学术报告1:Light-Assisted 3D Bioprinting of Micro- and Nano-scale Functional Biomaterials

Shaochen Chen, Ph.D.

Professor of NanoEngineering and Bioengineering Departments

Co-Director, Biomaterials & Tissue Engineering Center, Institute of Engineering in Medicine, University of California, San Diego

 

Abstract

The goal of our laboratory is to develop micro- and nano-scale bioprinting techniques for the direct-write of 3D designer scaffolds used for tissue engineering and regenerative medicine. In this webinar, I will present my laboratory’s recent research efforts in femtosecond laser nano-printing and projection 3D bioprinting to create 3D scaffolds using a variety of biomaterials. These 3D biomaterials are functionalized with precise control of micro-architecture, mechanical (e.g. stiffness and Poisson’s ratio), chemical, and biological properties. Design, fabrication, and experimental results will be discussed. Such functional biomaterials allow us to investigate cell-microenvironment interactions at nano- and micro-scales in response to integrated physical and chemical stimuli. From these fundamental studies we can create both in vitro and in vivo tissue models for precision tissue engineering and regenerative medicine.

学术报告2:Three-Dimensional Bioprinting and Evaluation of Process-Induced Cell Injury

Yong Huang, Department of Mechanical and Aerospace Engineering, University of Florida, Gainesville, FL 32611

 

Abstract

Maskless jet-based (including laser- and inkjet-based) three-dimensional (3D) cell printing is a revolutionary advance for printing arbitrary cell patterns as well as creating heterogeneous living constructs. Most importantly, cell printing provides a promising solution to the problem of organ donor shortages by printing 3D tissue/organ constructs for implantation, resulting in what is known as organ printing. Unfortunately, process-induced thermomechanical injury to cells as well as other biomaterials during printing still poses a significant challenge to ensuring a satisfactory post-transfer cell viability. As previous studies show, process-induced thermomechanical loading can dramatically increase the cell mortality rate if printing conditions are not properly selected.

Using a representative laser cell printing technology (modified laser-induced forward transfer) as a jet-based model system, we have been addressing the aforementioned printing-induced cell injury challenge by studying 1) the process-induced cell thermomechanical loading profiles during the cell droplet formation and landing processes, two key processes during cell printing; and 2) the post-transfer cell viability based on the process-induced thermomechanical loading profiles. In this talk, the perspective of ongoing cell printing research is first introduced. Then the modeling of the laser-induced cell droplet formation and successive landing processes and resultant cell mechanical loading is discussed. Finally, the relationship between the post-transfer cell injury/viability and the mechanical loading information is captured through an apoptosis signaling pathway-based modeling approach.
