TLDR 3D bioprinting shows promise for skin regeneration but needs more development to fully replicate natural skin.
Recent advances in 3D bioprinting for skin tissue regeneration have shown promise in creating skin-like structures that facilitate vascular network formation, nerve regeneration, and the regrowth of skin appendages such as hair follicles. The technology is particularly beneficial for addressing chronic wounds, cosmetically critical areas, and severe burns. However, challenges remain in replicating the full complexity of native skin, including elastin regeneration and immune-material interactions. The review suggests that interdisciplinary collaboration and the integration of stem cell technology, advanced bioink design, and AI-driven optimization are crucial for overcoming these challenges. Various bioprinting technologies, such as inkjet, extrusion-based, laser-assisted, and DLP-based bioprinting, each offer distinct advantages and limitations, indicating that hybrid approaches may be optimal. The document also highlights the potential of bioactive additives and the integration of AI and robotics to enhance precision and efficiency, although extensive validation and collaboration are necessary for clinical application.
