Figure 3. Immunohistochemical detection of thymosin β4 in foetal and adult oesophagus.

Figure 3

a) Foetal oesophagus: the oesophageal lumen is coated with a thin Tβ4-immunoreactive layer (arrow). A weak reactivity for the peptide is observed in the muscular cells (arrowhead). (Original Magnification ×400) b) Adult oesophagus: immunoreactivity for Tβ4 is restricted to epithelial cells of the superficial layers (arrow). (Original Magnification ×400)
