Scientists have shown that stem cells delivered to rats via a nasal spray lead to an improvement of motor functions in rats with Parkinson’s disease like symptoms.
Mesenchymal stem cells sprayed into the rat noses migrated to the brain and survived for at least 6 months. Dopamine levels increased in previously damaged areas and motor functions improved up to 68% of normal in the stem cell treated rats.
