ApoPep-1 binds to apoptotic chondrocytes. a ATDC5 cells were incubated with staurosporine (0.5 μM) for 6 hours to induce apoptosis b ApoPep-1 binds to cells that bind to annexin V, a widely used in vitro marker for apoptosis. Cells were stained with ApoPep-1 (red), annexin V (green), and 4′, 6′ -diamidino-2-phenylindole (DAPI) (blue). Differential interference contrast (DIC) microscopy. Magnification, ×400
