Fig. 2. Tβ4 immunoreactivity in CaCo2 cells cultured for 48 h with 1% of DMSO (A), 15 mM of butyrate (B) and with 15 mM of butyrate and starvation conditions (C and D). Butyrate and starvation conditions are characterized by the presence of several vesicles (arrows). Note the presence of apoptotic cells (arrowhead). N = nucleus. C = cytoplasmic compartment. Bars = 20 μm.
