Abstract

The invention discloses a secretion inducing medium for large-scale preparation of human umbilical cord mesenchymal stem cell factors. The secretion inducing medium is mainly prepared by dissolving DMEM (Dulbecco's modified eagle medium), L-alanyl-L-glutamine, 4-2-ethoxyl-1-piperazine ethanesulfonic acid, D-glucose and L-ascorbic acid inside phosphate buffer, wherein the concentrations of the DMEM, the L-alanyl-L-glutamine, the 4-2-ethoxyl-1-piperazine ethanesulfonic acid, the D-glucose and the L-ascorbic acid inside the secretion inducing medium are, respectively, 400-600 ml / L, 1-3 mmol / L, 10-20 mu mol / L and 10-100 mu mol / L. The secretion inducing medium for large-scale preparation of the human umbilical cord mesenchymal stem cell factors is applicable to large-scale cultivation of human umbilical cord mesenchymal stem cells and can efficiency induce secretion of active factors.

Description

technical field [0001] The invention belongs to the field of medium for mesenchymal stem cells, in particular to an induced secretion medium for large-scale preparation of human umbilical cord mesenchymal stem cell factors. Background technique [0002] Mesenchymal stem cells are derived from the mesoderm and ectoderm in the early stages of development and belong to pluripotent stem cells. It has attracted increasing attention because of its multi-directional differentiation potential, hematopoietic support and promotion of stem cell implantation, immune regulation and self-replication. Mesenchymal stem cells were first discovered in the bone marrow, and later found in many kinds of tissues in the process of human development and development. At present, we can isolate and prepare mesenchymal stem cells from bone marrow, fat, umbilical cord, synovium, bone and other tissues, among which the bone marrow-derived mesenchymal stem cells were studied the earliest. However, bone...
