Chronic wounds, such as diabetic foot ulcers, pressure ulcers, and venous ulcers, pose significant clinical challenges and burden healthcare systems worldwide. The advent of 3D bioprinting technologies offers innovative solutions for enhancing chronic wound care. This scoping review evaluates the applications, methodologies, and effectiveness of 3D-printed bioinks in chronic wound healing, focusing on bioinks incorporating living cells to facilitate wound closure and tissue regeneration. Relevant studies were identified through comprehensive searches in databases, including PubMed, Scopus, and Web of Science databases, following strict inclusion criteria. These studies employ various 3D bioprinting techniques, predominantly extrusion-based, to create bioinks from natural or synthetic polymers. These bioinks are designed to support cell viability, promote angiogenesis, and provide structural integrity to the wound site. Despite these promising results, further research is necessary to optimize bioink formulations and printing parameters for clinical application. Overall, 3D-printed bioinks offer a transformative approach to chronic wound care, providing tailored and efficient solutions. Continued development and refinement of these technologies hold significant promise for improving chronic wound management and patient outcomes.
慢性伤口,如糖尿病足溃疡、压疮和静脉溃疡,给全球医疗系统带来了重大的临床挑战和负担。3D生物打印技术的出现为改善慢性伤口护理提供了创新解决方案。本综述评估了3D打印生物墨水在慢性伤口愈合中的应用、方法和有效性,重点关注含有活细胞以促进伤口闭合和组织再生的生物墨水。通过在包括PubMed、Scopus和Web of Science数据库在内的数据库中进行全面检索,并遵循严格的纳入标准,确定了相关研究。这些研究采用了各种3D生物打印技术,主要是基于挤压的技术,从天然或合成聚合物中制造生物墨水。这些生物墨水旨在支持细胞活力、促进血管生成,并为伤口部位提供结构完整性。尽管取得了这些有前景的结果,但仍需要进一步研究以优化生物墨水配方和打印参数用于临床应用。总体而言,3D打印生物墨水为慢性伤口护理提供了一种变革性方法,提供了量身定制且高效的解决方案。这些技术的持续开发和完善对于改善慢性伤口管理和患者预后具有重大前景。
