23 Jul Placenta stem-cell anti-tumor vaccine, preparation method and application thereof
Abstract
The invention relates to a biomedical engineering technology, in particular to anti-tumor vaccine prepared from placenta stem cells, a preparation method and application thereof. In the invention, the vaccine is prepared by saving the placenta stem cells after being cultured for 8 generations in small freezing tubes, and each small freezing tube contains 5*105 (200Mul) placenta stem cells. The preparation method of the vaccine comprises the following steps: (1) treating a placenta tissue; (2) acquiring the placenta stem cells; (3) culturing the placenta stem cells and sub-culturing for 8 times; and (4) preparing the placenta stem-cell anti-tumor vaccine. The invention provides a cell biological preparation which have an effect on vaccine defense before establishing tumors so that an organism generates a specific immune antibody and sensitized lymphocytes on tumor stem cells, and inhibit growth and migration of the tumor stem cells to obtain the cell biological preparation for blockingup generation, development and transfer of the body tumors, wherein, the tumor inhabitation ratio reaches up to 70%; and the placenta stem-cell anti-tumor vaccine can be applied to control various tumors such as lung cancer, breast cancer, colon cancer, melanoma and the like.
