Paralysed rats treated with a cocktail of embryonic stem cells, adult stem cells, proteins and drugs have recovered some movement, say researchers at Johns Hopkins University in Baltimore. Lead researcher Dr Douglas Kerr says that the work is a big step forward towards a cure for spinal cord injury and other kinds of paralysis; clinical trials might be possible within five years. He said the big limitation was lack of federal funding — hundreds of millions will be needed to bring the development through to clinical trials.
