The invention belongs to the technical field of
biology, and particularly discloses a
mesenchymal stem cell composite preparation for treating
neurological function deficiency after brain injury, the active ingredients of the
mesenchymal stem cell composite preparation comprise mesenchymal stem cells and exosomes, the mesenchymal stem cells are
umbilical cord mesenchymal stem cells, and the exosomes are used for treating
neurological function deficiency after brain injury. The
exosome is
umbilical cord mesenchymal stem cells, the dosage of the
umbilical cord mesenchymal stem cells is 1 * 10 < 5 >-2 * 10 < 5 > cells, and the dosage of the
exosome is 200-400 [mu] g. The umbilical cord mesenchymal stem cells and the
exosome are used in a combined mode, the treatment dosage and the combination proportion of the umbilical cord mesenchymal stem cells and the exosome are defined, the synergistic effect of the umbilical cord mesenchymal stem cells and the exosome is exerted, the
survival rate of brain injury cells can be increased, the
secretion level of
inflammatory factors TNF-alpha is reduced, meanwhile, expression of
neurotrophic factors NGF is promoted, and the brain
injury treatment effect is improved. Therefore, the repair and improvement of the
neurological function after the brain injury are realized, the neurological function loss after the brain injury can be more effectively improved, and a new scheme and thought are provided for the
clinical treatment of the neurological function loss after the brain injury.
