4.1.1 POJA-L4043+4044+4045+4046
Title: Resorptive epithelium of the jejunum (dog, rabbit, gerbil)
Description: Stain: (A) Hematoxylin-eosin. (B, C, D) Electron micrographs.
(A): The epithelium (2) with columnar cells at the villus has an epithelium with the task to resorb the digested food. Their surface is amplified by microvilli, the so called brush border (2). The lamina propria area below the epithelial lining is well capillarized (3).
(B, C, D) The brush border comprises a broad array of microvilli on top covered with a glycocalix of mucopolysaccharides (D). Numerous electron dense resorption vesicles (arrows, ↘↘) are present as pinched off vesicles from the microvilli processes. The lateral intercellular space (4) between the epithelial cells often is enlarged illustrating the (water) transport from the cells to the underlying capillaries.
Keywords/Mesh: jejunum, brush border, transport vesicles, electron microscopy, epithelium, histology, POJA collection
