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.

Scientists develop 3D filming technique that reveals spread of malaria

Scientists have developed a 3D filming technique that could help inform research to stem the spread of malaria.

Rice University research reveals 3-way genetic switch for cancer metastasis

Cancer researchers from Rice University have deciphered the operating principles of a genetic switch that cancer cells use to decide when to metastasize and invade other parts of the body. The study found that the on-off switch's dynamics also allows a third choice that lies somewhere between "on" and "off." The extra setting both explains previously confusing experimental results and opens the door to new avenues of cancer treatment.

Activation mechanism of protective protein in ocular lens resolved

The lens of the human eye is made up of a highly concentrated protein solution that imparts the eye its high refractive power. Yet, despite this high protein content the ocular lens must remain clear and transparent.

Research: Hypermutation in cancer is more frequent in inactive X chromosome

Every case of cancer originates from changes in a person's genetic material (mutations). These usually occur as "somatic mutations" in individual cells during an individual's lifetime, rather than being inherited from a person's parents.

Seven promising scientists named 2013 NYSCF - Robertson Investigators

The New York Stem Cell Foundation today named seven of the most promising scientists as its 2013 NYSCF - Robertson Investigators.

IRCM researchers identify new proteins crucial for hearing

A team of researchers led by Dr. Michel Cayouette at the IRCM made an important discovery, published online yesterday by the scientific journal Developmental Cell, that could better explain some inherited forms of hearing loss in humans. The Montr-al scientists identified a group of proteins crucial for shaping the cellular organ responsible for detecting sounds.

Scientists develop new method to create stem cells for human liver and pancreas

A new method for creating stem cells for the human liver and pancreas, which could enable both cell types to be grown in sufficient quantities for clinical use, has been developed by scientists.

Genetic mutation that protects skin from UV radiation may cause testicular cancer in Caucasian

A Ludwig Cancer Research study published in Cell today identifies a common mutation that dramatically increases the risk for testicular cancer—and describes a likely molecular mechanism by which it exerts that effect.

Study identifies new potential genetic culprits in origins of congenital heart defects

Mitochondria are the power plants of cells, manufacturing chemical fuel so a cell can perform its many tasks. These cellular power plants also are well known for their role in ridding the body of old or damaged cells.

Sister stem cells display considerable differences despite having identical DNA

Scientists have used a brand new technique for examining individual stem cells to uncover dramatic differences in the gene expression levels - which genes are turned 'up' or 'down'- between apparently identical 'sister' pairs.

Scientists develop model to study the behavior of embryonic tissue

A team of scientists, including M. Lisa Manning, assistant professor of physics in Syracuse University's College of Arts and Sciences, has developed a model for studying tissue-specifically how it organizes into organs and layers during embryonic development.

Research offers new perspectives on cortical structure's development

The cerebral cortex is the most complex and vital structure in our brain. It is the nerve centre for those "higher" functions that characterise our species, such as language and abstract thought. The nerve cells - or neurons - which comprise the cortex are key elements in ensuring its functions effectively.

Wnt proteins essential to formation of long-term memories

Scientists from the Florida campus of The Scripps Research Institute have found a group of proteins essential to the formation of long-term memories.

Research uncovers defective process in patients with autosomal dominant polycystic kidney disease

New research has uncovered a process that is defective in patients with autosomal dominant polycystic kidney disease, a common cause of kidney failure. The findings, which appear in an upcoming issue of the Journal of the American Society of Nephrology (JASN), point to a new potential strategy for preventing and treating the disease.

Study shows metastasizing cancer cells undergo molecular change during EMT

For the majority of cancer patients, it's not the primary tumor that is deadly, but the spread or "metastasis" of cancer cells from the primary tumor to secondary locations throughout the body that is the problem. That's why a major focus of contemporary cancer research is how to stop or fight metastasis.

Pregnant women with thyroid hormone deficiency are 4 times likelier to produce autistic children

Pregnant women who don't make nearly enough thyroid hormone are nearly 4 times likelier to produce autistic children than healthy women, report scientists from the Houston Methodist Neurological Institute and Erasmus Medical Centre in an upcoming Annals of Neurology (online today).

High mobility group (HMG) genes and cancer: an interview with Dr. Linda Resar, Johns Hopkins University School of Medicine

High mobility group A genes are highly expressed in all aggressive cancers studied to date. These genes encode the high mobility group A (HMGA) proteins. In other words, these genes provide the genetic “code” necessary to produce HMGA proteins.

Understanding the movement of neurons sheds light on how cancer cells invade health tissues

The invasion of brain-tumor cells into surrounding tissue requires the same protein molecule that neurons need to migrate into position as they differentiate and mature, according to new research from the University of Illinois at Chicago College of Medicine and published August 7 in the online journal PLOS ONE.

Study: Stem cells in mouth tissue can relieve inflammatory disease

Stem cells found in mouth tissue can not only become other types of cells but can also relieve inflammatory disease, according to a new Ostrow School of Dentistry of USC study in the Journal of Dental Research.
