[0002] As we all know, stem cells (SC) are a type of multipotent cells with self-renewing ability. Under certain conditions, they can differentiate into a variety of APSC multipotent cells. They are a type of primitive cells with self-replication and multidirectional differentiation potentials, that is, stem cells maintain an undirected differentiation state and have the ability to proliferate. Under appropriate conditions or given appropriate signals, they can differentiate into a variety of functional cells or tissues and organs. The medical community calls them "universal cells". Stem cells are widely used in the medical field.

[0003] The traditional general storage method of stem cells is to "isolate and culture stem cells from different human tissues, then test and identify them, and then freeze them at a deep low temperature of -196°C" so that the stem cells can be revived and re-infused into patients when clinically needed to achieve the purpose of treating the disease.
