讲座内容简介:

Creation of highly organized multicellular constructs, including tissues and organoids, will revolutionize tissue engineering and regenerative medicine. The development of these technologies will enable the production of individualized organs for patient-tailored organ transplantation or individualized tissues for cell-based therapy. These lab-produced high order tissues and organs can serve as disease models for pathophysiological study and drug screening. This lecture will discuss grant challenges in the emerging field of advanced biomanufacturing. The discussions will be more focused on the development of new tissue biofabrication technologies and how these developments will lead to new models of generating tissue organoids, automated and closed systems, systems for a range of needs from cell culture medium formulation to biomaterial formulation, stem cell differentiation and tissue development/assembly, functionality assessment, in- or on-line sensing, product release evaluation, QA/QC, and supply chain. This concept of advanced biomanufacturing shifts the emphasis from massive production of uniform biomedical products to high-volume, small-scale production of customized tissue products that have a short shelf life. These challenges necessitate a radical manufacturing paradigm shift from conventional, centralized, off-the-shelf medicinal products to a new class of cell- and tissue-based products for precision medicine. The ultimate realization of new manufacturing practices for human cell and tissue clinical application demands a decentralized yet standardized model, providing reliable and robust manufacturing at regional facilities. These regional facilities must manufacture, test, store and distribute cell products safely and efficiently to patients as needed. We have developed an innovative tissue assembly technologies for developing islet organoids from human pluripotent stem cells (HPSCs) and technologies needed for printing small diameter blood vessels for transplantation. We showed that islets can be fabricated from hPSCs. The further optimization of the process will enable the biofabrication of human islets. The fabricated islets can be used for diabetes treatment, drug screening/toxicity validation, and pathophysiological study. Along these lines, we have recently successfully developed a new bioink that possess a shear-thinning property ideal for islet 3D bioprinting. We tested the bioink in blood vessel printing and will move to islet printing upon the success of blood vessel printing. In addition, this lecture will discuss grand challenges in workforce training in biomanufacturing.
