Figure 1.

Heterogeneous feature of stroke emboli. At least two serial sections of thrombi retrieved from ischaemic stroke patients were stained with Martius scarlet blue to identify different component of thrombus. (A–C) Representative microphotographs taken with lower magnification from three different patients’ thrombi, showing the thrombus tissue consists of different component which is stained with different colour (yellow, pinkish, red and blue). (D–F) Microphotographs taken with higher magnification from the rectangular area in (A–C), showing red blood cells (yellow), fibrin strands (red/ intense pink), platelets (pinkish) and white blood cells (blue) all are present.
