title: [Influence of Mouse Spleen Microenviroment on T-ALL Progression].
abstract: OBJECTIVE
  To investigate the influence of spleen on disease status of mouse T-ALL.
  
  
  METHODS
  The leukemia cells were transplanted into the mice, then the development levels of leukemia cells in different organs of transplanted mice were monitored at different time points after transplantation; the transplanted leukemia cell level in different organs was detected by flow cytometry at different time points after transplantation; the survival of transplanted mice was analyzed by means of splenectomy.
  
  
  RESULTS
  The spleen change displayed most severely in process of T-ALL, the number of T-ALL cells in the spleen obviously increased at initial period. The detection of organs showed that along with the progression of leukemia, spleen weight change was the most significant, following by the lever change. The splenectomy test showed that the spleen played a promotive role in progession of T-ALL, and the spleneetomy could difinitely postpone the progression of T-ALL in mice, there was significant difference between splenectomy and non-splenectomy.
  
  
  CONCLUSIONS
  In early stage after transplantation of T-ALL cells, the spleen has the promotive effect on function of T-ALL cells, which suggests that the spleen may be a important microenvironment for T-ALL cell migrating into body.
