Abstract Brain and spinal cord injury are a serious traumata and despite intensive research, there is still no effective treatment for patients. One of the studied approaches is to use various biomaterials to repair the damaged neural tissue. The aim of this thesis is to study the regenerative and neurotrophic effects of injectable extracellular matrix (ECM) hydrogels prepared by decellularization from porcine tissue (brain, spinal cord, bladder) and human umbilical cord (UC) in reconstruction of damaged neural tissue of the brain and spinal cord in rats. We characterized ECM hydrogels in terms of mechanical and rheological properties, structure and composition, cell adhesion, migration and proliferation. In a model of spinal cord hemisection, we compared the regenerative effect of ECM hydrogels derived from porcine spinal cord and urinary bladder. We found no benefits of tissue specific ECM prepared from the tissue of neural origin in terms of its neurotrophic properties in vitro or in vivo....
