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

Embodiment Construction

[0014] 1. Experimental materials

[0015] Amniotic fluid from healthy pregnant women in the second trimester was selected, signed informed consent, and agreed to be used in scientific research experiments.

[0016] The special medium for human amniotic fluid mesenchymal stem cells was purchased from BI Company; fetal bovine serum was purchased from Thermo Company of the United States; DMEM medium was purchased from Gibco Company of the United States; The culture medium was purchased from Shanghai Raas Blood Products Co., Ltd.; the stem cell osteogenic differentiation medium was purchased from PromoCell; the neural differentiation medium: 20 μg / L epidermal growth factor and 20 μg / L were added to the DMEM / F12 medium containing 2% B27 Formulated with Basic Fibroblast Growth Factor of L.

[0017] 2. Experimental method

[0018] 1. Isolation and culture of human amniotic fluid mesenchymal stem cells (hAFSCs)

[0019] Dilute the amniotic fluid with PBS containing EDTA at a ratio ...

Abstract

The invention relates to a transport liquid for human amniotic fluid mesenchymal stem cells. The present invention adds 5 μ M heterophylla cyclic peptide A on the basis of the existing technology, which can effectively overcome the obvious deficiency of the cell viability reduction after being suspended for 72 hours in the prior art transport liquid. The formula of the transport liquid of the present invention is: by mass percentage 0.2% trehalose solution (PBS solution of trehalose), 25% red blood cell storage solution, 5% 0.2% heparin calcium solution (heparin calcium PBS solution) and 40% human albumin injection are mixed uniformly at room temperature. And contain 5μM heterophyllin A. The transport solution can not only improve the viability of human amniotic fluid mesenchymal stem cells transported for 72 hours, but also not affect their multidirectional differentiation ability.

Description

technical field [0001] The invention relates to the field of stem cells, in particular to a transport solution for human amniotic fluid 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 di...
