Abstract

The invention relates to a kit for separating human umbilical cord blood stem cells and its using method. The kit is composed of a solution A, a solution B and a solution C, wherein, the solution A is added with appropriate amounts of puerarin and 4-hydroxycinnamic acid phenethyl ester. The invention also relates to a human umbilical cord blood stem cell treatment liquid, which contains the human umbilical cord blood stem cells prepared by the kit of the invention. The kit provided in the invention can rapidly and efficiently separate stem cells from umbilical cord blood, and is in favor of popularizing stem cell treatment technologies.

Description

technical field [0001] The invention relates to a kit for isolating human umbilical cord blood stem cells and a using method thereof. The present invention also relates to a treatment liquid for human umbilical cord blood stem cells, which comprises human umbilical cord blood stem cells prepared by using the kit of the present invention. Background technique [0002] Stem cells are primitive cells with the potential of self-replication and multi-directional differentiation. They are the origin cells of the body and the primitive cells that form various tissues and organs of the human body. Under certain conditions, it can differentiate into a variety of functional cells or tissues and organs, which are called "universal cells" in the medical field. [0003] Stem cells are especially important for early human development, and multipotent stem cells are also found in children and adults. Take for example one of the stem cells we are most familiar with, hematopoietic stem cel...
