A new way of growing human embryonic stem cells in the laboratory will reduce the risk that their use in therapy could go wrong, say scientists.

At present the cells are cultured using live animal cells, which carries the risk of contamination with viruses and other harmful agents. Researchers at Advanced Cell Technology in Boston have developed a method that replaces the use of animal cells with a sterile protein matrix.
