Interface experimental set-up. (A) Photograph of stainless steel interface mould; one 0.1 mm thick stainless steel divider is shown; however, up to three dividers could be inserted into the frame. Two culture populations in collagen gels were seeded either side of a steel divider, which was then removed after 2 min to allow gels to integrate. (B) Diagrammatic representation of one astrocyte:DRG interface gel. DRG, dorsal root ganglia. Color images available online at www.liebertonline.com/tec
