Using a combination of computational modeling and experimental techniques, a research team has developed new information about how intercellular communication affects the differentiation of an embryonic stem cell
Cells’ metabolic needs are not uniform across the brain, researchers have learned. “Knocking out” an enzyme that regulates mitochondria, cells’ miniature power plants, specifically blocks the development of
The definitive architecture of the mammalian body is established shortly after implantation of the embryo in the uterus. The antero-posterior, dorso-ventral and medio-lateral axes of the body become
Key insights into how sperm and egg cells are formed have been discovered by scientists, shedding light on the earliest stages of their development. The research shows for
Researchers at Ruhr-Universität Bochum and the University of Tübingen have gained new insights into the structure of the killer protein Bax. The protein induces programmed cell death, the
Organs affected by autoimmune disease could be fighting back by “exhausting” immune cells that cause damage using methods similar to those used by cancer cells to escape detection,
St. Jude Children’s Research Hospital investigators have unraveled the origins and identified mutations associated with a perplexing form of acute leukemia. The landmark study appears today as an
New research suggests that obesity changes how airway muscles function, increasing the risk of developing asthma. The study is published ahead of print in the American Journal of
The mechanics behind how an important process within the cell traps material before recycling it has puzzled scientists for years. But Penn State researchers have gained new insight
Glaucoma, a disease that afflicts nearly 70 million people worldwide, is something of a mystery despite its prevalence. Little is known about the origins of the disease, which
