AI Technical Summary
The prior art is difficult to effectively preserve nasal mucosal tissue, especially during frozen and resuscitation, which can easily affect the activity and application of stem cells.
It provides a nasal mucosal tissue frozen solution and nasal mucosal tissue preservation kit. The frozen solution is based on DMEM/F12 and contains components such as human serum albumin, DMSO, dextran 40 glucose injection, glucose sodium chloride injection, vitamin C and Thiazovivin. Through specific frozen and resuscitation methods, ensure efficient and safe storage and resuscitation of nasal mucosal tissue.
The safe and efficient freezing and resuscitation of nasal mucosal tissues was achieved. The resuscited stem cells had no significant differences in morphology, cell markers and purity from stem cells obtained in fresh tissue culture, avoiding the pain of multiple tissue collections to the collected persons.
