Abstract: Disclosed is a bio-electrospinning technique for preparing a cell-containing, oriented, continuous tubular scaffold, made of biodegradable polymer, designed for use as a nerve guide conduit (NGC) in nerve regeneration. With a coaxial spinneret, the PC-12 cell medium solution was co-electrospun into a core of tubular fibers, with PLA on the outer shell. The resulted fibers' morphology was characterized via SEM and optical microscopy, and following structural characteristics were found: 1. the larger, hollow fibers had diameters in tenth of microns and wall thicknesses around few microns, 2. an orientation in a preferred direction with the aid of a high-rotating collection device. The fluorescent PC12 cells embedded within the scaffold were cultured and nerve growth factor was added. We observed cells could not only survive the process, but also sustain their viability by undergoing differentiation process, extending neurite along the micro tubular scaffold in the desired direction.
