The Mouse Mesenchymal Stem Cell Functional Identification Kit (R&D Systems, Inc. Minneapolis, MN, USA) was used for multipotency evaluation of BM-MSC to differentiate osteoblasts and adipocytes. First, adipocytes were dyed with oil O red to demonstrate lipid droplets. Osteocytes were dyed with Von Kossa to demonstrate bone matrix deposits. BM-MSC culture without differentiation was used as the negative control. Adipocytes and macerated rat bone were positive controls for oil O red and Von Kossa, respectively.
