Problems solved by technology

[0002] In recent years, the cell culture medium used in the process of culturing and expanding bone marrow mesenchymal stem cells generally needs to add fetal calf serum, and some also add some other cell growth factors to maintain the culture and expansion of cells. When fetal bovine serum is added to the cell culture medium, the fetal bovine serum will contain foreign proteins, and may carry bacteria, viruses, protein infectious diseases or prions into the cells, which will not be conducive to clinical treatment application

Embodiment 1

[0024] A cell culture medium conducive to the in vitro culture and expansion of autologous bone marrow mesenchymal stem cells:

[0025] The complete medium used for primary cell culture has a final concentration as follows: PL platelet lysate 5-20%, heparin 2-5U / ml, doxycycline 5-10 μg / ml, solvent as basal medium, The basic medium is DMEM medium;

[0026] The complete medium used for cell culture in the first generation and after the first generation has a final concentration as follows: PL platelet lysate 5-20%, heparin 2-5U / ml, doxycycline 5-10 μg / ml, The solvent is the basal medium, and the basal medium is AMEM culture fluid.

[0027] The percentage of PL in the complete medium of cells is added according to the age of the person, the percentage of PL added is 5-10% for those less than or equal to 45 years old, and the percentage of PL added for those older than 45 years is 10-20%.

Abstract

The invention relates to the technical field of cell culture media, and discloses a cell culture medium beneficial to in-vitro culture of autologous bone marrow mesenchymal stem cells. The cell culture medium is characterized in that an autologous PL blood platelet lysis buffer is added during preparation. The autologous bone marrow mesenchymal stem cells are cultured by using the cell culture medium added with the PL blood platelet lysis buffer so as to ensure that the cell proliferation capability of cells in in-vitro culture; and meanwhile, a phenomenon that the mesenchymal stem cells cannot be affected by exogenous pollution in in-vitro culture and amplification can be ensured, the immunological rejection of allogeneic cells generated in a disease treatment process can also be avoided, and an application of treating self-diseases by using autologous cells clinically can be facilitated.

Description

technical field [0001] The invention relates to the technical field of cell culture medium, in particular to a kind of cell culture medium which is beneficial to the in vitro culture and expansion of autologous bone marrow mesenchymal stem cells. Add the cell culture medium of autologous PL platelet lysate to the cell culture medium. Background technique [0002] In recent years, the cell culture medium used in the process of culturing and expanding bone marrow mesenchymal stem cells generally needs to add fetal calf serum, and some also add some other cell growth factors to maintain the culture and expansion of cells. When fetal bovine serum is added to the cell culture medium, the fetal bovine serum will contain foreign proteins, and may carry bacteria, viruses, protein infectious diseases or prions into the cells, which will not be conducive to clinical treatment application. The present invention uses autologous PL platelet lysate to replace fetal bovine serum and some...
