A third of people in the UK are unaware of stem cell donation, according to new research.
The tissues and blood from the umbilical cord in childbirth has been linked to helping treat leukaemia.
But according to research carried out by YouGov, most Britons don’t know if can be donated.
The international community is calling for these tissues to be donated or stored rather than thrown away to help further stem cell research.
Professor Francisco Dazzi from King's College London joins Wake Up London to explain how this can be done.
