Assessment of variability in the shape of the motor unit action potential, the "jiggle," at consecutive discharges.

abstract：INTRODUCTION:Skin-derived precursor cells (SKPs) are neural crest progenitor cells that can attain a Schwann cell-like phenotype through in vitro techniques (SKP-SCs). We hypothesized that SKP-SCs could produce mature myelin and, in doing so, facilitate the recovery of a focal demyelination injury. METHODS:We unilater...
