From: The anterior esophageal region of Schistosoma japonicum is a secretory organ
TEM of anterior esophagus cell bodies. A, Transverse section of anterior esophageal region, showing greatly extended lining cytoplasm while massive numbers of light vesicles (LV) are present in the elongated cell bodies (CB). B, Higher magnification of the cell bodies with abundant rough endoplasmic reticulum (ER) and Golgi apparatus (G), indicative of light vesicle manufacture. C, Anterior esophagus cell bodies showing light vesicles of variable size and appearance. D, Light vesicles with central dense spheroidal (DS) material. E, Light vesicles with material applied to the outer bounding membrane. F, High magnification of light vesicle reveals that this material is composed of membranous lamellae. Scale bar: A 5 μm; B 500 nm; C 2 μm; D 200 nm; E 500 nm; F 200 nm.
