Stem cells help researchers study the effects of pollution on human health

August 10, 2015 by · Leave a Comment 

A recent study published in the Journal of Environmental Sciences (JES) shows that embryonic stem cells could serve as a model to evaluate the physiological effects of environmental pollutants efficiently and cost-effectively.

Stem cells move one step closer to cure for genetic diseases

July 16, 2015 by · Leave a Comment 

Stem cells are key for the continual renewal of tissues in our bodies. As such, manipulating stem cells also holds much promise for biomedicine if their regenerative capacity can be harnessed. However, understanding how stem cells govern normal tissue renewal is a field still in its infancy.

Stem cells age-discriminate organelles to maintain stemness

April 3, 2015 by · Leave a Comment 

Tissue stem cells, that continuously renew our tissues, can divide asymmetrically to produce two types of daughter cells. One will be the new stem cell, where as the other will give rise to the differentiating cells of the tissue.

‘Master switch’ for myelination in human brain stem cells is identified

July 2, 2014 by · Leave a Comment 

Scientists at the University at Buffalo have identified the single transcription factor or “master switch” that initiates the critical myelination process in the brain. The research will be published online in Proceedings of the National Academy of Sciences (PNAS) on June 30.

MU scientists successfully transplant, grow stem cells in pigs

June 7, 2014 by · Leave a Comment 

One of the biggest challenges for medical researchers studying the effectiveness of stem cell therapies is that transplants or grafts of cells are often rejected by the hosts. This rejection can render experiments useless, making research into potentially life-saving treatments a long and difficult process. Now, researchers at the University of Missouri have shown that a new line of genetically modified pigs will host transplanted cells without the risk of rejection.

Racing the clock to help young patients with old hearts

May 20, 2014 by · Leave a Comment 

Children with progeria, a rare disorder that causes premature aging, die in their teens of ailments that are common in octogenarians: heart failure and stroke. Kan Cao, a University of Maryland assistant professor of cell biology and molecular genetics, urgently wants to help find a cure. Cao and her colleagues have taken a big step in that direction, showing that a toxic protein destroys muscle cells inside the patients’ arteries. The researchers suspect the damaged arteries are thus primed for failure.

New stem cell research points to early indicators of schizophrenia

May 14, 2014 by · Leave a Comment 

Using new stem cell technology, scientists at the Salk Institute have shown that neurons generated from the skin cells of people with schizophrenia behave strangely in early developmental stages, providing a hint as to ways to detect and potentially treat the disease early.
