Design of photocurable, biodegradable scaffolds for liver lobule regeneration via digital light process-additive manufacturing.

The regeneration of damaged or lost tissue is considered to be a critical step toward realizing full organ regeneration in modern medicine. Although surgical techniques continue to advance, treatment for missing tissues in irregular wounds remains particularly difficult. With increasing interest in the application of additive manufacturing in tissue engineering, the fabrication of customized scaffolds for the regeneration of missing tissue via three-dimensional (3D) printing has become especially promising.
