grp94 is highly expressed on malignant plasma cells in MM. a Quantification of grp94 expression in the plasma cells from the patients with MM, MGUS/SMM, and NPC. Error bars indicate standard error of the mean. *p < 0.05, **p < 0.01, ***p < 0.001. b Quantification of CD138 expression in the plasma cells from the patients with MM, MGUS/SMM, and NPC. Error bars indicate standard error of the mean. **p < 0.01, ***p < 0.001. c Correlations between grp94 expression and CD138 expression in plasma cells from patients with MM (left panel) and patients with MGUS/SMM (right panel)
