Abstract: Advanced tissue engineering requires scaffolds fabricated at different scales to facilitate cellular repair. Neurons respond to micro and nanopatterns over which are grown and it is possible to control – to some extent –
neurite protrusion and the formation of neuronal network by using only nanopatterns. The present proposal is based on four main steps:
i – Development and fabrication of Scaffolds;
ii – Experimentation and testing of the formation of 3D neuronal networks;
iii – Analysis of long term survival of 3D neuronal networks;
iv- Development and testing of scaffolds for implants.
The final and most important step concerns the implantation of our scaffolds in a neuronal tissue for repair. We will attempt to implant our scaffolds for repairing spinal cord and sciatic nerve injuries, a realistic but challenging aim
