Abstract

The invention discloses application of vitamin C in promoting umbilical cord mesenchymal stem cell proliferation without influencing stem cell activity, viability, differentiation and senescence, andapplication of vitamin C in preparing a culture medium for promoting umbilical cord mesenchymal stem cell proliferation without influencing stem cell activity, viability, differentiation and senescence. A phenomenon is found that after a current stem cell culture medium is adopted to achieve stem cell adherence, AA is added (without other complex components being added), and then proliferation ofstem cells can be promoted. Through data, a result is proven that although AA can significantly increase the quantity of the stem cells within a short period of time, the activity, viability and cellcycle of the stem cells are not different from those of stem cells cultured in a control culture medium without AA. Therefore, a fact is illustrated that AA supplementation can simply promote cell proliferation, not reduce the activity and viability of the stem cells, and not promote stem cell senescence.

Description

technical field [0001] The invention relates to the application of vitamin C in promoting the proliferation of umbilical cord mesenchymal stem cells without affecting the activity, viability and differentiation aging of stem cells. and a culture medium containing vitamin C for promoting proliferation of umbilical cord mesenchymal stem cells, belonging to the technical field of cell culture. Background technique [0002] At present, stem cells, as a new treatment method, are being widely used in clinical trials of various diseases, and the vast majority of clinical trials have proved that stem cells can better improve symptoms. However, in the future clinical application of stem cells, it is necessary to solve how to proliferate to the number of cells that meet the use requirements in a shorter period of time, while ensuring that the mesenchymal stem cells still maintain good cell activity after large-scale expansion, and the number of proliferated cells remains high. Potent...
