Abstract:
The stratified squamous epithelium lining the mouse anal canal revealed various stages of keratinization. Considering the ultrastructural features, it is suggested that the epithelium lining the distal part shows more advanced keratinization than in the proximal part. Further, the width of the microridges in the distal part was about doubled compared to that in the proximal part. The difference in the width of microridges appears to be an important marker of the degree of keratinization.
