Insulin-secreting pancreatic cells

Insulin production. Artwork of a section through beta cells secreting insulin (blue spheres) into a capillary (small blood vessel, grey tube). Beta cells are found in the pancreas. Energy-producing structures (mitochondria, green) are seen within the cells, as well as the folded membrane (upper centre), called the endoplasmic reticulum, where such proteins can be synthesised and stored. The insulin in the cell is contained within secretory granules (pink, round). These migrate through the cell to release their insulin cargo into the bloodstream. Insulin is a hormone that controls blood sugar level by promoting glucose storage in the liver and muscles

EDITORS COMMENTS
This print showcases the intricate world of insulin-secreting pancreatic cells. The artwork provides a detailed section through beta cells, which are responsible for producing and secreting insulin into the bloodstream. The blue spheres represent the insulin molecules being released into a capillary, depicted as a small grey tube. Within these beta cells, we can observe energy-producing structures known as mitochondria, highlighted in green. These powerhouses play a crucial role in generating energy for cellular functions. Additionally, the folded membrane seen in the upper center is called the endoplasmic reticulum - an essential site where proteins involved in insulin synthesis and storage are produced. The pink round granules within the cell contain stored insulin and migrate throughout to release their precious cargo into circulation when needed. Insulin acts as a vital hormone that regulates blood sugar levels by facilitating glucose storage in both liver and muscle tissues. This stunning illustration beautifully combines elements of anatomy, chemistry, physiology, and cytology to provide an insightful visual representation of this complex biochemical process occurring within our own bodies. It serves as a reminder of how intricately designed our human body is at even its smallest scale – highlighting the remarkable interplay between different components necessary for maintaining proper hormonal balance and blood sugar control.
