The viability of reimplanted MSCs within the clot is assessed using a live/dead assay, with 90% of the cells within the clot being viable (green fluorescence) while only 10% are dead (red fluorescence). The morphology of the clot using scanning electron microscopy shows a scaffold rich in fibrous strands, which are formed from fibrinogen found in the ACP and can be seen entangling platelets, red blood cells, erythrocytes, and MSCs within the clot. (ACP, autologous conditioned plasma; MSCs, mesenchymal stem cells)
