Figure 3. Serial transplantation of Tet2-mutant fetal liver cells.
(A) WT and Tet2-mutant FL cells (Ly5.2) were transplanted into lethally irradiated recipients (Ly5.1), and percentages of donor chimerism in recipient's PB were analyzed by flow cytometry at the indicated time points after transplantation. Serial transplantations were performed as described in Methods. The data represents the mean ± S.D. (1st transplantation; Tet2+/+: n = 4, Tet2+/gt and Tet2gt/gt: n = 5, 2nd and 3rd transplantation; Tet2+/gt: n = 4, Tet2+/+ and Tet2gt/gt: n = 5). (B) (Upper panel) Flow cytometric analysis of donor derived HSC fraction (CD34−LSK cells) within Lin− fraction of BM mononuclear cells in mice receiving the first transplants. Representative FACS pictures are shown. (Lower panel) Percentages of donor derived CD34−LSK cells within Lin− fraction of BM mononuclear cells in mice receiving the first transplants. The data represents mean ± S.D. (n = 3 for each recipient).
