Direct 3D bioprinting of perfusable vascular constructs using a blend bioink

TL;DR: This review studies the use of 3D bioprinting for engineering bone, cartilage, muscle, tendon, ligament, and their interface tissues and the current limitations and challenges in the field are discussed and the prospects for future progress are highlighted.

TL;DR: The recent progress and challenges in 3D bioprinting strategies for cardiac tissue engineering, including cardiac patches, in vitro cardiac models, valves, and blood vessels are discussed.

TL;DR: The composition and synthesis of hydrogels, the character of their absorbed water, and permeation of solutes within their swollen matrices are reviewed to identify the most important properties relevant to their biomedical applications.

TL;DR: The properties of hydrogels that are important for tissue engineering applications and the inherent material design constraints and challenges are discussed.

TL;DR: An integrated tissue–organ printer (ITOP) that can fabricate stable, human-scale tissue constructs of any shape is presented and the incorporation of microchannels into the tissue constructs facilitates diffusion of nutrients to printed cells, thereby overcoming the diffusion limit of 100–200 μm for cell survival in engineered tissues.

TL;DR: Gelatin methacryloyl (GelMA) hydrogels have been widely used for various biomedical applications due to their suitable biological properties and tunable physical characteristics and are demonstrated in a wide range of tissue engineering applications including engineering of bone, cartilage, cardiac, and vascular tissues, among others.
