Witryna5 lis 2008 · Murine ontogenic development of thymocytes in the thymus originates from precursor cells in the fetal liver that seed the thynic rudiment on day 10–11 of gestation [52, 53], and the fetal thymus contains significantly greater proportions of immature proliferating thymocytes than are present in corresponding adult models . The ... WitrynaWe recently characterised the NUP98-HOXD13 (NHD13) mouse as a model of T-cell pre-leukaemia, featuring thymocytes that can engraft in recipient animals and progress to T-cell acute lymphoblastic leukaemia (T-ALL). However, loss of this engraftment ability by deletion of Lyl1 did not result in any loss of leukemogenesis activity. In the present …
