Fig. 5: Comparison of thyrocyte HLA-DR expression of thyroid xenografts between NIH-3 mice and SCID mice. HLA-DR expression in SCID mice was significantly lower than basal expression (Scheffé's test, p < 0.02); in contrast, there was no significant difference between expression in NIH-3 mice and basal expression. Moreover, HLA-DR expression in NIH-3 mice was significantly higher than in SCID mice (Scheffé's test, p < 0.05)
