Investigation of the effect of pamidronate disodium on the in vitro viability of osteosarcoma cells from dogs.

Objective: To determine the effect of pamidronate disodium on the in vitro viability of osteosarcoma cells and non-neoplastic cells from dogs.

Sample Population: 3 osteosarcoma and 1 fibroblast cell lines derived from dogs.

Procedure: Cell counts and cell viability assays were performed in cultures of osteosarcoma cells (POS, HMPOS, and COS31 cell lines) and fibroblasts after 24, 48, and 72 hours of incubation with pamidronate at concentrations of 0.
