Blood Clot Formation: Trapped Red Blood Cells (Erythrocytes) in Fibrin. I think this is really striking

Kupffer cells are cells of the immune system that patrol the liver to recycle old red blood cells and degrade pathogens. Here, Kupffer cells are moving within small blood vessels lined with holes that allow the cells to enter the liver at sites of damage or inflammation.    Image by Tom Deernick.

"The Lone Ranger"- Kupffer cell (specialized macrophage, green) patrolling the tiny vessels in the liver called sinusoids, where they recycle old red blood cells and ingest pathogens.

Blood clot. Coloured scanning electron micrograph (SEM) of a blood clot from the inner wall of the left ventricle of a human heart. Red blood cells (erythrocytes) are trapped within a fibrin protein mesh (cream). The fibrin mesh is formed in response to chemicals secreted by platelets (pink), fragments of white blood cells. Clots are formed in response to cardiovascular disease or injuries to blood vessels. Connective tissue (orange) is also seen.
