Expression of CD68 by CD14⁺ splenocytes of patients with or without CLL.

Mononuclear splenocytes were stained for CD14 and CD68 and analyzed by flow cytometry. The figures provide representative histograms of gated CD14⁺ splenocytes from patients with (A) or without (B) CLL, depicting the fluorescence of cells labeled with an isotype control mAb (thin lines) or a mAb specific for CD68 (shaded histogram). The average MFIR for CD68 of CD14⁺ splenocytes from 2 patients (± SD) with (A) or without (B) CLL is indicated in the top right hand corner of each histogram.
