Abstract

Bioprinting has emerged in recent years as an attractive method for engineering of 3D tissues and organs in the laboratory, which can subsequently be implemented in a number of regenerative medicine applications. Currently, the primary goals of bioprinting are to (1) create complete replacements for damaged tissues in patients and (2) rapidly fabricate small-sized human-based tissue models or organoids for high-throughput diagnostics, pathology modeling, and drug development. Regardless of which of these end applications are targeted, successful biofabrication using bioprinting technology relies on a set of four essential characteristics that must be optimized. In this chapter, we will discuss and evaluate integration of cell sourcing, biomaterial support, bioprinting device compatibility, and postfabrication tissue support, and how these characteristics are mandatory considerations for practical realization of viable and functional tissue engineered organ and organoid structures.

1. An introduction to bioprinting

Bioprinting has emerged as a flexible tool in regenerative medicine with potential in a variety of applications. Bioprinting is a relatively new field within biotechnology that can be described as a robotic additive biofabrication that has the potential to build or pattern viable organ-like or tissue structures [1]. In general, bioprinting uses a computer-controlled 3D printing device to accurately deposit cells and biomaterials into precise geometries with the goal being the creation of anatomically correct biological structures. Generally, bioprinting devices have the ability to print cell aggregates, cells encapsulated in hydrogels or viscous fluids, or cell-seeded microcarriers – all of which can be referred to as “bioink” – as well...
