Phagocytosis of fluorescently labeled E.coli by CD34+ derived macrophages: E. coli Bioparticles® were added directly to the cultured macrophages along with 5 μg/ml LPS. Twenty four hours post-stimulation, cells were analyzed by FACS. (A) Control macrophages without Bioparticles®. Panels B-E show plots of cells incubated with Bioparticles® (B) Transduced Magi-CXCR4 (non-phagocytic cell culture), (C) nontransduced, (D) GFP-alone, and (E) XHR macrophages. These data are representative of triplicate experiments.
