Pancreatic exocrine cells, TEM
Pancreatic exocrine cells. Transmission electron micrograph (TEM) of a section through exocrine cells in the pancreas, showing numerous zymogen granules (circles), rough endoplasmic reticulum (ER, dark lines), and Golgi complexes (stacks of ER). These cells synthesize and secrete digestive enzymes into the small intestine. The enzymes are packaged into the zymogen granules in the cells cytoplasm, where they are stored until needed. The cell clusters are called acini. Magnification x6, 000 when printed 10 centimetres wide

EDITORS COMMENTS
This print showcases the intricate structure of pancreatic exocrine cells, captured through a transmission electron microscope (TEM). The image reveals a section of these specialized cells found in the pancreas, which play a crucial role in digestion. The TEM image highlights numerous zymogen granules, represented as circular structures within the cell's cytoplasm. These granules serve as storage units for digestive enzymes that are synthesized and secreted by the exocrine cells into the small intestine. Surrounding these granules are dark lines indicating rough endoplasmic reticulum (ER), responsible for protein synthesis, and stacks of ER known as Golgi complexes. The clustered arrangement of these exocrine cells is referred to as acini, forming an essential part of the pancreas' functionality. With a magnification level of x6,000 when printed at 10 centimeters wide, this photograph offers an up-close view into the complex world of cellular biology. Through this stunning visual representation, we gain insight into how pancreatic exocrine cells contribute to our digestive system's efficiency. This image serves as a testament to both scientific discovery and artistic beauty intertwined within microscopic realms.
