The effect of age on proliferating cell nuclear antigen expression in oral gingival epithelium of healthy and inflamed human gingiva.

Abstract

BACKGROUND Age-related changes in proliferative activity in human gingival epithelium are uncertain. Proliferating cell nuclear antigen (PCNA) is a nuclear protein associated with the cell cycle. Nuclear PCNA immunoreactivity is found in the proliferative compartment of normal tissues. The aims of this study were to investigate the localization of PCNA… (More)
