The racing hero underwent stem cell therapy to help regenerate his nervous system following his life-changing skiing accident in 2013. He was treated by Professor Philippe Menasché, a world-renowned medical pioneer specialising in stem cell research at the Georges-Pompidou hospital in Paris, back in June. The doctor has previously managed to graft healthy stems cells onto the heart by replacing damaged ones with a healthy replacement.
Speaking to Express.co.uk, Dr Menasché revealed this treatment was suitable for Schumacher as it also helps people with brain injuries.
He said: “This is not a miracle treatment but there is pretty sound rationale behind it, so it is worth ethically testing with stem-cells.
“The cells used in the treatment are narrow, very robust and have anti-inflammatory properties.
“These can rescue damaged cells, caused by brain injuries, as their robustness helps with tissue protection.”
Dr Menasché added the treatment is not likely to cause any long term side effects.
He said: “There has been a recent study of 2,000 patients who received the treatment for a variety of diseases.
“There were no side effects and the treatment did not trigger a reaction.
“This means it is very safe.”

They were reportedly crossing an unsecured off-piste area down the Combe de Saulire above Meribel in the French Alps.
However, Schumacher fell while going down the slope.
He was airlifted to hospital for two operations after his ski helmet saved his life.
He was then placed in a medically induced coma in a stable condition for six months.
He began displaying “moments of consciousness” before being slowly taken out of the coma as doctors reported “small encouraging signs”.
Schumacher had regained consciousness by June and was then transferred to a hospital for rehab.
By September of that year, Schumacher was able to go home so he could recover in private.
Dr Menasché is understood to have first operated on Schumacher last September.
