The med (motor endplate disease) mouse phenotype appears at a crucial stage of the neuromuscular junction (NMJ) development. In the med mice, there is a drastic decrease in Terminal Schwann Cells (TSC) number, persistent multiple-innervation and a defect in synaptic maturation. All together these findings suggest that the med pathology is related to NMJ postnatal structural developmental defects probably triggered by the progressive loss of the TSCs and an ineffective synaptic maturation.
