Annotation rationales
Ectocervical granular cells are late-differentiating cells of the stratified squamous ectocervix. Involucrin, transglutaminase and squamous keratins indicate maturation toward a reinforced superficial layer.
Functional implications
They build a mechanically resilient cervical barrier and undergo orderly terminal differentiation before surface shedding.
