We studied proliferative activity of multipotent mesenchymal stromal cells on collagen matrices containing platelets stabilized with silver nanoparticles. Dose-dependent stimulation of the growth of stromal cells without their structural damage was observed in the presence of stabilized platelets in proportion of 20-120 mln per 105 multipotent mesenchymal stromal cells. The same doses of non-stabilized platelets produced less pronounced stimulation effect. In higher doses (≥180 mln) stabilized platelets inhibited cell proliferation and induced their damage. Stabilized platelets enhanced migration of multipotent mesenchymal stromal cells; after formation of the monolayer, they actively colonized deep layer of the collagen matrix. The formed monolayer of multipotent mesenchymal stromal cells survived over 14 days without appreciable cell damage.
