Erythroid differentiation is inhibited in human CD34+cells expressing RPS19 shRNAs. In panel A, mean glycophorin A (Gly-A) expression, assayed by flow cytometry, is shown as a percentage of the luciferase (luc) shRNA control (mean and SEM). In panel B, mean CD11b expression is displayed as a percentage of the control. Methylcellulose colony assays were performed with cells expressing control or RPS19 shRNAs. The number of BFU-E colonies is presented in panel C, and the number of CFU-GM colonies is presented in panel D (mean [SEM]). *P < .001 by 2-tailed Student t test; **P < .05.
