The invention discloses a human placenta-derived endothelial progenitor cell and a combined drug thereof as well as application of the human placenta-derived endothelial progenitor cell in preparation of a drug for treating radiation-induced thymus injury, and discloses a novel cell treatment drug for reconstructing a thymus microenvironment, recovering T cell generation and promoting thymus function repair and immune reconstruction aiming at thymus radiation injury. The placenta-derived endothelial progenitor cells are found to have an excellent effect of treating the radiation thymus injury, and the human placenta-derived endothelial progenitor cells and the human umbilical cord mesenchymal stem cells are synergistically combined to have a synergistic effect on treating the radiation thymus injury.

This invention provides exosomes derived from rice, their preparation method, and applications. The exosomes have a bilayered membrane spherical structure with a particle size ranging from 20 to 1000 nm. These exosomes are obtained from rice callus tissue and possess high biocompatibility, stability, and sustainable mass production characteristics. Furthermore, experiments have demonstrated that these exosomes have anti-aging, cell regeneration and tissue repair promotion, and protective functions, and can also significantly improve cell absorption efficiency and the delivery efficiency of active ingredients such as peptides.
