Schematic diagram of mesenchymal stem cells (MSCs) encapsulated with 3D β-cyclodextrin poly(organophosphazene) (β-CD PPZ), adamantane-TGF, and HAV (Ad-TGF and Ad-HAV). The above molecules and cells were mixed to form a 3D thermosensitive hydrogel. After their injection, it was possible to convert the liquid into a gel state at body temperature. The fate of the MSCs can be controlled by varying the stoichiometric ratio of the different molecules. Adapted with permission from Hong et al. (2019).
