April 22nd from Medical Press, “Parkinson’s disease is a neurodegenerative disorder characterized by the death of dopamine-producing neurons in the midbrain, resulting in motor symptoms such as tremors and stiffness. The cause of cell death remains unknown and researchers have long sought a way to replace the lost dopamine-producing cells. A study led by Takuya Hayashi from the RIKEN Center for Molecular Imaging Science now suggests that in monkeys such neurons can be derived from bone marrow stem cells and then transplanted back into the brain to reverse the symptoms of this devastating disease.”
