Self-assembled hADSCs/hNSCs spheroids combined with 3D printed M-shaped GelMA/Pu Scaffolds: Creating histologically biomimetic engineered cartilage that meets the characteristics of alar cartilage
{{output}}
Background: Traditional cartilage grafts for nasal alar retraction repair often lack sufficient elasticity and histocompatibility, leading to suboptimal clinical outcomes. To address this challenge, we developed a biomimetic engi... ...
