Fenestrated capillaries
Fenestrated capillaries are present in locations, such as endocrine tissues, digestive system, and renal glomeruli, to facilitate transport through the capillary wall. On the left is a light micrograph of endocrine cells of the anterior pituitary gland. The electron micrograph on the right shows a pituitary cell adjacent to a fenestrated capillary. Fenestrations are only visible with the electron microscope. 1000x (left), 10,000x (right)
