Mesenchymal stem cell preparation for resisting Alzheimer's disease and preparation method thereof

The invention provides a mesenchymal stem cell preparation for resisting Alzheimer's disease and a preparation method thereof, and belongs to the technical field of medicines. Adding the subcultured human umbilical cord blood mesenchymal stem cells into a preserving fluid to obtain a stem cell preserving fluid; the preparation method comprises the following steps: extracting grape extract from grape skin, fermenting to obtain grape fermentation liquor, merging, carrying out molecular distillation to obtain grape flavonol substances, embedding the grape flavonol substances, progesterone, pregnenolone and octacosanol in lactide-polyethylene glycol polymer microspheres, adding stem cell preservation liquid, and carrying out freeze-drying to obtain the stem cell culture medium. The prepared mesenchymal stem cell preparation for resisting the Alzheimer's disease can protect the structural integrity and functions of umbilical cord blood mesenchymal stem cells, promote the growth and passage of the umbilical cord bl
