Mice with transgenic T cell receptor (TCR) recognizing H-Y male antigen developed spontaneous lymphomas originated from immature thymocytes, with the surface expression of transgenic TCR and CD4/CD8 co-receptors. During in vitro long-term culture (3 months) some lymphoma cell lines lost the surface expression of TCR and co-receptors. Interestingly, the proteins of transgenic receptor were expressed intracellularly but TCR was not detectable on the surface of the in vitro selected subline in contrast to TCR-positive parental cells maintained in vivo. TCR-negative subline has been found to be slowly growing in vivo (i.p. injection) and less tumorigenic (s.c. injection) than parental TCR positive lymphoma. It seems that the in vivo interactions of lymphoma cells with microenvironment preserve their TCR expression and endow with growth advantage, while the selected in vitro TCR-negative cells lose the tumorigenic potential.
