VDR KO mice have blood in the colon and altered white blood cell values compared to WT mice. A) Colonic blood score as a function of time post-DSS. Two WT and 2 VDR KO mice were sacrificed each day after 2.5% DSS administration and colonic blood score was assessed as described in the Materials and Methods. B) Hematological changes in WT and VDR KO mice following 2.5% DSS administration. Error bars represent ± SEM. * WT and VDR KO values were significantly different.
