A 3D Bioprinted Decellularized Extracellular Matrix/Gelatin/Quaternized Chitosan Scaffold Assembling with Poly(ionic Liquid)s for Skin Tissue Engineering

Investigators prepared a tissue-specific ECM-based bioink, and dECM/Gel/QCS 3D scaffold assembling with poly(ionic liquid)s was obtained by an extrusion 3D bioprinting technology and dynamic hydrogen bonding method.
