Real-time PCR of PDL cells seeded with HA_ncl and HA_cl treatment for genes encoding (a, b) Runx2, (c, d) Collagen 1 alpha 2 (COL1a2), (e, f) alkaline phosphatase (ALP) and (g, h) osteocalcin (OCN) at 7 days post seeding. Cells were treated (a, c, e, g) in regular growth medium or (b, d, f, h) with ODM. (* 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)
