Progenitor-restricted gene expression during C/EBPα-induced reprogramming. (A) Comparison of Affymetrix gene-expression values in different progenitors and in cells during reprogramming (gene names are shown above the line graphs). (B) qRT-PCR expression values of progenitor genes in cells during reprogramming. Values represent average plus SD of samples from three independent experiments. Positive controls are Lin−/Sca1+/Kit+ progenitors (LSK) and cultured bone marrow-derived macrophages (Mac), indicated by blue bars. (C) Timing of specific genes during reprogramming as determined by Nanostring technology. The highest values obtained in the different time points for each gene (Pax5, CD19, and Vpreb1 at 0 h: 2,046, 10,544, and 37,932, respectively; Kit at 12 h: 156; Flt3 at 24 h: 226; Ly6c at 48 h: 51,786; Mac1, Lyz2, and Fcgr1 at 120 h: 4,787, 36,563, and 23,221, respectively) were normalized to 100%.
