The Effect of Polymeric Nanofibers Used for 3D-Printed Scaffolds on Cellular Activity in Tissue Engineering: A Review

Promising scaffolds for developing advanced tissue engineering architectures have emerged in recent years through the use of nanofibers and 3D printing technologies. Despite this, structural integrity and cell proliferation are highlighted as fundamental challenges for design scaffolds and future prospects. As a biomimetic scaffold, the nanofiber-reinforced hydrogels demonstrated a better compressive modulus and cell growth. Our review focuses on recent promising advances in the development of 3D-printed hydrogels containing polymeric nanofibers that can improve cell-material interaction in biomedical applications. Moreover, an effort has been made to induce studies with diverse types of scaffolds for various cells. Additionally, we discuss the challenges and future prospects of 3D-bioprinted reinforced hydrogels with nanofibers in the medical field, as well as high-performance bioinks.
