...). TEM of the extracted epithelium in situ reveals IF bundles beneath the apical cell surface, around the nucleus and at the lateral edges of the cells where association with desmosomes occurs. IF bundles are also very prominent within basal cell processes where they loop through the cytoplasm adjacent...

... types started at 4 days postnatally with keratin 7 localizing to basal cells. Five days after birth, keratins 5 and 14 were also localized to the basal epithelium, while keratins 8 and 18 were only expressed by luminal cells. Keratin 19 was expressed in all epithelial cells throughout development...

...G.R. Cunha; S.W. Hayward; R. Dahiya; B.A. Foster A hypothesis is proposed that unifies prostatic developmental biology and carcinogenesis. The foundation of this hypothesis is the reciprocal interaction of epithelium and mesenchyme during prostatic development followed thereafter by a reciprocal...

...C.R. Vanderburg; E.D. Hay Important and precisely regulated transitions in tissue phenotype from epithelium to mesenchyme and from mesenchyme to epithelium occur in the developing embryo. The gene for E-cadherin has been shown to cause fibroblastic cell lines to become epithelioid in culture. We...

... and the inteφapillar region. On the surface of the branches of the filiform papillae, microridges were rarely seen. On the surface of the fungiform papillae, indistinct microridges were observed. Histologically, the dorsal lingual epithelium revealed three different regions: the epithelium on the anterior side...

Whether this peculiar vascular complex has any specific function needs to be investigated further.The presence of these vessels apparently ‘isolated’ within a leptomeningeal subcompartment may provide a suitable...

In the middle of the posterior end of the lingual body, a single vallate papilla was located. Higher magnification of the lingual dorsal epithelium revealed that prominent microridges and elevated...
