FIGURE 4.

Disruption of microtubules and microfilaments and the presence of acidic or basic medium does not inhibit endocytosis of DSS by T44 cells. A and B, FITC-tagged DSS peptide endocytosis (green) is not inhibited by disruption of microtubules (A) and microfilaments (B). In both images red staining indicates microtubules and microfilaments respectively. C and D, DSS peptide endocytosis is not inhibited in the presence of acidic (C) and basic cell culture media (B). E, quantitation of fluorescence for DSS endocytosis in the presence of acidic and basic cell culture medium indicates the absence of endocytosis blocking. Data represent mean fluorescent signal ± S.E. (n = 9).
