grp94 is preferentially expressed on plasma cells. a Human bone marrow cells were analyzed and representative FACS plots of different populations in MM. Histograms show the intracellular staining of grp94 on different populations (open histogram indicates grp94; shaded histogram, isotype control). Population I CD38⁻CD138⁻ cells (non-B cells), population II CD38^lowCD138⁻ cells (naïve B cells), population III CD38^intCD138⁻ cells (pro- and pre-B cells), population IV CD38^highCD138⁺ cells (plasma cells). b Quantification of grp94 expression in different populations of bone marrow from the patients with MM. Error bars indicate standard error of the mean. ***p < 0.001
