Alginate lyase-contained bioinks promote the degradation of 3D constructs in vitro and in vivo. A. Schematic illustration of bioprinting process using alginate lyase-contained bioinks; B. H&E staining of bioprinted lattice with different concentrations of alginate lyase cultured for 14 days (Scale bars: 500 μm); C. H&E staining of subcutaneously engrafted bioprinted constructs with alginate lyase of different concentrations at 14 days post-operatively (scale bar: 500 μm). Cited from Ref. [52].
