Mitochondrial depolarisation in OF and OA chondrocytes. Percentage depolarisation of OA or OF femoral heads and comparison between areas (SP and IP). (a, b) OF cartilage. (a) and (b) show results of chondrocytes from SP and IP zones, respectively. (c, d) OA cartilage. (c) and (d) show results of chondrocytes from SP and IP zones, respectively. (e) Quantification of mitochondrial depolarization. No differences were found between areas for either set of cartilage conditions. *Significant differences were found between OA and OF cartilage. IP, inferior pole; OA, osteoarthritis; OF, osteoporotic fracture; SP, superior pole.
