Under the microscope, a migrating neuron looks like a round cell perched on a rope, the glial fiber leading to its destination.

.... This study is looking at possible changes in the outer layer, or membrane of the muscle cell where dystrophin is normally found. When dystrophin is absent, the muscle cell does not work the same and eventually dies. The researchers will look at possible changes in the muscle membrane that may change the ......ting their zoo animals from a lofty perch: namely, outer space.
