| 5 | U-IMPACT:a universal 3D microfluidic cell culture platform显示文摘The development of organs-on-a-chip has resulted in advances in the reconstruction of 3D cellular microenvironments.However,there remain limitations regarding applicability and manufacturability.Here,we present an injection-molded plastic array 3D universal culture platform(U-IMPACT)for various biological applications in a single platform,such as cocultures of various cell types,and spheroids(e.g.,tumor spheroids,neurospheres)and tissues(e.g.,microvessels).The U-IMPACT consists of three channels and a spheroid zone with a 96-well plate form factor.Specifically,organoids or spheroids(~500μm)can be located in designated areas,while cell suspensions or cellladen hydrogels can be selectively placed in three channels.For stable multichannel patterning,we developed a new patterning method based on capillary action,utilizing capillary channels and the native contact angle of the materials without any modification.We derived the optimal material hydrophilicity(contact angle of the body,45–90°;substrate,<30°)for robust patterning through experiments and theoretical calculations.We demonstrated that the U-IMPACT can implement 3D tumor microenvironments for angiogenesis,vascularization,and tumor cell migration.Furthermore,we cultured neurospheres from induced neural stem cells.The U-IMPACT can serve as a multifunctional organ-on-achip platform for high-content and high-throughput screening. | Seung-Ryeol Lee Youngtaek Kim Suryong Kim Jiho Kim Seonghyuk Park Stephen Rhee Dohyun Park Byungjun Lee Kyusuk Baek Ho-Young Kim Noo Li Jeon | 2022 | Microsystems & Nanoengineering2022，8，6： | 0 |
| 6 | Propagating acoustic waves on a culture substrate regulate the directional collective cell migration显示文摘Collective cell migration plays a critical role in physiological and pathological processes such as development,wound healing,and metastasis.Numerous studies have demonstrated how various types of chemical,mechanical,and electrical cues dictate the collective migratory behaviors of cells.Although an acoustic cue can be advantageous because of its noninvasiveness and biocompatibility,cell migration in response to acoustic stimulation remains poorly understood.In this study,we developed a device that is able to apply surface acoustic waves to a cell culture substrate and investigated the effect of propagating acoustic waves on collective cell migration.The migration distance estimated at various wave intensities revealed that unidirectional cell migration was enhanced at a critical wave intensity and that it was suppressed as the intensity was further increased.The increased migration might be attributable to cell orientation alignment along the direction of the propagating wave,as characterized by nucleus shape.Thicker actin bundles indicative of a high traction force were observed in cells subjected to propagating acoustic waves at the critical intensity.Our device and technique can be useful for regulating cellular functions associated with cell migration. | Chikahiro Imashiro Byungjun Kang Yunam Lee Youn-Hoo Hwang Seonghun Im Dae-Eun Kim Kenjiro Takemura Hyungsuk Lee | 2021 | Microsystems & Nanoengineering2021，7，6： | 0 |
