Abstract

The invention discloses a preparation method for anti-aging cell preparation. The preparation method includes the following steps: adding the extracted bone marrow into a culture fluid, centrifuging and discarding the supernatant and inoculating the culture medium in a culture dish; replacing the liquid for the first time after 24-48 hours of primary culture, then replacing the liquid every 3d, sub-culturing at the ratio of 1:2 in 12-18h after the third times of replacement, adding the third generation of cultured mesenchymal stem cells to the normal saline for resuspending, and preparing the bone marrow mesenchymal stem cell preparation. By separating and culturing the bone marrow mesenchymal stem cells, and adding the bone marrow mesenchymal stem cells cultured in vitro to the normal saline, the bone marrow mesenchymal stem cell preparation can be obtained; The result shows that the cell preparation can improve the damage of cell morphology of the aged rat, reverse aging damage to some extent, and provide clues for studying the anti-aging mechanism of the bone marrow mesenchymal stem cells, as well as human anti-aging.

Description

technical field [0001] The invention belongs to the technical field of cell preparations, in particular to a preparation method for anti-aging cell preparations. Background technique [0002] China is rapidly entering an aging society. At present, there are about 100 million Chinese people over the age of 10. It is estimated that in 2050, the elderly over 60 years old will account for 30% of the population in China, and the various troubles and problems brought about by aging will become more serious. Aging and death are unavoidable final outcomes for individuals of any species, but so far our understanding of the mechanism of aging is still quite limited. Given its importance, aging has always been a hot topic in biological research. [0003] Bone marrow mesenchymal stem cells are a type of pluripotent stem cells derived from the mesoderm in early embryonic development, and are stem cells of the connective tissue throughout the body. A large number of experiments have co...
