False-colour SEM of a macrophage & lymphocyte
Macrophage in contact with a lymphocyte. False- colour scanning electron micrograph (SEM) of a macrophage (gold) in contact with a lymphocyte, a type of white blood cell. The macrophages irregular shape is characterised by thin projections (filopodia), used for support & motility. Macrophages form part of the bodys reticulo-endothelial (or macrophage-monocyte system), which includes those cells & tissues with phagocytic (digestive-like) properties. Macrophages engulf & digest cellular debris, bacteria, other foreign bodies & aged red cells. Magnification unknown

EDITORS COMMENTS
This print showcases a false-colour scanning electron micrograph (SEM) of a macrophage and lymphocyte in close contact. The macrophage, depicted in gold, exhibits an irregular shape characterized by thin projections known as filopodia, which serve the purposes of support and motility. As part of the body's reticulo-endothelial system or macrophage-monocyte system, these remarkable cells possess phagocytic properties. Macrophages play a vital role in our immune defense mechanism. They are responsible for engulfing and digesting cellular debris, bacteria, foreign bodies, and even aged red blood cells. This SEM image offers us a glimpse into their intricate structure and function at an unknown magnification. The lymphocyte seen here is one type of white blood cell that interacts with the macrophage. Together, they form an integral part of our body's immune response against pathogens and other harmful substances. This visually stunning photograph not only highlights the beauty found within our own bodies but also serves as a reminder of the complexity and efficiency of our defense systems. It provides valuable insights into human biology while bridging the gap between science and art through its false-colour representation.
