Bone marrow fusion with nerve cells may repair damage, Stanford researchers say
...lps resolve an ongoing debate: Do adult stem cells transform from bone marrow cells into other cell types, such as brain, muscle or liver cells, or do they fuse with those cells to form a single entity with two nuclei? The research shows that for complex brain cells called Purkinje cells, fusion is the normal ......lled brainmachine interfaces (BMIs), programmed to transform neural impulses into signals that can control a robotic device.
