Investigation of Neuronal Affinity to Photoresist Derived Carbon: Study of Diferentiation and m-RNA Expression in PC-12 Cells

Regenerative medicine holds promises for many neurodegenerative diseases such as Traumatic Brain Injury (TBI), a disorder that occurs when a sudden trauma causes damage to the brain, leading to apoptosis or necrosis of brain neurons. More than 5 million Americans suffer from TBI as a result of inability to regenerate damaged neurons. The aim of this project was to develop a biocompatible and electrically conductive substrate to promote growth and regeneration of neurons and for our long-term goal as a probe to record intracellular and multisite signals from brain. The substrate was fabricated by pyrolyzing a polymeric precursor -SPR 220.7 at temperatures higher than 700 ºC. Human Neuroblastoma cells - SK-N-MC, SY5Y and mouse teratocarcinoma cells P-19 were found to attach and proliferate on photoresist derived carbon film.
