Figure 8. Immunohistochemical detection of thymosin β4 in foetal and adult pancreas.

Figure 8

a) Foetal pancreas: immunoreactivity for Tβ4 is localized inside the islets of Langherans. Some of endocrine cells show the entire cytoplasm strongly immunoreactive for the peptide (arrows). Few Tβ4-reactive cells are also present in the exocrine pancreas, inside the tubular structures (arrowhead). (Original Magnification ×400). b) Adult pancreas: the highest reactivity for Tβ4 is observed in Langherans islet cells, which show diffuse fine granular deposits in their cytoplasm (arrows). (Original Magnification ×400).
