Problems solved by technology

But, all there is following shortcoming in the developed serum-free mesenchymal stem cell culture medium: 1) complex composition
There are as many as ten or more types of ingredients, resulting in poor stability between batches of culture media and difficulties in quality control; 2) the immune regulation function of mesenchymal stem cells cannot be well maintained
The ability of the cultured mesenchymal stem cells to secrete the immunoregulatory factor PGE2 and inhibit the proliferation of PBMC cells is weak; 3) the multidirectional differentiation potential of mesenchymal stem cells cannot be well maintained
The directed differentiation of cultured mesenchymal stem cells into osteoblasts, chondrocytes, and adipocytes is low
These problems largely limit the industrial transformation and clinical application of mesenchymal stem cells

Abstract

The invention discloses a mesenchymal stem cell culture medium without serum and xenogeneic components and application thereof. The present invention firstly discloses a mesenchymal stem cell culture medium, comprising a basal medium and an additive, the basal medium is a DMEM / F12 medium, and the additive is a human platelet lysate and / or human lipocalin 2. The invention further discloses the application of the mesenchymal stem cell culture medium in culturing mesenchymal stem cells. The mesenchymal stem cell medium provided by the present invention has no serum and no heterologous components, which ensures the safety of clinical application; the components are simple, the stability between batches is good, and the cell expansion ability in vitro is strong, which meets the requirements of industrial transformation; The immunoregulatory ability and multi-directional differentiation ability of mesenchymal stem cells are well maintained to ensure their effective function in clinical treatment.

Description

technical field [0001] The invention relates to the technical field of cell culture. More specifically, it relates to a serum-free, xenogeneous component-free medium for mesenchymal stem cells and its application. Background technique [0002] Mesenchymal stem cells are a type of adult stem cells with self-replication, renewal and multi-lineage differentiation potential, which widely exist in fetal and adult tissues. In addition to self-renewal, mesenchymal stem cells have unique immune regulation and tissue regeneration functions. On the one hand, mesenchymal stem cells regulate immune cells through the interaction with immune cells and paracrine soluble factors, mediate the balance of immune responses, and help the body form a microenvironment that is conducive to the repair or regeneration of damaged tissue cells. The immune regulation of mesenchymal stem cells includes inhibiting the activation of T lymphocytes, reducing the activation and proliferation of B cells and ...
