Fig. 4. Reexpression of Gata3 suppresses B and myeloid development in Tcf1 deficiency.

Fig. 4

(A) Layout of retroviral complementation experiments with GFP control and/or Gata3. (B) Gata3 expression partially overcomes the DN1 thymocyte block and (C) suppressed the enhanced non-T cell lineages (B and myeloid cell development) after 7 days in the OP9-DL1 culture system. FACS shows representative plots and graphs quantitative data from replicate measurements. (Multiple t test analysis. Error bars represent the SD from two independent experiments.) (D) In vivo complementation [Ly5.2 Tcf1 (WT or KO)–transduced stem cells transplanted into Ly5.1 recipient mice] reveals suppression of B cell development also in the thymus (right) 8 weeks after transplantation but minimal and partial rescue of T cell development in the thymus (left and middle). (Middle: Multiple t test analysis. Right: Paired t test. Error bars represent the SD from three individual mice per group.)
