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.

Tel Aviv University pinpoints mechanism that causes rare and severe congenital syndrome

In the 1950s and 1960s, pregnant women with morning sickness were often prescribed the new drug thalidomide. Shortly after the medicine was released on the market, a reported 10,000 infants were born with an extreme form of the rare congenital phocomelia syndrome, which caused death in 50 percent of cases and severe physical and mental disabilities in others.

Human fat: A Trojan horse to fight brain cancer?

Johns Hopkins researchers say they have successfully used stem cells derived from human body fat to deliver biological treatments directly to the brains of mice with the most common and aggressive form of brain tumor, significantly extending their lives.

Stanford researchers identify normal cell type that gives rise to most invasive bladder cancers

A single type of cell in the lining of the bladder is responsible for most cases of invasive bladder cancer, according to researchers at the Stanford University School of Medicine.

Researchers discover new marker derived from human umbilical cord blood

The development of stem cell therapies to cure a variety of diseases depends on the ability to characterize stem cell populations based on cell surface markers.

Study proposes new model for understanding how proteins bind together to facilitate cell movement

Cell movement plays an important role in a host of biological functions from embryonic development to repairing wounded tissue. It also enables cancer cells to break free from their sites of origin and migrate throughout the body.

New technique of single-cell genomic analysis to reverse tissue engineering

Consider the marvel of the embryo. It begins as a glob of identical cells that change shape and function as they multiply to become the cells of our lungs, muscles, nerves and all the other specialized tissues of the body.

Researchers discover tumor suppressor gene folliculin essential to normal lung function in BHD patients

Researchers discover mechanism that control normal lung function in patients with BHD syndrome

Researchers at Penn Medicine have discovered that the tumor suppressor gene folliculin (FLCN) is essential to normal lung function in patients with the rare disease Birt-Hogg-Dube (BHD) syndrome, a genetic disorder that affects the lungs, skin and kidneys. Folliculin's absence or mutated state has a cascading effect that leads to deteriorated lung integrity and an impairment of lung function, as reported in their findings in the current issue of Cell Reports.

AVEO joins with Biodesix to develop and commercialize ficlatuzumab for treatment of NSCLC

AVEO Oncology (NASDAQ: AVEO) and Biodesix, Inc. today announced that they have entered into a worldwide agreement to develop and commercialize AVEO's hepatocyte growth factor (HGF) inhibitory antibody ficlatuzumab, with a Biodesix® companion diagnostic test.

Abnormal levels of lipid molecules can trigger autism during prenatal brain development

In a groundbreaking York University study, researchers have found that abnormal levels of lipid molecules in the brain can affect the interaction between two key neural pathways in early prenatal brain development, which can trigger autism.

Endurance sport keeps both muscles and nerves fit

Endurance sport does not only change the condition and fitness of muscles but also simultaneously improves the neuronal connections to the muscle fibers based on a muscle-induced feedback.

Cumulative amount of specific gene products affects changes in cell fate, say researchers

Johns Hopkins biologists have discovered that when biological signals hit cells in rhythmic waves, the magnitude of the cells' response can depend on the number of signaling cycles — not their strength or duration. Because such so-called “oscillating signaling cycles” are common in many biological systems, the scientists expect their findings in single-celled organisms to help explain the molecular workings of phenomena such as tissue and organ formation and fundamental forms of learning.

Research findings may be beneficial for creation of purer HSC lines for clinical treatments

Hematopoietic stem cells are now routinely used to treat patients with cancers and other disorders of the blood and immune systems, but researchers knew little about the progenitor cells that give rise to them during embryonic development.

Restless legs syndrome alters expression of critical gene during fetal development of brain

In a study published online in Genome Research, researchers of the Helmholtz Zentrum München und the Technische Universität München have demonstrated that a common genetic variant associated with Restless Legs Syndrome (RLS) alters the expression of a critical gene during fetal development of the brain.

Researchers create new line of human embryonic stem cells

Researchers at the University of Washington have successfully created a line of human embryonic stem cells that have the ability to develop into a far broader range of tissues than most existing cell lines.

3-D imaging of two different mouse models helps understand Apert Syndrome development

Three dimensional imaging of two different mouse models of Apert Syndrome shows that cranial deformation begins before birth and continues, worsening with time, according to a team of researchers who studied mice to better understand and treat the disorder in humans.

Sunburn causes melanoma through direct and indirect processes

Melanoma is particularly dangerous because it can form metastases in vital organs such as the lungs, liver or brain. UV radiation is considered to be the most significant triggering factor.

Researcher identifies ''conductor'' in development of muscle tissue

A team led by Jean-Fran-ois C-t-, researcher at the IRCM, identified a ''conductor'' in the development of muscle tissue. The discovery, published online yesterday by the scientific journal Proceedings of the National Academy of Sciences (PNAS), could have an important impact on the treatment of muscular diseases such as myopathies and muscular dystrophies.

Researchers examine how evolution relates to health

February 12 marks the birth of the 19th century naturalist Charles Darwin, who launched the scientific study of evolution. While Darwin's theory laid the groundwork, ongoing studies have deepened our understanding of evolution, including how it relates to health. Research funded by the National Institutes of Health has helped answer many questions about evolution, health and medicine. Here's a sampling.

EMT program in human cells may provide an effective approach for treating triple-negative breast cancer

A new study led by University of Kentucky Markey Cancer Center researcher Peter Zhou shows that targeting Twist, a nuclear protein that is an accelerant of the epithelial-mesenchymal transition (EMT) program in human cells, may provide an effective approach for treating triple-negative breast cancer.
