Induced proliferation of ‘BFU-E like’ cells by over-expression of the transcription factor c-Myc. Shown are measurements from 3 separate in vitro experiments where cells were modified by stable gene transfer of the TRE3G-cMyc vector, cultured in puromycin to eliminate non-modified cells (except wild type condition), then cultured with 2000 ng/ml dox for expression of the vector gene of interest or no dox as a control
