Fig. 4: Comparison of thyrocyte ICAM-1 expression of thyroid xenografts between NIH-3 mice and SCID mice. ICAM-1 expression in both NIH-3 and SCID mice was significantly lower than basal (before xenografting) expression (Scheffé's test, p < 0.05). However, there was no significant difference between NIH-3 and SCID mice.
