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.
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.
Scientists have, for the first time, corrected a disease-causing mutation in early stage human embryos with gene editing.
Using the gene editing technology CRISPR, scientists have shed light on a rare, sometimes fatal syndrome that causes children to gradually lose the ability to manufacture vital blood cells.
Gradients of molecular signaling factors play an essential role in numerous events in embryonic development, from patterning limb and organ formation to the intricate shaping of the brain and neuroanatomical architecture.
A new report by the National Academies of Sciences, Engineering, and Medicine proposes a strategy that the U.S. Environmental Protection Agency should use to evaluate the evidence of adverse human health effects from low doses of exposure to chemicals that can disrupt the endocrine system.
A study of nearly 6,000 families, combining three genetic sequencing technologies, finds that mutations that occur after conception play an important role in autism.
Like it or not, as we age, our muscle cells are slowly exchanged, one by one, for fat cells. This process quickens when we injure a muscle, and an extreme form of this process is also seen in muscle-wasting diseases such as Duchenne muscular dystrophy (DMD).
Pioneering research using the tropical zebrafish could provide new insights into the genetic basis of myopathy, a type of human muscle disease.
Scientists have uncovered how nerve cells in the spinal cord are organized in precise patterns during embryo development - a finding that could give insight into regenerative medicine.
Humans belong to a select club of species that enjoy crisp color vision in daylight, thanks to a small spot in the center of the retina at the back of the eye.
Scientists used human pluripotent stem cells to generate human embryonic colons in a laboratory that function much like natural human tissues when transplanted into mice, according to research published June 22 in Cell Stem Cell.
A new study at the Edward Via College of Osteopathic Medicine and the Virginia-Maryland College of Veterinary Medicine at Virginia Tech has found a connection between common household chemicals and birth defects.
The 22q11.2 region of human chromosome 22 is a hotspot for a variety of birth defects. Scientists learned about this region because it is deleted in about 1 in 4,000 births, causing the loss or duplication of up to 40 genes.
