Micro-patterning of growth plate chondrocytes on a PPE:N-coated surface. Kapton^® polyimide masks (100 μm openings, 200 μm pitch) were placed over the BOPP substrate to create the pattern. Growth plate chondrocytes grown on this patterned surface for 9 days and photomicrographs were taken (A). Proteoglycan production was visualized using Safranin-O staining (B).
