(Medical Xpress)—Despite early optimistic studies, the promise of curing neurological conditions using transplants remains unfulfilled. While researchers have exhaustively cataloged different types of cells in the brain, and also the largely biochemical issues underlying common diseases, neural repair shops are still a ways off. Fortunately, significant progress is being made towards identifying the broader operant principles that might bear on any one disease work-around. A review just published in Science focuses on recent work on transplanting interneurons—a diverse family of cells united by their mutual love of inhibition and their local loyalty. The UCLA-based authors, reach the conclusion that the fate of transplanted neurons ultimately depends less on the influences of the new host environment, and more on the early upbringing of the cells within the donor embryo.
