Clot Formation Can Be Filmed
Blood clot formation

Russian scientists developed a unique diagnostic device for blood-coagulation system. The innovation allows direct observations of how fast do clots appear in blood and measure their formation speed.
      
      Researchers put tiny blood samples into a transparent cuvette, one of which walls is covered with a special nano-coating similar to cell membrane. This coating contains a protein, launching a number of processes, which in organism result in formation of a dense fibrinous clot, a so-called patch of vessel wall.
      
      Molecules of this protein are found in almost every cell of our organism except blood cells and endothelium, a natural cover of our tissues. When endothelium is damaged, the protein uncovers and forms a patch. The same clot forms in a cuvette with patients blood.
      
      The growth of a fibrinous clot is registered by means of digital camera, and series of such images can become a film about clot formation.
