Figure 4. Detection of expressions of relevant proteins in osteoclasts via Western blotting. LP45 inhibits osteoclast formation by modulating histone proteases in macrophages and secreting exosomes to osteoclasts. (A) Detection of expressions of relevant proteins in osteoclasts via Western blotting. (B) Expression levels of relevant proteins in osteoclasts. **p < 0.05, Abbreviation: ns: no statistically significant difference.
