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.
Cornell researchers have taken a major step toward answering a key question in cancer research: Why is testicular cancer so responsive to chemotherapy, even after it metastasizes?
Researchers at the University of California San Diego School of Medicine, with colleagues in Brazil, report that the Zika virus is transmitted from mother to fetus by infected cells that, ironically, will later develop into the brain's first and primary form of defense against invasive pathogens.
Pediatric high-grade glioma is the primary cause of cancer death in children. Genesis of these tumors is believed to be driven by mutations in proteins that disrupt fundamental mechanisms governing the development of the human brain.
Cancer cells can reactivate a cellular process that is an essential part of embryonic development. This allows them to leave the primary tumor, penetrate the surrounding tissue and form metastases in peripheral organs.
Environmental health scientist Alicia Timme-Laragy at the University of Massachusetts Amherst recently received a $1.9 million grant from the National Institute of Environmental Health Sciences to study the health effects of two environmental pollutants, perfluoro-octanesulfonic acid (PFOS) and its recent replacement chemical, perfluoro-butanesulfonic (PFBS).
Recent research discoveries in the development of brain disorders could pave the way to new therapies for treating seizures, and even some children with autism, says a leading oncologist and researcher at the University of Alberta.
In discovering how certain chemotherapy drugs cause the nerve damage known as peripheral neuropathy, researchers at Dana-Farber Cancer Institute have found a potential approach to preventing this common and troublesome side effect of cancer treatment.
Scientists at Albert Einstein College of Medicine have discovered the first compound that directly makes cancer cells commit suicide while sparing healthy cells.
Removal of a regulatory gene called LSD1 in adult mice induces changes in gene activity that that look unexpectedly like Alzheimer's disease, scientists have discovered.
Researchers at the University of Helsinki, Finland, have found a genetic variation, which associates with the damage caused by maternal alcohol consumption. This genetic variation clarifies the role of genetic factors in the alcohol-induced developmental disorders and could be useful in future diagnostics.
A newly discovered cellular messaging mechanism could lead to a new way to deliver therapeutics to tissues affected by disease, according to a new study from Harvard T.H. Chan School of Public Health.
A sophisticated system of 'social control' operating between neighboring cells allows embryos to protect the purity of their pluripotent cell population, which is able to generate all body tissues.
Researchers have used a genome-editing technique to elucidate the role of a gene that is key to human embryonic development.
A recent study led by Samantha Butler at the Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research at UCLA has overturned a common belief about how a certain class of proteins in the spinal cord regulate the formation of nervous system cells -- called neurons -- during embryonic development.
New insights into the development of the vascular system: researchers in the team of Dr Carmen Ruiz de Almodóvar of the Heidelberg University Biochemistry Center have discovered a crucial biological step that regulates the formation of blood vessels.
Mesothelioma is a rare and aggressive tumor that, in many cases, results from exposure to asbestos. But over the last several decades, other causes of the disease have emerged, including treatment with high-intensity therapeutic radiation and, more recently, an inherited genetic mutation.
NYIT has been awarded $442,000 to pursue research into a gene critical in the formation and healing of bones.
Retrotransposons are repetitive elements that form almost half of the mammalian genome. Even though they are so common, they have previously been considered to be fairly insignificant.
In the evolution of tetrapods, the position of the hindlimb has diversified along with the vertebral formula, which is the number of small bones forming the vertebra. Tetrapods, as the name implies, are species that have four feet.
Scientists reveal that a fault in the process that copies DNA during cell division can cause epigenetic changes that may be inherited for up-to five generations.
