Figure 3: RT1-A silencing promotes graft survival in allogeneic transplantation. (a) Mean tumor volume. (b) Percentage of graft survival after allogeneic transplantation. Cell engraftment and tumor growth were monitored for 8 weeks after allogeneic transplantation by palpation and bioluminescence. All animals in the haplotype-matched transplantation groups receiving RT1-A-expressing or RT1-A-silenced cells were sacrificed 2 weeks after transplantation to prevent morbidity due to excessive tumor growth.
