Magnetically Driven Formation of 3D Freestanding Soft Bioscaffolds

This review discusses the principles, materials, and applications of melt electrowriting-based 4D printing for creating biomimetic scaffolds, but reports no new clinical results; it highlights recent advancements and remaining challenges in the field.

This review article summarizes recent advancements in biomimetic scaffolds, highlighting their promise in tissue engineering and personalized medicine, particularly for skin and musculoskeletal system regeneration, while emphasizing the need for more extensive research to ensure their safety for human use.

In this study, tubular 3D bioprinted structures made from sodium alginate and gelatin, containing NIH/3T3 fibroblast cells, demonstrated the ability for cell growth and network formation over 6 weeks, although structural tensile strength decreased with cell growth and polymer degradation.

This study reported that 4D-printed, aliphatic polycarbonate-based scaffolds supported adipose tissue engineering by allowing adipocyte infiltration and neovascularization in vivo, indicating potential for effective adipose tissue repair.
