Research Abstract

Our results indicated that bisphoshonate suppressed osteoblast differentiation and suggested that the anti-bone resorptive effect of bisphoshonate is not involved in RANKL expression of MSCs-derived osteoblast. We also found that GGOH strongly suppressed the bisphoshonate-induced apoptosis in MSCs.
