Axonal damage is the main characteristic of neurodegenerative diseases. This research was focused on remodeling cell morphology and developing a semi-tissue nanoenvironment via mechanobiological stimuli. The combination of nanogroove topography and polyaniline-chitosan enabled the manipulation of the cells by changing the morphology of PC12 cells to spindle shape and inducing the early stage of signal transduction, which is vital for differentiation. The nanosubstarte embedded with nanogooves induced PC12 cells to elongate their morphology and increase their size by 51% as compared with controls. In addition, the use of an electroconductive nanocomposite alongside nanogrooves resulted in the differentiation of PC12 cells into neurons with an average length of 193 μm for each axon and an average number of seven axons for each neurite. Our results represent a combined tool to initiate a promising future for cell reprogramming by inducing cell differentiation and specific cellular morphology in many cases, including neurodegenerative diseases.
