Localization and expression of R-cadherin in skeletal muscle following nerve injury.

Rats in which the sciatic nerves were cut were divided into two groups: animals with nerve sutured and animals with nerve not sutured. In the unsutured group, the levels of R-cadherin expression increased and then decreased to values lower than those of controls. In the sutured group, the levels of R-cadherin expression increased and then decreased to almost control values. These results suggest that R-cadherin plays some role in cells of normal and regenerating muscles.
