DSPP and DMP-1 expression was assessed by Western blot using glyceraldehyde 3-phosphate dehydrogenase (GAPDH) as the loading control. Lane 1: control; lane 2: cells cultured on MBNs alone; lanes 3 and 4: cells cultured on MBN/GO 40:1 and 20:1, respectively for 7 days; lanes 5–8: cells cultured on MBN/GO 40:1 and 20:1, respectively for 14 days. Asterix (*) was not included in this experiment.
