The aim was to evaluate the ionic product of 60S bioglass (BV60S) in osteogenic differentiation of mesenchymal stem cells from adipose tissue (ADMSCs) in dogs. ADMSCs were differentiated without the ionic product (OST) and with the ionic product (PI-OST) for 7, 14 and 21 days. We evaluated the MTT, alkaline phosphatase (ALP), collagen mineralization and expressions of osterix (OSX), bone sialoprotein (BSP), osteonectin (ON) and osteocalcin (OC). The PI-OST group had a lower MTT conversion to 7days and higher conversion at 21 days. The ALP activity was higher in the OST group at 14 and 21 days. Collagen synthesis was higher in the OST group at 7 and 21 days. A higher mineralized area in the PI-OST group was observed at all times. There were no differences in expressions of OSX and OC between groups. We observed increased expression of BSP in the PI-OST group at 14 and 21 days. The expression of ON was higher in the OST group at 14 days. It was concluded that the ionic product of BV60S promotes in vitro osteogenesis of MSC-AD from dogs.
