Abstract

The invention discloses a medium for umbilical cord MSCs (mesenchymal stem cells). The medium is prepared from the following components: a basal medium, human serum albumin, myricetin, panax notoginsenoside, emodin, linoleic acid, trypsin, aprotinin, lumican, basic fibroblast growth factors, folic acid, beta-mercaptoethanol, astragalus polysaccharides, transferrin, vitamins and amino acid. The medium is compounded from the basal medium, human serum albumin, myricetin, panax notoginsenoside, emodin, linoleic acid, trypsin, aprotinin, photoprotective glycoprotein, the basic fibroblast growth factors, folic acid, beta-mercaptoethanol, astragalus polysaccharides, transferrin, the vitamins and the amino acid, the components play a synergistic role, and accordingly, the umbilical cord MSCs can be successfully cultured, proliferation of the umbilical cord MSCs is promoted, the growth rate of the umbilical cord MSCs is increased, activity of the umbilical cord MSCs during in-vitro proliferation and differentiation is improved, and the apoptosis rate is decreased.

Description

technical field [0001] The invention belongs to the field of biotechnology, in particular to a culture medium for umbilical cord mesenchymal stem cells. Background technique [0002] Umbilical cord mesenchymal stem cells (Mesenchymal Stem Cells, MSCs) refer to a kind of multifunctional stem cells existing in the umbilical cord tissue of newborns, which can differentiate into many kinds of tissue cells and have broad clinical application prospects. [0003] Umbilical cord mesenchymal stem cells have high differentiation potential and can differentiate in multiple directions. It has broad clinical application prospects in tissue engineering of bone, cartilage, muscle, tendon, ligament, nerve, liver, endothelium and cardiac muscle. It has been reported that mesenchymal stem cells were isolated from human umbilical cord, and the cell content and proliferation ability were superior to those of bone marrow mesenchymal stem cells, the immunogenicity was lower than that of bone mar...
