The permeability analysis of the jejunum and colon of mice. (a) The ultrastructure of the jejunum and colon examined by transmission electron microscopy. TJ: tight junction; AJ: adherens junction; DS: desmosomes. . (b) The permeability assessment of the jejunum and colon by tracer experiments. The green fluorescence signals indicate biotin distribution; the red arrows indicate tracer leakage. .
