Title:
UMBILICAL CORD MESENCHYMAL STEM CELL CRYOGENIC VIAL CONTAINING POLYGALACTURONIC ACID COATING
Document Type and Number:
WIPO Patent Application WO/2022/099467
Kind Code:
A1
Abstract:
Provided is an umbilical cord mesenchymal stem cell cryogenic vial containing a polygalacturonic acid coating. The inner wall of the main body of the cryogenic vial is provided with a coating, and the coating is formed by polygalacturonic acid. When umbilical cord mesenchymal stem cells are subjected to cryogenic storage by using the cryogenic vial, the number and activity of cells that are subjected to cryogenic storage at -80℃ for 6 months do not decrease significantly.
