Coverage of the latest news and updates from the field of stem cells.
Researchers have learned that precursor cells for skeletal muscles actually also give rise to neurons, blood vessels, blood cells and immune cells, pushing science one step closer to generating body parts in a laboratory.
The human body develops most tissue types during fetal development, in a mother’s uterus. Yet one only tissue develops after birth: the mammary gland.
An automated system that uses robots has been designed to rapidly produce human mini-organs derived from stem cells. Researchers at the University of Washington School of Medicine in Seattle developed the new system.
Researchers at University of California San Diego School of Medicine and their collaborators have developed a technique that allows them to speed up or slow down human heart cells growing in a dish on command — simply by shining a light on them and varying its intensity.
The U.S. Food and Drug Administration (FDA) filed complaints in federal court on May 9 seeking permanent injunctions to stop two stem cell clinics from marketing stem cell products without FDA approval and for significant deviations from current good manufacturing practice requirements.
More than 27 million people in the United States are living with type 2 diabetes, according to the Centers for Disease Control and Prevention. As the population ages and a growing percentage of people become overweight or obese, that number is expected to increase.
The production of blood cells is regulated by so-called hematopoietic stem cells (HSCs), which reside in bone marrow. Under certain stress conditions, such as aging or inflammation, the HSCs’ self-renewal capacity — a key property of stem cells — decreases.
For most people with hemophilia B, whose bodies can’t properly form blood clots, constant injections to replenish their clotting factors are a way of life.
As people age, their intestinal stem cells begin to lose their ability to regenerate. These stem cells are the source for all new intestinal cells, so this decline can make it more difficult to recover from gastrointestinal infections or other conditions that affect the intestine.
