title: CD3- bone marrow cells augment the generation of cytotoxic T lymphocytes showing a preference for the X-chromosome linked gene product of stimulator cells.
abstract: Responder cells, composed of both a limited number of nylon wool-passed lymph node (NW-LN) cells and an excess number of CD3+ cell-depleted bone marrow (CD3- BM) cells from the same strain of mice, were stimulated with allogeneic spleen cells in vitro. The CD3- BM cells augmented the generation of allogeneic major histocompatibility complex (MHC) class I specific cytotoxic T lymphocytes (CTL) from NW-LN cells. C3H/He (H-2k, C3H background) responder cells were stimulated with either B10.D2 (H-2d, B10 background) or BALB/c (H-2d, BALB background) spleen cells. In the former stimulation, the CTL induced lysed B10.D2 target cells more efficiently than the BALB/c cells. Furthermore, these CTL lysed more (B10.D2 x BALB/c) F1 male target cells than (BALB/c x B10.D2) F1 male. In the latter stimulation, the CTL lysed more BALB/c than B10.D2 cells, and more (BALB/c) x B10.D2) F1 male than (B10.D2 x BALB/c) F1 male. The reciprocal mixed lymphocyte cultures (MLC) were carried out, in which BALB/c responder cells were stimulated with either C3H/He or B10.BR (H-2k, B10 background) spleen cells. In the former stimulation, the CTL induced lysed more C3H/He or (C3H/He x B10.BR) F1 male target cells than B10.BR or (B10.BR x C3H/He) F1 male, and in the latter, the reciprocal results were obtained. These results suggested that the CTL induced had a preference for the X-chromosome linked gene products (Xlgp), besides the specificity for the allogeneic MHC class I, of the mice used as stimulator.
