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 reveals new role for gene associated with autism spectrum disorder

A UCLA-led study reveals a new role for a gene that's associated with autism spectrum disorder, intellectual disability and language impairment.

Macrophages migrate from the blood to attack brain tissue shortly after stroke

Macrophages are part of the innate immune system and essential for brain development and function. Using a novel method, scientists from Jena University Hospital, the University of Bonn and the Memorial Sloan Kettering Cancer Center in New York (USA) succeeded in visualizing macrophages that were formed in the bone marrow.

Developmental shape-shifting is key to cancer's ability to spread and evade immune defenses

Just as people tend to become stuck in their ways as they grow older so too do cells. Neurons in the brain don't one day decide to become heart cells; skin cells repair wounds with skin cells rather than kidney cells.

Pioneering project on genomic edition through CRISPR/Cas9 to study early embryonic development

Characterization studies of early embryonic development are limited, mainly due to the lack of samples and the obvious legal and ethical limitations.

Study explores how some mammals postpone development of their embryos

How do some mammals postpone the development of their embryos to await better conditions for having offspring? A recent study at the UW Medicine Institute for Stem Cell and Regenerative Medicine explored this reproductive enigma, which can occur in more than 130 species of mammals as well as in some marsupials.

Naturally produced protein suppresses breast cancer metastasis

A protein naturally produced in the body has been found to suppress breast cancer metastasis in animal models of human tumors. Researchers led by Baylor College of Medicine also found that high levels of this protein, AKAP8, predicts a better survival for breast cancer patients.

Study: Benefits of fetal surgery to repair spina bifida continue through school age

The benefits of fetal surgery to repair spina bifida, a procedure pioneered at Vanderbilt University Medical Center (VUMC) in 1997, continue through school age, a National Institutes of Health (NIH) study reports today in the journal Pediatrics.

Pilot study highlights the effect of chemotherapy on male fertility

A pilot study conducted by INRS researchers highlights the effect of chemotherapy on male fertility before and after puberty.

Plastic microfibers increase mortality and decrease reproductive success in sand crabs

Sand crabs, a key species in beach ecosystems, were found to have increased adult mortality and decreased reproductive success when exposed to plastic microfibers, according to a new Portland State University study.

Study shows how cancer-causing genes promote metastasis

Cancer-promoting genes MYC and TWIST1 co-opt immune system cells to enable cancer cells to spread, but blocking a key step in this process can help prevent the disease from developing.

Study sheds new light on impact of common plasticizer on human reproductive health

Researchers at Harvard Medical School and the New York State Department of Health have discovered how a common plasticizer associated with human reproductive abnormalities likely does its damage at the molecular level.

First in vitro system can help study early spine development in humans

More than 20 years ago, the lab of developmental biologist Olivier Pourquié discovered a sort of cellular clock in chicken embryos where each "tick" stimulates the formation of a structure called a somite that ultimately becomes a vertebra.

Common plasticizer leads to fertility problems in roundworms

A new study published 9th January in PLOS Genetics by Mónica Colaiácovo of Harvard Medical School and colleagues reports that the most commonly used plasticizer, diethylhexyl phthalate, leads to fertility problems by causing an excess number of breaks in the DNA during egg production, and then interfering with the repair systems that fixes the breaks.

Scientists discover potential drug compounds that target common type of liver cancer

Scientists from the Cancer Science Institute of Singapore at the National University of Singapore, and the Agency for Science, Technology and Research (A*STAR)'s Genome Institute of Singapore have discovered four potential drug compounds that target hepatocellular carcinoma, the most common type of liver cancer.

Scientists identify molecular mechanisms that protect cells against mechanical stress

Scientists at the Centro Nacional de Investigaciones Cardiovasculares (CNIC) have identified the molecular mechanisms that allow our cells to adapt to, protect themselves against, and survive mechanical stress.

Study provides genomic insights into life history tradeoffs in butterflies

Have you ever wandered through your garden or a meadow on a summer day and wondered why and how butterflies exhibit such beautiful and diverse colors? Scientists have, especially when thinking about butterflies in the genus Colias. In most Colias butterflies, all males and most females are an orange or yellow color, but some females are white.

A new function identified for glycine receptors during embryonic development

Glycine receptors are one of the most widely distributed inhibitory receptors in the central nervous system and have important roles in a variety of physiological processes.

Penn researchers track defective sperm epigenome linked to male infertility

One out of eight couples has trouble conceiving, with nearly a quarter of those cases caused by unexplained male infertility. For the past decade, research has linked that infertility to defective sperm that fail to "evict" proteins called histones from DNA during development.

Important discovery about male infertility could lead to new treatments

Using a new mouse model, Penn Medicine researchers have identified defects in the sperm epigenome that cause male infertility.

Discovery of novel mechanism by which certain breast cancers can metastasize

Researchers from the Baylor College of Medicine and Harvard Medical School have found a novel mechanism to explain the resistance of certain breast cancers that spread in the major organs of the body. They hope that this would help develop new therapeutic strategies to treat the cancer.
