Description

Medical stem cell storage jar

Technical Field

The utility model relates to the technical field of medical appliances, concretely relates to medical stem cell storage jar.

Background

Stem Cells (SC) are a type of pluripotent cells with self-renewal (self-rejuvenating) ability, which under certain conditions can differentiate into a variety of APSC pluripotent cells, and are a type of primitive cells with self-replicating and multipotent differentiation potential, i.e., Stem cells that remain unoriented and have the ability to proliferate, and under appropriate conditions or given appropriate signals, can differentiate into a variety of functional cells or tissue organs, which are also known in the medical community as "universal cells" and are also known in the colloquial and fictional manner as "cells that do what. Stem cells are derived from embryonic, fetal, and adult tissues. Embryonic stem cells from embryonic and fetal tissues have the property of multipotent differentiation into almost all over 200 mature cell types in mature individuals. Adult stem cells (adult stem cells) derived from adult tissue include hematopoietic stem cells, neural stem cells, pancreatic stem cells, and the like.

After the stem cells are separated and cultured from different human tissues, the stem cells are detected and identified, and then the stem cells are frozen at the deep low temperature of-196 ℃, so that the stem cells can be revived for reinfusion of patients when clinically needed, and the purpose of treating diseases is achieved.
