Nature’s ingenious systems: A layer of cells called endothelial cells lines the interior of blood vessels. When blood flows through the vessels, such cells only divide to replace dead cells. However, if there is a blood clot preventing blood from flowing across the endothelial cells, they begin to divide more actively. New research from the Niels Bohr Institute demonstrates that cell division is very ordered. The new cells move away from each other and create a dynamic movement with eddies in a large area. This presumably helps to widen the vessel around the blockage. The results are published in the prestigious journal Nature Communications.
A cell division in a blood vessel creates a controlled and far-reaching organization of the tissue, which may contribute to healing around blood clots. In the image, a cell is dividing across the middle and the red areas show an eddy rotating clockwise and the purple areas show an eddy rotating counter-clockwise.
