Figure 2

a) Foetal tongue: the superficial epithelial cells (arrow) shows a diffuse immunoreactivity for Tβ4, localized in the cytoplasm. The underlying corion is negative. (Original Magnification ×250) b) Adult tongue: the superficial layers of the stratified epithelium show a strong diffuse cytoplasmic reactivity for Tβ4 (arrow). (Original Magnification ×250)
