Stem cell breakthrough may be simple, fast, cheap

CNN) -- We run too hard, we fall down, we're sick -- all of this puts stress on the cells in our bodies. But in what's being called a breakthrough in regenerative medicine, researchers have found a way to make stem cells by purposely putting mature cells under stress.

Two new studies published Wednesday in the journal Nature describe a method of taking mature cells from mice and turning them into embryonic-like stem cells, which can be coaxed into becoming any other kind of cell possible. One method effectively boils down to this: Put the cells in an acidic environment.

"I think the process we've described mimics Mother Nature," said Dr. Charles Vacanti, director of the laboratory for Tissue Engineering and Regenerative Medicine at Brigham & Women's Hospital in Boston and senior author on one of the studies. "It's a natural process that cells normally respond to."

Both studies represent a new step in the thriving science of stem cell research, which seeks to develop therapies to repair bodily damage and cure disease by being able to insert cells that can grow into whatever tissues or organs are needed. If you take an organ that's functioning at 10% of normal and bring it up to 25% functionality, that could greatly reduce the likelihood of fatality in that particular disease, Vacanti said.........
