MSCs are a diverse group of adult stem cells with pluripotent capabilities, present in various tissues throughout the human body, including bone marrow, adipose tissue, and other organs. These remarkable cells possess the ability to renew themselves and transform into multiple cell types such as osteoblasts, chondrocytes, and adipocytes. Extensively researched and utilized in regenerative medicine, MSCs also exhibit anti-inflammatory and immunomodulatory properties that effectively regulate immune responses while facilitating tissue repair and regeneration. MSCs can be glycoengineered to display azide groups on their surface, which enables them to maintain their ability to target tumors. In vivo click chemistry based on dibenzocyclooctyne (DBCO) can then be used to specifically target these glycoengineered MSCs. At CD BioGlyco, we provide a variety of types of GlycoCLICK™-based Labeling Service, including the MSC labeling service.
We commonly employ synthetic azide labeling agents for MSC cell labeling. For instance, Ac4ManNAz serves as an azide labeling reagent, facilitating the introduction of the azide moiety onto the cell surface through MSC treatment. This labeling method does not affect the migration, differentiation, and proliferation potential of MSCs and does not have an impact on the multidirectional differentiation potential of the cells. In addition, the labeled MSCs still maintained their original phenotypic characteristics, and the surface labeling agent did not change the expression of the surface markers of the cells, nor did it affect the biological properties and phenotypic characteristics of the cells.

Results: This article focuses on a cellular platform called "glycoengineered MSCs" for the two-step targeting of solid tumors. Glycoengineered MSCs express unnatural azo groups on their surface, and then these cells are used as target organs to deliver targeted drugs, such as fluorescent dyes or nanoparticles, to the tumor cells via bioorthogonal copper-free click chemistry, thereby improving targeting and therapeutic efficacy. This two-step targeting strategy can be extended to a variety of drugs and monoclonal antibodies, etc., used in the clinic. Also, this paper found that this strategy can significantly reduce tumor growth and improve survival. The researchers experimentally verified the therapeutic effect of this cell platform in a mouse model and explored its potential clinical applications.
