Researchers create first human heart cells that can be paced with light
In a compact lab space at Stanford University, Oscar Abilez, MD, trains a microscope on a small collection of cells in a petri dish. A video recorder projects what the microscope sees on a nearby monitor. The cells in the ...

Scientists convert skin cells to beating heart cells
Scripps Research Institute scientists have converted adult skin cells directly into beating heart cells efficiently without having to first go through the laborious process of generating embryonic-like stem cells. The powerful ...

Stem cells reverse blindness caused by burns
(AP) -- Dozens of people who were blinded or otherwise suffered severe eye damage when they were splashed with caustic chemicals had their sight restored with transplants of their own stem cells - a stunning ...

Embryo's heartbeat drives blood stem cell formation
(PhysOrg.com) -- Biologists have long wondered why the embryonic heart begins beating so early, before the tissues actually need to be infused with blood. Two groups of researchers from Children's Hospital ...

New study makes key finding in stem cell self-renewal
A University of Minnesota-led research team has proposed a mechanism for the control of whether embryonic stem cells continue to proliferate and stay stem cells, or differentiate into adult cells like brain, liver or skin.

New insight into the regulation of stem cells and cancer cells
Scientists at the Gladstone Institutes have gained new insight into the delicate relationship between two proteins that, when out of balance, can prevent the normal development of stem cells in the heart and may also be important ...

Newts' ability to regenerate tissue replicated in mouse cells
Tissue regeneration a la salamanders and newts seems like it should be the stuff of science fiction. But it happens routinely. Why can't we mammals just re-grow a limb or churn out a few new heart muscle cells as needed? ...

Study shows key enzyme in fetal heart development also involved in adult heart disease
Scientists at the Stanford University School of Medicine have identified for the first time an enzyme that plays vital roles in both fetal heart development and in causing cardiac hypertrophy — an enlargement of the heart ...
