Spinal cord injury (SCI) is a serious trauma, which often results in a permanent loss of motor and sensory functions, pain and spasticity. Despite extensive research, there is currently no available therapy that would restore the lost functions after SCI in human patients. Advanced treatments use regenerative medicine or its combination with various interdisciplinary approaches such as tissue engineering or biophysical methods. This review summarizes and critically discusses the research from specific interdisciplinary fields in SCI treatment such as the development of biomaterials as scaffolds for tissue repair, and using a magnetic field for targeted cell delivery. We compare the treatment effects of synthetic non-degradable methacrylate-based hydrogels and biodegradable biological scaffolds based on extracellular matrix. The systems using magnetic fields for magnetically guided delivery of stem cells loaded with magnetic nanoparticles into the lesion site are then suggested and discussed.
