FIG 2.
RELM-β deficiency alters transepithelial barrier permeability. A, Transepithelial resistance of colonic segments of muscle-free intestinal mucosa from WT and RELM-β-/- mice. B, FITC-dextran (molecular weight 4400) permeability in muscle-free intestinal mucosal specimens from the colon from WT and RELM-β-/- mice. Values are presented as means 6 SEM (n 5 3-8 mice per group). Statistical significance of differences was determined by using an unpaired Student t test. *P < .05 compared with WT mice.
