Stem Cell Researchers Claim "Major Scientific Discovery"

Have shown stem cells can be made by dropping blood cells into acid

Stem cell researchers are heralding a "major scientific discovery", with the potential to start a new age of personalised medicine.

Scientists in Japan showed stem cells can now be made quickly just by dipping blood cells into acid.

Stem cells can transform into any tissue and are already being trialled for healing the eye, heart and brain.

The latest development, published in the journal Nature, could make the technology cheaper, faster and safer.
