Islet of Langerhans beta cell, TEM
Islet of Langerhans beta cell. Transmission electron micrograph (TEM) of a section through a beta cell in an islet of Langerhans in the pancreas. Beta cells secrete the hormone insulin, which is stored in many cytoplasmic granules (black spots) and released into blood vessels to regulate the supply of glucose throughout the body. Magnification: x20, 000, when printed 10 centimetres tall

EDITORS COMMENTS
This print showcases the intricate beauty of an Islet of Langerhans beta cell, captured using a Transmission Electron Microscope (TEM). The image reveals a section through the pancreas, specifically focusing on a beta cell responsible for secreting insulin. At a magnification of x20,000, this detailed snapshot unveils the inner workings of the cell. Numerous cytoplasmic granules can be observed throughout the beta cell, appearing as striking black spots against the monochrome background. These granules store and release insulin into nearby blood vessels to regulate glucose levels in our body. The photograph not only highlights the structural complexity of this biological marvel but also emphasizes its vital role within our endocrine system. As one component of the Islet of Langerhans - clusters of cells scattered throughout the pancreas - these beta cells play a crucial part in maintaining proper hormonal balance. With its high level of detail and clarity, this TEM image serves as an invaluable resource for researchers studying cellular biology and histology. It offers insights into organelles involved in secretion processes while providing an awe-inspiring glimpse into nature's microscopic wonders. Science Photo Library has once again delivered an exceptional visual representation that bridges artistry with scientific exploration.
