3D-Bioprinted GelMA/Gelatin/Amniotic Membrane Extract (AME) Scaffold Loaded with Keratinocytes, Fibroblasts, and Endothelial Cells for Skin Tissue Engineering

Researchers fabricated and characterized a bi-layered GelMA-gelatin scaffold using 3D bioprinting. The upper section of the scaffold was encompassed with keratinocytes to simulate the epidermis, while the lower section included fibroblasts and HUVEC cells to mimic the dermis.
