thus , in villus goblet cells of rat small intestine ( a ) mucous granule membranes and the apical plasma membrane with which they fuse during secretion appear strikingly enriched with cholesterol , ( b ) cholesterol appears to be incorporated into mucous granule membranes during and shortly after their formation at the golgi trans-face , and ( c ) the cholesterol content of the lateral plasma membrane of secreting goblet cells appears to be greater than that of nonsecreting cells .
