EDA^−/− mice have normal numbers of circulating leukocytes and proliferative capacity. (A) White blood cell counts from whole blood obtained from WT (n = 11) and EDA^−/− (n = 12) mice, analysed as described in the Materials and methods section. (B) Proliferative responses of WT and EDA^−/− splenocytes cultured in the presence or absence of 1 μg/ml concanavalin A (Con A) for 72 h measured by ³H-thymidine incorporation.
