Popis: BACKGROUND: The term 'pinopod' or 'pinopode' has been used indiscriminately since the 1970s to describe most apical structures on uterine epithelial cells and as such suggests a cross species structural functionality. This study looks at the apical cellular protrusions in rats and humans and compares their pinocytotic ability. METHODS: We have utilized standard tracer techniques in an attempt to determine the functionality of the uterine surface protrusions in the human based on results reported in rats. RESULTS: Pinopods in rat tissue demonstrated tracer uptake, but no tracer uptake in the apical protrusions of human uterine epithelium was evident. CONCLUSIONS: These findings indicate that the uterine surface protrusions observed in the human are not pinocytotic and therefore probably perform a function different from similar structures observed in rats and mice. This highlights the need to alter nomenclature from pinopods to uterodomes.
