Proliferation of T and B cells from naïve WT and Shp1-Tg mice following polyclonal stimulation. a T cells and b B cells of the three genotypes of naïve mice were isolated from the spleen and stimulated with anti-CD3/CD28 or anti-IgM antibodies, respectively. Cell proliferation was measured by [3H] thymidine incorporation and expressed as stimulation index (mean ± SEM, n = 3/group, *p < 0.05, **p < 0.01, ***p < 0.001; one-way ANOVA)
