Comparable Effects of Strontium Ranelate and Alendronate Treatment on Fracture Reduction in a Mouse Model of Osteogenesis Imperfecta

<div>Effects of different treatments on bone resorption. (a) Representative images of TRAP staining in proximal tibia from different groups. (b, c) oim/Veh mice had higher bone resorption than wt/Veh mice, as reflected by higher osteoclast number (N.Oc/BS) and osteoclast surface (Oc.S/BS). (b) N.Oc/BS and (c) Oc.S/BS were significantly decreased with SrR or Aln treatment in both wt/wt and oim/oim mice. The N.Oc/BS and Oc.S/BS decreased to a greater extent with Aln treatment than with SrR treatment.
