We studied the growth-stimulating effect of platelet-based preparations obtained by different methods on cultured human fibroblasts M-22. Platelet lysates prepared from platelet-rich plasma, platelet-poor plasma, concentrated suspension of platelets washed from plasma, and platelet-rich plasma activated with calcium chloride (ActPRP) were used. The volume of the platelet preparations was 10-500 μl per 104 cells. The most effective dose of platelet-rich and platelet-poor plasma in cell culture was 20 μl, whereas for ActPRP, the most effective dose was 500 μl. Lysates of platelet-rich and platelet-poor plasma in doses of 100-500 μl inhibited fibroblast growth and disturbed their structural integrity. At the same time, lysates of washed platelets in doses of 10-500 μl stimulated cell growth and preserved their viability. An inverse correlation was found between the number of cells in culture and the level of proinflammatory cytokines in the platelet preparations.
