Функциональный блок двигателя в культуре блюдо: Co-культуре эксплантов спинного мозга и мышечных клеток

Overview

This article describes a method to reproduce a functional motor unit in vitro by co-culturing differentiated human primary muscle cells with rat embryo spinal cord explants. This approach addresses the limitations of cultured muscle cells as models for innervated muscle in vivo.

Key Study Components
