Effect of TGFα-PE38 (T-PE) on hematopoietic stem cell (HSC) erythroid [burst forming unit-erythroid (BFU-E)] and myeloid [colony-forming unit-granulocytes, monocytes (CFU-GM)] progenitor colonies. HSCs were incubated with or without 5 ng/ml T-PE and/or CTLs at an effector-to-target ratio of 1.25 for 14 days. The number of BFU-E and CFU-GM were determined by a methylcellulose assay. There was no statistical difference in any group of BFU-E or CFU-GM compared with the other BFU-E or CFU-GM groups, respectively (Kruskal-Wallis test). Bars are standard error of the mean (n=2). Error bars are hidden in some of the data points. TGF, tumor growth factor; PE, Pseudomonas endotoxin; CTL, cytotoxic T lymphocytes.
