Since its creation in 2009, the Stamina Foundation, a private organization in Italy, has been claiming that stem cells collected from human bone marrow can be transformed into neural cells by exposure to retinoic acid, an important molecule in embryonic development. Stamina's founder Davide Vannoni, who has not trained as a scientist or physician, holds that injections with these cells can treat conditions as diverse as Parkinson's disease, muscular dystrophy and spinal muscular atrophy.
