SMA Motor Neurons

Caption

In the right-hand picture is an SMA mouse treated with guanabenz, a compound known to reduce cellular stress, shows healthy junctions between muscle cells (red) and motor nerve fibers (green). In contrast, the untreated SMA mouse (left) has lost its nerve fibers, leaving the muscle cells with no way to receive signals from neurons in the spinal cord.
