Objective To evaluate the influence of electrospun poly(methyl methacrylate) (PMMA) nanofibers with different topographic features on neurite growth and orientation of PC12 cells. Methods Electrospun PMMA nanofibers with random or aligned topographic features were produced and PC12 cells were cultured on them. The biocompatibility of the fibers was evaluated. With PMMA film as control
the neurite growth ability and orientation of PC12 cells were assayed using lentivirus-mediated green fluorescent protein transfection. Results The electrospun PMMA nanofibers had good biocompatibility
and could exert contact guidance to the neurite growth of PC12 cells. On aligned nanofibers
PC12 cells could form neuritis with greater length and better alignment
as compared to random nanofibers and films (length: 85.7±39.8 vs 64.1±32.5 vs 60.2±29.9 μm). Conclusion Aligned electrospun PMMA nanofibers can be used as a potential cell scaffolding after neural injury.
