Alkaline phosphatase staining of PDL cells treated by HA_ncl and HA_cl (a) in growth medium or (b) within ODM at 7 days post seeding. Both HA_ncl and HA_cl significantly decreased ALP staining without ODM while with ODM both HA_ncl and HA_cl significantly increased ALP staining when compared to control samples (* denotes significant difference, p < 0.05; # denotes significantly lower than control, p < 0.05; † denotes significantly higher than control, p < 0.05; ** denotes significantly higher than all other treatment modalities, p < 0.05)
