Problems solved by technology

Normal saline is a commonly used infusion medium, which is convenient and safe in clinical application, but the activity of cells in normal saline decreases very quickly, and the loss of cell activity can reach as much as 30% within 10 hours, so it is only suitable for short-term storage of cells , immediate infusion
Plasma can maintain cell activity well, but plasma contains a large number of unknown components, allogeneic infusion has potential safety hazards, and homologous infusion is extremely costly

Abstract

The invention discloses a cell preserving liquid. The cell preserving liquid contains 120-137mM of NaCl, 2.2-2.8mM of KCl, 3-9mM of sodium citrate, 15-20mM of glucose, 0.6-1.2mM of CaCl2, 1.5-3.5%(w / v) of alhumin, 0.3-0.8%(w / v) of amino acids and 0.015-0.035%(w / v) of vitamins. The invention also discloses a preparation method of the cell preserving liquid, and a cell preserving method. The cell preserving liquid is safe, can maintain the motility rate of cells for a long time, has a low cost, and has a good application prospect and a good economic benefit.

Description

technical field [0001] The invention relates to a cell preservation solution. Background technique [0002] Cell, the most basic unit of life, has application value in many aspects. Stem cells (SC) are a kind of pluripotent cells with self-renewing ability, which can differentiate into various functional cells under certain conditions. Stem cells are not fully differentiated and immature cells, which have the potential to regenerate various tissues and organs and the human body. They are called "universal cells" in the medical field. Mesenchymal stem cells (mesenchymal stem cells, MSC) are important members of the stem cell family, derived from the mesoderm and ectoderm in the early stages of development. Originally found in bone marrow, MSCs have attracted increasing attention because of their multi-lineage differentiation potential, hematopoietic support and promotion of stem cell implantation, immune regulation and self-replication. Under specific induction conditions ...
