Figure 8. High IBSP expression is associated with poor survival. (A) The prognostic significance of IBSP expression was validated by RT-PCR with another cohort consisting of 21 living patients and 11 deceased patients. (B) The protein expression of IBSP by IHC staining. Scale bar = 50 μm (left panel); scale bar = 20 μm (right panel). *P < 0.05.
