title: Using PC12 cells to evaluate poly(caprolactone) and collagenous microcarriers for applications in nerve guide fabrication.
abstract: 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. PC12 cells attached to laminin-coated PCL and extended neurites when cultured in the presence of nerve growth factor (NGF). PC12 cells attached and proliferated on CultiSphers and extended neurites in response to NGF. A novel PCL/CultiSpher composite material also supported PC12 attachment and proliferation and provides a potentially useful material for the fabrication of synthetic nerve guides.
