Open-source library of tissue engineering scaffolds

Tissue engineering as a field may benefit from progressively implementing and spreading the use of stan-dards, conceived to support the repeatability, replicability and efficient comparing of research results among experts in the field worldwide. Considering that scaffolds play a fundamental role in many tissue engineering strategies, it would be interesting to count with an internationally accepted set of geome-tries, acting as a library of lattices, porous materials and scaffolding structures, which could be employed for comparative purposes among materials and manufacturing technologies under development. To this end, an open-source library of tissue engineering scaffolds has been implemented. This library stands out for providing a comprehensive collection of scaffolds blueprints, designed considering the specific fea-tures of most additive manufacturing technologies applicable to tissue engineering and biofabrication. Besides, the library has been developed focusing on FAIR data principles along the development, for pro-moting: Findability, Accessibility, Interoperability and Reusability. The scaffolds are shared as open -source medical devices with the necessary documentation for facilitating their application. Similar initia-tives may be synergically integrated towards an ISO standard on tissue engineering scaffolds.(c) 2022 The Author(s). Published by Elsevier Ltd.
