in type 1 ( only one cell line , i.e. , caco-2 ) the cells undergo spontaneously an enterocytic differentiation characterized by a polarization of the cell layer with the formation of domes and the presence of an apical brush border the membrane of which is endowed with hydrolases such as sucrase-isomaltase , lactase , amino-peptidase n , dipeptidylpeptidase iv and alkaline phosphatase .
