'Spray-on skin' helps heal leg ulcers
A "spray-on skin" which coats a wound with a layer of skin cells could help healing, according to US and Canadian researchers.
The spray was tested on 228 people with leg ulcers, which are painful open wounds that can last for months.
The findings, published in the Lancet, showed that ulcers treated with the spray were more likely to heal and did so more quickly.
Experts said faster healing could save money despite the cost of the spray.
