Problems solved by technology

However, the number of viable cells of the three types of cells (human amniotic fluid, umbilical cord, and placenta-derived mesenchymal stem cells) decreased significantly after being placed in the cell transport solution at room temperature for 72 hours, which is not suitable for long-distance transport

Abstract

The invention relates to a transporting fluid for human umbilical cord mesenchymal stem cells. According to the invention, heterophyllin B with a concentration of 5 [mu]M is added on the basis of theprior art, so the shortcoming that conventional transporting fluids is obviously reduced in cell viability after suspension for 72 h can be effectively overcome. The transporting fluid of the invention is prepared by uniformly mixing, by mass, 30% of a trehalose solution (a PBS solution of trehalose) with a concentration of 0.2%, 25% of a red blood cell storage solution, 5% of a heparin calcium solution (a PBS solution of heparin calcium) with a concentration of 0.2% and 40% of human albumin injection at room temperature, and further comprises heterophyllin B with a concentration of 5 [mu]M. The transporting fluid of the invention can improve the survival rate of human umbilical cord mesenchymal stem cells having been transported for 72 hours, and does not affect the multi-directional differentiation ability of the human umbilical cord mesenchymal stem cells.

Description

technical field [0001] The invention relates to the field of stem cells, in particular to a transport liquid for human umbilical cord mesenchymal stem cells. Background technique [0002] Stem cells are a class of cells with self-renewal and multilineage differentiation capabilities. It is because of its regenerative potential and plasticity that it is widely used in regenerative medicine and stem cell research. Stem cells offer hope for many diseases that currently lack effective treatments, including stroke, Huntington's disease, Alzheimer's disease and Parkinson's disease. [0003] Mesenchymal stem cells are multipotent stromal cells isolated from adult and fetal tissues, defined as adherent fibroblast-like cells. Mesenchymal stem cells have intrinsic homing ability, can migrate to damaged tissues, and actively participate in tissue repair. Although mesenchymal stem cells are pluripotent, their self-renewal ability gradually decreases leading to stagnation of cell divi...
