(G) Quantitative RT-PCR gene expression analysis of BCL11B in control (black bar), GATA3 shRNA or TCF7 shRNA (grey bars) transduced CD34+ thymocytes after 48h of coculture on OP9-DLL1 stromal cells, relative to the geometric mean of ACTIN and GAPDH and relative to the control-transduced sample (n=6 independent experiments with different donors for GATA3 shRNA, n=4 independent experiments with different donors for TCF7 shRNA, error bars indicate SEM and * indicates p<0.05 in a paired t-test).
