Figure 7. Over-expression of TRAIL increases osteoclastogenesis.

Figure 7

(a) Ground based control RAW 264.7 cells were transfected with empty vector (EV) or TRAIL expression vector (pTRAIL) and over-expression of TRAIL was confirmed after 48 h by western blot. β-actin expression served as control; (b) cultured for OCL formation. (c) TRAP-positive multinucleated OCLs formed at the end of the culture period were scored under microscope. *Significant (P < 0.05) difference when compared to EV.
