- Prof. Woo-Jae Jung, developed a bioinspired approach to create collagen-like materials Prof. Woo-Jae Jung research team published thesis 'Biomimetic Self-Templated Hierarchical Structures of Collagen-Like Peptide Amphiphiles' on 'Nano Letters'. (*URL: http://pubs.acs.org/doi/full/10.1021/acs.nanolett.5b03313) The research team developed a bioinspired approach to create collagen-like materials through directed evolutionary screening and directed self-assembly. Collagen is major structural protein that consists of human body. It constitutes hard tissue like bone or flexible tissue like skin in accordance of the way the molecule is systematized and make organization. Using this principle, Collagen maintains essential function by modulating biochemical features and mechanical property of various tissues; for example, bone, skin, tendon, ligament, cornea and so on. The main cause that various tissues consisting of same molecules show different features has been recognized that it is due to 'hierarchical structure, but it was difficult to represent the structure because of technical limitation. Also, there has been limitation on application of Collagen copying materials because of that reason. Prof. Woo-Jae Jung research team succeeded in representing various imitating structures of body by developing the method that concentrates Collagen-like Peptide and induces molecular assembly phenomenon, and then stacks up sequentially various structures created in solution. The result of the research is expected to contribute to development of next generation body materials and the other areas. College of Biotechnology and Bioengineering

- 2016 SKKU-GUGC Joint Workshop for Furthering Collaboration
- 2016 SKKU-GUGC Joint Workshop for Furthering Collaboration SKKU-GUGC joint workshop for collaboration was held on September 23, 2016 at the Ghent University Global Campus in Songdo, Incheon with an idea to establish ties between two esteemed universities for scholarly and student exchanges. Prof. Han-min Woo (Department of Food Science and Biotechnology), Prof. Hyung-gun Kim (Department of Bio-Mechatronic Engineering) and Prof. Dae-hyuk Kweon (Department of Genetic Engineering) attended the workshop. It is expected to increase the overall awareness of GUGC for our faculty and students from which our university shall explore more possibilities of cooperation not only with GUGC but also with Ghent University, which is the leading university in Belgium being well-known for its academic caliber and reputation world-wide.

- Prof. Kye Won Park's research paper was published in Nature Chemical Biology
- Prof. Kye Won Park's research paper was published in Nature Chemical Biology Increasing the thermogenic activity of adipocytes holds promise as an approach to combating human obesity and related metabolic diseases. We identified induction of mouse PR domain containing 4 (Prdm4) by the small molecule butein as a means to induce expression of uncoupling protein 1 (Ucp1), increase energy expenditure, and stimulate the generation of thermogenic adipocytes. This study highlights a Prdm4-dependent pathway, modulated by small molecules, that stimulates browning of white adipose tissue. In conclusion, we showed that Prdm4 knockdown in adipose tissue exacerbated diet-induced obesity, revealing adipose-specific effects of Prdm4 in obesity and thermogenesis. On the basis of this study, we expect that Prdm4 regulation by natural or synthetic compounds could be an alternative therapeutic approach for obesity and metabolic diseases.

- YoungWon Koo(Senior year of Biomechatronic Eng.)'s research paper was published in Biofabrication
- YoungWon Koo(Senior year of Biomechatronic Eng.)'s research paper was published in Biofabrication YoungWon Koo(Senior year of Biomechatronic Eng.) "New strategy for enhancing in situ cell viability of cell-printing process via piezoelectric transducer-assisted three-dimensional printing." Tissue engineering has become one of the great applications of three-dimensional cell printing because of the possibility of fabricating complex cell-laden scaffolds. Three typical methods (inkjet, micro-extrusion, and laser-assisted bio-printing) have been used to fabricate structures. Of these, micro-extrusion is a comparatively easymethod, but has some drawbacks such as low in situ cell viability after fabricating cell-laden structures because of the highwall shear stress in micro-sized nozzles. To overcome this shortcoming,we suggest an innovative cell printingmethod, which is assisted by a piezoelectric transducer (PZT). The PZT assistance in the dispensing process enhances the printing efficiency and cell viability by decreasing thewall shear stress within a nozzle because the PZT effect can lower the shear viscosity of the bioink viamicro-scale vibration. In this study, 5 wt% cell-laden alginatewas used as a bioink, and various PZT conditions (frequencies up to ∼400 Hz and amplitudes up to∼40.5 μm) were simultaneously applied to the cell-printing process to examine the effectiveness of the PZT. The PZT-assisted cell-printing method was found to be highly effective in direct cell printing and could achieve cell-laden structureswith high in situ cell viability. ... The cell damage that occurs during the cell-printing process is primarily the result of the wall shear stress in the narrow printing nozzle. An innovative method of enhancing the initial cell viability was proposed using a direct cell printing method assisted by a PZT system, which could significantly reduce the wall shear stress of the bioink within the printing nozzle. By manipulating various PZT conditions (frequency and amplitude), we could successfully attain an optimal processing condition, which allowed a relatively high initial cell viability for the printed cell-laden struts. Based on the results, we can confirm that the method is one solution for increasing the in situ cell viability in the cell-printing process. Furthermore, the ability to construct a highly porous 3D structure with an appropriate thickness could demonstrate that the cellprinting method may have substantial potential for the successful development of cell-embedded 3D porous structures.
