Cell Assay
[1]

The frequency of chondrocyte apoptosis is measured by flow cytometry with Annexin V-fluorescein isothiocyanate (FITC) and propidium iodide. A total of 1×104 treated chondrocytes are collected from each group, washed in cold PBS and incubated with Annexin V-FITC and PI at room temperature for 15 min in the dark on ice. These samples are then analyzed using a fluorescence-activated cell sorter. Cell Quest software is used to analyze the percentage of apoptosis. All tests are repeated in triplicate.
