The table shows the results of cell coating on the surface of FNTD crystals using different cell lines with and without a fibronectin intermediate layer. Each well contained 500 μl. Cell culture medium was exchanged every 48 h. (*) Proliferation rate is lower compared to cells grown on the untreated bottom of a culture well.
