Figure 1

Osteoclastogenesis is enhanced in vitro by CM from MSCs culture on BCP material. (A) Microscopic images of TRAP-stained osteoclasts culture without CM, with CM from MSC spheroids (Spheroid CM) or MSCs on BCP material (BCP CM). (B) Quantification by image analysis of TRAP+ area after 8 days of osteoclast differentiation with spheroid or BCP CM from three MSC donors, normalized to the TRAP+ area without CM. N = 3 independent experiments with technical triplicate. Statistical analysis by repeated measure ANOVA followed by Tukey’s multiple comparison test, *** for p value < 0.001, **** for p value < 0.0001.
