A Little Acid Turns Mouse Blood Into Brain, Heart And Stem …

The heart beats in a mouse embryo grown with stems cells made from blood.

Back in 1958, a young biologist at Cornell University made a stunning discovery.

He took a single cell from a carrot and then mixed it with some coconut milk. Days went by and the cell started dividing. Little roots formed. Stems started growing. Eventually, a whole new carrot plant rose up from the single cell.

Imagine if you could perform a similar feat with animal cells, even human cells.

A team of Japanese biologists say they've taken a big step toward doing just that, at least in mice. Instead of using coconut milk, though, the magic ingredient is something akin to lemon juice.

Biologist Haruko Obokata and her colleagues at the RIKEN Center for Developmental Biology say they've figured out a fast, easy way to make the most powerful cells in the world embryonic stem cells from just one blood cell.

The trick? Put white blood cells from a baby mouse in a mild acid solution, Obokata and her team report Wednesday in the journal Nature. Eventually a few stem cells emerge that can turn into any other cell in the body skin, heart, liver or neurons, you name it.

For decades, scientists have been searching for easy ways to make human embryonic stem cells. These cells hold great potential for treating diseases such as Alzheimer's, Parkinson's, heart disease and diabetes.

But for a long time, human stem cells were essentially off limits for researchers because the only way to get them was by destroying human embryos.

Then in 2007, another team of scientists at the RIKEN center figured out a way to make human stem cells from skin and blood by manipulating the cell's genes.
