Abstract: Provided is a preservation solution for low-temperature preservation of adipose-derived mesenchymal stem cells. The preservation solution contains a compound electrolyte injection, a glucose and sodium chloride injection, vitamins, and amino acids. The preservation solution can be used for preserving adipose-derived mesenchymal stem cells at a low temperature, so as to effectively maintain the viability of adipose-derived mesenchymal stem cells, and meet clinical requirements.

Abstract: Compositions and methods for the preservation and long-term storage of viral vectors such as lentiviral vectors are provided.

Abstract: The present invention relates to the preparation and use of a cell cryopreservation formulation convenient for clinical use. In particular, provided is a cell cryopreservation (freezing) formulation, comprising: (1) a cell; (2) a cryopreservation diluent; the cryopreservation diluent comprising: an aqueous solution of sodium chloride, protective proteins, and dimethyl sulfoxide. The invention also relates to a corresponding cell resuscitation method. The invention adopts a no-wash cryopreservation solution for preparation of a cell frozen preparation, and the cell resuscitation and dilution for clinical use can be carried out by a simple formulating operation.
