Chondrosarcomas survives in alginate beads. Chondrosarcomas were embedded in alginate beads and viability were evaluated for several weeks. a Metabolic activity was evaluated by ATP assay using Cell Titer-Glo luminescent cell viability assay kit (Promega). For each cell line, values were normalized to luminescence values obtained at day 1. Graph shows means ± SEM of 4 independent beads. b Viable cells inside beads were also counting. Cell number was normalized to values obtained at day 1. Graph shows means ± SEM of 3 independent experiments
