The invention discloses a
stem cell preparation for treating
ischemic cardiomyopathy and a preparation method of the
stem cell preparation. The preparation consists of mesenchymal stem cells, cardiac stem cells and vascular endothelial stem cells, and a
solvent is
platelet-rich
plasma lysate of a patient. The stem cells express a corresponding specific identifier and do not express a corresponding non-specific identifier at the same time. The preparation method comprises the following steps: (1), preparing mesenchymal stem cells between a
placenta and an
umbilical cord; (2), applying different induction culture systems to induce the mesenchymal stem cells in the step (1) to be cardiac stem cells and vascular endothelial stem cells; (3), preparing the
solvent which is the
platelet-rich
plasma lysate; and (4), uniformly mixing and preparing the
stem cell preparation. The stem
cell preparation disclosed by the invention is rich in resource, easy to prepare, convenient to collect, and free of pain while being applied; moreover, the stem
cell preparation is low in immunological rejection after being transplanted. The stem
cell preparation comprises a plurality of stem cells, so that advantages of combined effect of a plurality of cells can be brought into play; the
solvent is easily available, and can directly act on a patient; besides,
transplantation effect is enhanced.
