Human trials could begin within two to three years of tissue taken from specially bred pigs to help the millions of sufferers from diabetes, brain diseases and blindness.

In a review of xenotransplantation – using animal tissue and organs to replace human ones – experts from the Thomas Starzl Transplantation Institute at the University of Pittsburgh say the technology has made “great strides”.
