Effect of inflammatory cytokines on erythroid cell growth. (a) Growing erythroid cells (gECs) 5-days old were treated with various concentrations of TNF-a (white bars) or IFN-g (grey bars) and cultured for an additional three days. * P < 0.01 compared with medium control. (b) TNF-a (white bars) and IFN-g (grey bars) in erythroid culture activated by intact IEs or UEs; lysates of IEs or UEs; and 25 ng/ml of TNF-a as a positive control were determined using the Bio-Plex Pro™ Magnetic Cytokine assay. The error bars show the S.D. from three independent experiments.
