Abstract
Anterior cruciate ligament (ACL) injuries are common sports injuries that typically require surgical intervention. Autografts and allografts are used to replace damaged ligaments. The drawbacks of autografts and allografts, which include donor site morbidity and variability in quality, have spurred research in the development of bioengineered ligaments. Herein, the design and development of a cost-effective bench-top 3D braiding machine that fabricates scalable and tunable bioengineered ligaments is described. It was demonstrated that braiding angle and picks per inch can be controlled with the bench-top braiding machine. Pore sizes within the reported range needed for vascularization and bone regeneration are demonstrated. By considering a one-to-one linear relationship between cross-sectional area and peak load, the bench-top braiding machine can theoretically fabricate bioengineered ligaments with a peak load that is 9× greater than the human ACL. This bench-top braiding machine is generalizable to all types of yarns and may be used for regenerative engineering applications.
期刊介绍：
Regenerative Engineering is an international journal covering convergence of the disciplines of tissue engineering, advanced materials science, stem cell research, the physical sciences, and areas of developmental biology. This convergence brings exciting opportunities to translate bench-top research into bedside methods, allowing the possibility of moving beyond maintaining or repairing tissues to regenerating them. The journal encourages both top-down engineering approaches and bottom-up strategies integrating materials science with stem cell research and developmental biology. Convergence papers on instructive biomaterials, stimuli-responsive biomaterials, micro- and nano-patterning for regenerative engineering, elastomeric biomaterials, hydrogels for tissue engineering, and rapid prototyping and bioprinting approaches are particularly welcome.
The journal provides a premier, single-blind peer-reviewed forum for the publication of original papers, authoritative reviews, rapid communications, news and views, and opinion papers addressing the most important issues and efforts toward successfully regenerating complex human tissues and organs. All research articles feature a lay abstract highlighting the relevance and future impact for patients, government and other health officials, and members of the general public. Bridging the gap between the lab and the clinic, the journal also serves as a dedicated platform for showcasing translational research that brings basic scientific research and discoveries into clinical methods and therapies, contributing to the improvement of human health care.
Topics covered in Regenerative Engineering and Translational Medicine include:
Advanced materials science for regenerative and biomedical applicationsStem cells for tissue regenerationDrug delivery for tissue regenerationNanomaterials and nanobiotechnology for tissue regenerationStudies combining tissue engineering/regeneration with developmental biologyConvergence research in pre-clinical and clinical phases
