Formula One legend Michael Schumacher has reportedly been admitted to a French hospital to undergo a secret treatment.
Le Parisien newspaper reported that Schumacher has been in the hospital's cardiovascular surgery department since Monday and is in the care of cardiac surgeon Professor Philippe Menasché, who specialises in cell therapy to treat heart failure.
Little has been seen or revealed about the seven-time Formula One champion's condition since his skiing accident in the French Alps almost six years ago.
The report claimed that Schumacher has been benefiting from infusions of stem cells that are distributed in the body to obtain a systemic anti-inflammatory action.
