Tumors have become the primary enemy of human life and health, and their incidence is increasing year by year. At present, there are surgery, radiotherapy, chemotherapy, and immunotherapy for cancer treatment. The serious side effects of radiotherapy and chemotherapy make the patients afraid of medical treatment, which further indirectly cause failure treatment. Although surgery has the possibility of radical treatment in the early stage, while most patients are found in the advanced stage, the conditions are heavy, and the operation is difficult or the lesion cannot be completely removed, eventually leading to metastasis or recurrence. In contrast, the emergence of stem cells transplantation treatment has undoubtedly brought new hope to the treatment of cancer. With the rapid development of molecular biology, stem cell transplantation has become one of the main effective treatments.
