Effect of growth factors and extracellular matrix materials on the proliferation and differentiation of microencapsulated myoblasts

An alternative approach to gene therapy via non-autologous somatic gene therapy is to implant genetically-engineered cells protected from immune rejection with microcapsules to deliver a therapeutic gene product. This delivery system may be optimized by using myoblast cell lines which can undergo terminal differentiation into myotubes, thus removing the potential problems of tumorigenesis and space restriction. However, once encapsulated, …
