FIGURE 2.
Effects of rhEndostatin on osteoclast-like cell formation treated for different time periods. (A) Schematic of the experimental design for the in vitro experiments. BMMs were cultured in the presence of M-CSF and RANKL for 5 days, and rhEndostatin (50 mM) was added to the BMM cultures at the indicated days. (B) The number of TRAP-positive multi-nucleated cells were counted. The data are presented as percentages relative to the vehicle-treated control group. ∗∗P < 0.01 compared with the vehicle-treated control.
