  • a Latency is the time after BMT for mice to die or become moribund.

  • b Pleural effusion is 0.5 to 1 ml of unclotted, bloody fluid in the chest cavity, containing erythrocytes and many GFP-positive (GFP+) lymphoblastic cells.

  • c Thymic lymphoma was diagnosed by the presence of a greatly enlarged thymus (0.3 to 0.6 g).

  • d Phenotypes of GFP+ cells were determined by flow cytometry. ND, not determined.

  • e Pleural effusion appeared less bloody, with fewer erythrocytes and WBCs.

  • f Developed rear leg paralysis and elevated peripheral WBCs with >50% GFP+ lymphoblastic cells. No tumors, pleural effusion, or lung hemorrhages were seen.
