Microchannels were produced using a photolithographic technique to pattern polyimide walls (11 microm in height and 20-60 microm in width) onto a planar glass substrate. PC12 cells were seeded onto patterned surfaces. After 3 days of culture in NGF supplemented medium cells were viable and extended neurites. Culture in microchannels influenced the direction(More)
Growth factors have been widely used in strategies to regenerate and repair diseased tissues, but current therapies that go directly from bench to bedside have had limited clinical success. We hypothesize that engineering successful therapies with recombinant proteins will often require specific quantitative information of the spatiotemporal role of the(More)
