Schematic illustration of the construction of cell cross-linked hydrogels (CxGels). Reactive azide groups are covalently incorporated into cell-surface glycans through the biosynthetic machinery. CxGels are constructed via bioorthogonal click cross-linking reaction between the azide-modified cells and the alkyne-modified polymers
