Skeletal muscle is a convenient model system for studying basic questions on the neural regulation of synaptogenesis and of many properties of sarcolemma and contractile apparatus. The study of the neural signals involved in a particular regulation and of the mediating intracellular pathways, requires the chronic application of drugs, second messengers, antibodies, trophic factors and the like. The most common way of application is in vitro treatment of muscle cell lines or primary myotube cultures. As an alternative to tissue culture, we developed a technique for in vivo application of the agents under study directly on skeletal muscle. An initial surgical step secures the tip of a fine polyethylene catheter (
