Editorial: Novel composites and multi-material assembly approaches for tissue regeneration

In this Research Topic entitled “Novel composites and multi-material assembly approaches for Tissue Regeneration,” we aimed to bring forth new insights and ideas from our peers who combine various materials to create complex tissue-regeneration solutions. As we wrap up this topic for now, we are happy to report that we were able to attract several interesting research studies, which generated significant new insight for our field. On composite materials, we received studies combining collagen composites with other biological factors, native extracellular matrix composites with hydrogels and cellulose-hydrogel composites among biologically sourced materials; and polymer-drug, polymer-polymer and polymer-hydrogel composites among (mostly) synthetic materials. On multi-material fabrication approaches, the papers received covered pressure based extrusion (bioprinting), composite material electrospnning, and an automated sheet rolling technique to obtain 3D constructs from electrospun films.
