Photopolymerization of cell-laden gelatin methacryloyl hydrogels using a dental curing light for regenerative dentistry

Tissue engineering and regenerative medicine consist of delivering cells and bioactive agents (i.e. growth factors, nucleic acids) to injured sites to promote and restore tissue function [1 –3]. Hydrogels, which are highly hydrated natural and synthetic biomaterials that closely replicate the structural and biological characteristics of the native extracellular matrix (ECM), have long been proposed as ideal candidates for cell delivery in regenerative medicine and dentistry [4]. Thei r characteristics, such as biocompatibility, biodegradability, tunable physical and chemical properties, and ease of fabrication, have made them attractive biomaterials for biomedical applications [5–7].
