3-D packaging of DNA regulates cell identity

The fundamental mechanisms governing how cells form an identity such as becoming a muscle cell or a nerve cell are not fully understood. Multiple diseases, including cancer, have been linked to cells going down the wrong ...

Light-activated skeletal muscle engineered (w/ Video)

Many robotic designs take nature as their muse: sticking to walls like geckos, swimming through water like tuna, sprinting across terrain like cheetahs. Such designs borrow properties from nature, using engineered materials ...

Special cells contribute to regenerate the heart in zebrafish

It is already known that zebrafish can flexibly regenerate their hearts after injury. An international research group led by Prof. Nadia Mercader of the University of Bern now shows that certain heart muscle cells play a ...

Stay out, stray stem cells

Despite the hubbub about pluripotent stem cells' potential applications, when it comes time to introduce products into patients, the stem cells are actually impurities that need to be removed.

Scientists identify critical enzyme in healthy heart function

Scientists are reporting the first-ever data to show that the enzyme calcineurin is critical in controlling normal development and function of heart cells, and that loss of the protein leads to heart problems and death in ...

High vinculin levels help keep aging fruit fly hearts young

Our cells tend to lose their shape as we grow older, contributing to many of the effects we experience as aging. This poses particular problems for the heart, where aging can disrupt the protein network within muscle cells ...

How do you mend a broken heart?

Damaged heart tissue is not known for having much inherent capacity for repair. But now, scientists are closing in on signals that may be able to coax the heart into producing replacement cardiac muscle cells. Using a zebrafish ...
