=Distribution of epithelial cords and primary follicles in the ovarian cortex

Panoramic view composed of nine images shows ovarian tunica albuginea filled with CK18+ mesenchymal cells, upper cortex (uc) with epithelial channels (black arrowhead), cords (dashed and white arrowheads – see right inset) and follicle-like structures (solid box, see upper left inset for details). Lower cortex (Ic) shows isolated (dashed box – see lower left inset) and grouped primary follicles (dotted box). Bars in insets indicate μm. Cytokeratin 18 immunostaining, hematoxylin counterstain.

This figure shows formation of epithelial channels (arrowhead), longitudinally (dashed arrowhead) and perpendicularly viewed solid epithelial cords (white arrowheads and right inset), and follicle like structures containing stromal elements (solid box, see left top inset for detail) in the upper cortex (uc). These structures were arranged in a surprisingly straight row (see also Fig. 1D). In some ovaries a similar orientation of primary follicles was observed in the lower ovarian cortex (Ic).
