'Junk DNA' drives embryonic development

An embryo is an amazing thing. From just one initial cell, an entire living, breathing body emerges, full of working cells and organs. It comes as no surprise that embryonic development is a very carefully orchestrated process—everything ...

How your DNA takes shape makes a big difference in your health

The more we learn about our genome, the more mysteries arise. For example, how can people with the same disease-causing mutation have different disease progression and symptoms? And despite the fact that it's been more than ...

Researchers find protein that suppresses muscle repair in mice

Researchers report that a protein known to be important to protein synthesis also influences muscle regeneration and regrowth in an unexpected manner. The discovery, reported in the Journal of Clinical Investigation, could ...

New technique shows promise for heart muscle regeneration

Researchers at Duke-NUS Medical School, Singapore, have developed an approach to regenerate heart muscle using stem cells. Their method for priming stem cells to become heart tissues could potentially enable heart regeneration ...

Surprising roles for muscle in tissue regeneration, study finds

A team of researchers at Whitehead has illuminated an important role for different subtypes of muscle cells in orchestrating the process of tissue regeneration. In a paper published in the November 22 issue of Nature, they ...

Tiny cellular antennae key to fat formation in muscle

Like it or not, as we age, our muscle cells are slowly exchanged, one by one, for fat cells. This process quickens when we injure a muscle, and an extreme form of this process is also seen in muscle-wasting diseases such ...

Gene controls regeneration of injured muscle by adult stem cells

A key gene enables the repair of injured muscle throughout life. This is the finding of a study in mice led by researchers at NYU Langone Medical Center and the University of Colorado at Boulder, and published online July ...
