Figure 1. Inhibition of RANKL-induced osteoclast differentiation by CL. (A) Corylin structure chemically. (B) Cell viability of CL on BMMs at day 1, day 3, day 5, and day 7. (C) The TRAP staining image from BMMs treated with CL under osteoclast induction condition. (D, E) The number and area quantifying of mature osteoclast. The ns, not statistically significant; **P < 0.01; ***P < 0.001; ****P < 0.0001.
