4.1.1 POJA-L4051+4052+4053
Title: Paneth cell in the jejunum (human, rat).
Description: (A) Stain: Hematoxylin-eosin, human. (B, C) Electron micrographs, rat.
Paneth cells usually are located at the bottom of the crypts in the jejunum, surrounded by the common resorptive enterocytes (2).
The Paneth cells produce and secrete large refractive granules that contain several types of defensins, substances with anti-microbial effects. The cells do not bear microvilli contrasting with the enterocytes (B). The cells have a well-developed RER (rough endoplasmic reticulum) appropriate for the synthesis of the mentioned proteins.
In (C, 3) a lymphocyte in diapedesis is present.
Keywords/Mesh: Paneth cell, jejunum, enterocytes, defensins, electron microscopy, histology, POJA collection
