Abstract
Bioprinting, especially using Laser Induced Forward Transfer (LIFT), shows significant potential for creating living tissues by precisely printing cells and biomaterials. This technique fabricates structures that mimic native tissue functions, useful in regenerative medicine. In this study, various cell-laden bioinks were printed with LIFT, utilizing a Nd:YAG laser at 532nm to create ex vivo 3D structures. Detailed rheological characterization and optimized laser parameters ensured accurate cell depositions. Mouse-derived urothelial and smooth muscle cells were printed within biomaterials like Platelet Lysates methacrylated (PLMA) and hydrogels, forming a 3D bladder graft. LIFT bioprinting demonstrates significant advantages for controlled tissue fabrication.
