Fig. 1From: Knockdown of CD44 inhibits proliferation, migration and invasion of osteosarcoma cells accompanied by downregulation of cathepsin SCD44 and cathepsin S are upregulated in OS cell lines. A, B CD44 protein levels in MG63, U2OS, and hFOB 1.19 cell lines. **P < 0.01 versus hFOB group. C CD44 mRNA levels in MG63, U2OS, and hFOB 1.19 cell lines. **P < 0.01 versus hFOB group. D Cathepsin S mRNA levels in MG63, U2OS, and hFOB 1.19 cell lines. **P < 0.01 versus hFOB groupBack to article page
