Migration of Schwann cells from the distal stump of the sciatic nerve 1 week after transection: the effects of insulin and cytosine arabinoside.

abstract：:RhoGTPases are molecular switches that integrate extracellular signals to perform diverse cellular responses. This ability relies on the network of proteins regulating RhoGTPases activity and localization, and on the interaction of RhoGTPases with many different cellular effectors. Myelination is an ideal place for Rh...
