Context: In a recent discovery published in Nature, scientists found that haemoglobin, typically associated with red blood cells, is also produced by chondrocytes, the cells responsible for making cartilage in the body.
What is haemoglobin?
Haemoglobin is a Iron containing protein found in red blood cells that carries oxygen from the lungs to the body’s tissues and returns carbon dioxide to the lungs for exhalation. It plays a crucial role in oxygen transport and maintaining the body’s overall oxygen balance.
What does the new study says?
A recent study revealed that chondrocytes, responsible for forming cartilage, produce haemoglobin, contrary to the previous belief that only Red Blood Cells (RBCs) contained it.
Chondrocytes play a role in strengthening and flexibilizing cartilage, and they rely on haemoglobin for oxygen transport and survival. Haemoglobin within chondrocytes stores and releases oxygen as needed.
What are Cartilage?
Cartilage is a flexible and connective tissue found in various parts of the body, such as joints, the nose, and ears. It provides support and cushioning while allowing for smooth movement in the joints.
