About Printing cells: Process, application and challenge

3D Bio-Printing prints living cells to build in vitro physiological models. The printed tissue models have been widely applied to regenerative medicine, studying disease pathogenesis, developing molecular therapeutics, and screening drugs. This presentation will review the basic principle of printing cells and report our recent study on printing in vitro physiological models with its application to regenerative medicine, disease study and drug testing. An overview of a cell printing process and enabling printing techniques will be introduced first, followed by examples of printing different tissue models for drug testing, including printing ESCs for formation of embryonic body, printing neuron cells to construct in vitro neural network models for studying DNQX influence, and printing hiPSC cells for hepatocyte differentiation and integration with microfluidics for drug toxicity testing. A case study of printing cancer (Hela) cells to build 3D in vitro tumor models for studying chemoresistance and expressions of genes and tumor markers will also be presented. Comparison of biological data derived from 3D printed in vitro models with 2D planar models in petri-dishes will be given wherever appropriate. A personal opinion on challenges and opportunities of 3D bio-printing will also be given.
