    研究成果名稱(中)：發現斑馬魚利用機械波偵測受傷的程度
    研究成果名稱(英)：Mechanical waves identify the amputation position during wound healing in the amputated zebrafish tailfin
    簡要記述(中)：18世紀義大利的生物學家Lazzaro Spallanzani 是第一個發現某些脊椎動物，像是蜥蜴和蠑螈，有很強再生能力。他仔細紀錄了一個奇特現象- 受傷越重，再生越快。這些動物如何偵測受傷發生的位置? 複雜組織的再生速度如何調控? 生物學家至今對此一現象仍然瞭解的很少。林耿慧與陳振輝團隊合作，利用斑馬魚的尾鰭作為模型，開發活體影像工具，觀察到不同的受傷程度會產生不同的傷口癒合反應。在細胞的層級，失去的組織越多，參與傷口癒合的細胞就越多，快速移動的上皮細胞呈現出像是波的行為。他們發現波的傳遞距離，與被切斷尾鰭的長度成正比。但是這個波的本質是什麼？是化學波還是機械波？林耿慧設計實驗，驗證波速會受到組織張力的影響，波的傳遞會互相干涉，支持這個波是機械波。溫福來建立理論模型預測波的行為，發現細胞之間有如彈簧的耦合，機械因素例如阻力的梯度變化，是限制波傳遞的關鍵。他們還發現上皮細胞裡過氧化氫的新功能。作為受傷訊號，過氧化氫可以反映受傷程度、即時控制上皮細胞的移動速度，進而影響波的傳遞距離。
    簡要記述(英)：For over 250 years, biologists have been puzzled by why highly regenerative animals regrow lost appendages at the rate that is proportional to the amount of appendage loss. A team led by Dr. Chen-Hui Chen at the Institute of Cellular and Organismic Biology (ICOB) and Dr. Keng-Hui Lin at the institute of physics (IOP) discovered a ‘mechanical wave’ that governs positional sensing during wound healing and regeneration. This unexpected finding has been published in the journal Nature Physics in June 2023.Highly regenerative animals can regrow lost appendages and the rate of regrowth is proportional to the amount of appendage loss. This century-old phenomenon prompted us to to investigate whether the mechanism of wound healing, as the first stage of regeneration, is responsible for discerning the amputation position. In vitro studies have revealed significant insights into the mechanics of the wound-healing process, including the identification of mechanical waves in collective epithelial cell expansion. It has been suggested that these mechanical waves may also be involved in positional sensing. Here, we perform live-cell imaging on adult zebrafish tailfins to monitor the collective migration of basal epithelial cells upon tailfin amputation. We observed a cell density wave propagating away from the amputation edge, with the maximum traveling distance proportional to the amputation level and cell proliferation at later stages. We developed a mechanical model to explain this wave behaviour, including the tension-dependent wave speed and amputation-dependent traveling distance. Together, our findings point to an in vivo positional sensing mechanism in regenerative tissue based on a coupling of mechanical signals manifested as a traveling density wave.

    研究成果名稱(中)：圓洞井作為三維培養基材
    研究成果名稱(英)：Spherical microwell for 3D cell culture
    簡要記述(中)：林耿慧實驗室近期開發出更新一代的三維細胞培養平台，由圓洞陣列所組成。這個圓洞陣列使用方式非常多樣化，如當圓洞陣列都沒有讓細胞貼附處時，細胞能在圓洞內聚集成類球體結構(spheroid)，但圓洞開口比直徑小，所以球體結構不會掉出來。當只有圓洞內有貼附處時，細胞會被限制在圓洞內，無法爬行出來。他們發現，當纖維母細胞被限制在 100 微米以下的圓洞，細胞就停止分裂，這是第一次展示利用很明確的三維幾何空間來改變細胞週期。這個文章發表在 Biofabrication 12, 025016 (2020)。
    簡要記述(英)：Microwell arrays have emerged as three-dimensional substrates for cell culture due to their simplicity of fabrication and promise for high-throughput applications such as 3D cell-based assays for drug screening. To date, most microwells have had cylindrical geometries. Motivated by our previous findings that cells display 3D physiological characteristics when grown in the spherical micropores of monodisperse foam scaffolds (Lee et al 2013 Integr. Biol. 5 1447–55 and Lin et al 2011 Soft Matter 7 10010–6), here we engineered novel microwells shaped as spherical caps with obtuse polar angles, yielding narrow apertures. When used as bare substrates, these microwells were suitable for culturing cell spheroids; the narrow apertures sterically hindered unattached cultured cells from rolling out of microwells under agitation. When only the walls of the microwell were conjugated with extracellular matrix proteins, cells remained confined in the microwells. Epithelial cells proliferated and burst out of the aperture, and cell polarity was oriented based on the distribution of extracellular matrix proteins in the microwells. Surprisingly, single fibroblast cells in spherical wells of various diameters (40–100 μm) underwent cell-cycle arrest, while cells in circular cylindrical microwells continued to proliferate. Spatial confinement was not sufficient to cause cell-cycle arrest; however, confinement in a constant negative-curvature microenvironment led to cell-cycle arrest. Overall, these investigations demonstrate that this spherical microwell substrate constitutes a novel basic research tool for elucidating how cells respond to dimensionality and microenvironment with radii of curvature at the cellular length scale.

    簡要記述(英)：Designing biomaterials for studying cell-extracellular matrix (ECM) interactions in three dimensions (3D) is key to the biological relevance of observations of cells grown in 3D culture. In recent decades, novel two-dimensional substrates such as compliant gels with patterned proteins have provided many useful insights into how adhesive and mechanical cues drive cellular behavior. Here, we extend cell culture into the third dimension by engineering uniform pores in compliant gels; these pores are treated with fibronectin to pattern ECM proteins as a spherical shell. The rigidity of the 3D microenvironment is controlled by choice of base gels used to assemble the scaffolds. Fibroblasts exhibit quantitative differences in morphology and cytoskeletal architecture following culture in our 3D scaffolds versus 2D substrates. Our new technology offers independent control over factors such as three-dimensionality, curvature, biochemical composition, and the mechanical stiffness of the substrate, all of which make critical contributions to the formation of cell adhesions in 3D.

    簡要記述(英)：We demonstrate high-throughput fabrication of gelatin-based ordered cellular solids with tunable pore size and solid fraction. This process involves
    generating high air fraction and monodisperse liquid foam with a flow-focusing microfluidic device. The monodisperse liquid foam was further processed into open-cell solid foam, which was used as tissue-engineering scaffolds for cell culture. Three distinct cell types were cultured under these conditions and displayed appropriate physiological, morphological, and functional
    characteristics. Epithelial cells formed cyst-like structures and were
    polarized inside pores, myoblasts adopted a tubular structure and fused into myotubes, and fibroblasts exhibited wide varieties of morphologies depending
    on their location inside the scaffolds. These ordered cellular solids therefore make possible the study of pore-size effects on cells and the investigation of mechanical properties of microscopic foam structures.

    簡要記述(中)：一般細胞在身體組織裡是生長在一個三維環境, 所以在三維環境下培養細胞是了解細胞如何形成組織的關鍵,在組織工程裡, 科學家製作了各種鷹架來做這件事. 但要有系統性的去了解細胞環境對細胞的影響, 鷹架的孔洞均一性就很重要.我們利用微流體通道來生產大小相同的泡泡, 這些泡泡會堆疊成有序的晶格結構, 我們用這做為樣板, 把泡泡結構變成多孔性開放的固體材料, 並做為鷹架. 在這樣的鷹架上培養細胞, 並觀察它們生長, 發現優於傳統不均勻的鷹架. 我們相信, 這個方法在三維細胞培養與了解細胞固體的力學性質的研究上有很大的應用.
    簡要記述(英)：Tissue cells in the body grow in a three-dimensional mesh called an extracellular matrix. It is important to create a 3D environment for the study of tissue formation. In tissue engineering, scientists fabricate all kinds of scaffold to achieve this purpose. However, to study the cell-matrix interaction systematically, it is important to have a uniform scaffold. We utitlize the microfluidic to generate monodisperse bubbles which assemble into crystalline structures. We use the foam crystal as a template and then turn it into porous gel of uniform pore size. We culture cells inside the uniform solid foam and the cell proliferate faster in comparison with the traditional non-uniform scaffold. We believe this method is very useful in the studies of 3D cell cultures and cellular solids.
