The technology of the cultivation of mesenchymal stem cells with magnetic particles for the subretinal injection was developed in this work. The estimation of the effect of magnetic particles on the proliferation and functional activity of mesenchymal stem cells has been done. We studied the induction of apoptosis and viability of stem cells with magnetic particles. The efficiency of the labeling of MSCs by magnetic particles for this technology is about 90 %, the viability of stem cells is about 95 %.
