonic development of the fruit fly Drosophila melanogaster is governed by patterns of protein activity bequeathed to the fertilized egg by its mother.

New model may explain why certain cancer cells are resistant to therapy

Cancer's knack for developing resistance to chemotherapy has long been a major obstacle to achieving lasting remissions or cures.

White blood cells and their role in the brain

Researchers have found that the brain has specific immune cells that help in normal brain development and play a role in certain neurological diseases.

Study points to an important role for white blood cells in brain development

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

New method uses human embryonic stem cells to generate 3D assembly of cells

Scientists from the University of Cambridge, in collaboration with the Hubrecht Institute in The Netherlands, have developed a new model to study an early stage of human development, using human embryonic stem cells.

Study provides molecular explanation to a longstanding mystery in viral oncology

The oncogenic herpesvirus (HHV8 or KSHV) causes a cancer known as Kaposi's Sarcoma. An international team of scientists led by the University of Helsinki has discovered key factors that control the genome maintenance and replication of a virus responsible for lymphatic vascular cancer.
