(A) A 12.4-kb fragment of BCL11A intron-2 (+52.0–64.4 kb from TSS) was cloned to a lacZ reporter construct. Transient transgenic mouse embryo from 12.5 dpc X-gal stained. Arrowhead indicates liver.
(B) Cell suspensions isolated from peripheral blood (PB) and fetal liver (FL) of stable transgenic embryos at 12.5 dpc X-gal stained.
(C) Sorted erythroblasts and B-lymphocytes from young adult stable transgenic mice subject to X-gal staining or RNA isolation followed by RT-qPCR. Gene expression normalized to GAPDH and expressed relative to T-lymphocytes. Error bars indicate s.d.
