Immunity in the Cervix: Interphase between Immune and Cervical Epithelial Cells

Figure 2

Microscopic illustration of the cervix. The cervix is divided into the two main compartments, namely, the microbe-laden ectocervix and “sterile” endocervix, which are bordered by the cervical transformation zone (CTZ) and their associated immune cells. The ectocervix (and vagina, not shown) has squamous stratified epithelia, while endocervix (and uterus, not shown) has simple columnar epithelia.
