On closer inspection you can see the metaplastic squamous cells are distinguishable from the regular squamous cells of the cervix due to their darker staining cytoplasm and their lack of honeycomb appearance.https://histologyblog.com/wp-content/uploads/2013/01/faces-of-cervix-6.pngChanging facesThe transformation zone becomes hardly visible on the ectocervix. The original SCJ returns close to where it was premenarche.https://histologyblog.com/wp-content/uploads/2013/01/faces-of-cervix-5.pngChanging facesThe transformation zone begins to migrate into the endocervical canal. Both SCJs also migrate in this direction.https://histologyblog.com/wp-content/uploads/2013/01/faces-of-cervix-4.pngChanging facesDue to a process known as "squamous metaplasia", the site of the ectropian has now become completely replaced with new types of squamous cells (purple). The point where the transformation zone meets the columnar cells (at the external os) forms the new SCJ. Now there are two types of SCJs.https://histologyblog.com/wp-content/uploads/2013/01/faces-of-cervix-3.pngChanging facesAt this age, the columnar epithelium become exposed onto the ectocervix. The ectropian does not always occur symmetrically. The SCJ now lies on the ectocervix, rendering very few squamous cells on the cervix (now, they are mostly found on the vaginal wall).https://histologyblog.com/wp-content/uploads/2013/01/faces-of-cervix-2.pngChanging facesColumnar cells (blue) are within the endocervix, while the ectocervix and vagina are completely lined with squamous epithelium (yellow).
