Using PC12 cells to evaluate poly(caprolactone) and collagenous microcarriers for applications in nerve guide fabrication.

Tissue-engineered nerve guides can provide mechanical support as well as chemical stimulation for nerve regeneration. PC12 cells were used to test the novel combination of poly(caprolactone) (PCL) and macroporous collagen-based microcarriers (CultiSphers) as an initial phase in the fabrication of multichanneled nerve guides. Laminin-coated PCL was an effective matrix for the attachment, proliferation, and viability of PC12 cells, relative to uncoated PCL.
