Methods Swine AD- MSCs were isolated from fat tissue with collagenase, followed by induction of differentiation to osteogenic, adipogenic and chondrogrnic cells. The survival curve of the ADMSC at the 37℃ and 38℃ were measured using WST-1 Cell Proliferation Assay Reagent. Result ADMSCs isolated with collagenase from swine neck fat tissue generated a stable uniform appearance af- ter the second generation. The passage period was five days. ADMSC could differentiate into osteogenic, adipogenic or chon- drogrnic cells under different culture conditions. The highest growth rate was achieved at 38℃in this study. Conclusion Swine ADMSCs have the potential to differentiate into osteogenic, adipogenic or chondrogrnic cells, and they may be appropriate for transplantation for both research and clinical purpose.展开更多
