仪器设备-功能用途
由于传统模型的不足:传统的体外2D细胞模型和体内动物模型常用于评估药物的安全性和有效性,但它们存在明显的缺点。例如,体内动物模型构建耗时,而体外2D细胞模型缺乏体内微环境,无法进行准确评估。
尽管体外3D细胞模型,如细胞球和类器官具有优势,但它们的培养过程漫长且手动,引入了个体差异和高成本。此外,静态培养中的3D模型缺乏构建微生理系统的流体连接。
作为一种动态多器官微生理系统【微生理系统,也称为器官芯片(organ-on-a-chip)技术】,通过模拟器官功能和不同器官间通信,为研究药物的药效学、药动学和整体药物反应提供了新的视角,在疾病建模和药物筛选方面显示出巨大潜力。

文献和实验approaches have been applied to ensure proper medium supply, namely orbital shaking,11 spinning flasks6 and mini-bioreactors.10 However, applying fluidic systems (micro- or millifluidic) have not been considered, so far. In case of the hMOs, we hypothesize that keeping organoids under continuous orbital shaking as per published protocols5 might not be sufficient to ensure a proper supply of nutrients and oxygen. Therefore, to improve the quality of hMOs we investigated the effects of applying a continuous medium flow during culture. In this study we used the “Quasi Vivo” (QV, Kirkstall, UK) millifluidic system rather than a microfluidic device14 for a number of reasons. First, following the concept of allometry, the size of an organoid should range between approximately 0.5 to 2 mm in order to exhibit physiologically scaled metabolism (oxygen consumption).15,16 In addition, millifluidic systems such as the QV allow the application of relatively high flow rates ensuring proper nutrient and oxygen supply without exposing the organoid to a high shear force due to the flow itself. This is due to a well-like design in which the medium inlet and outlet are located in the chamber lid whereas the organoid is placed a variable distance from the medium inlet.17,18 Finally, given their high volume to surface ratio, millifluidic systems do not require frequent media changes, thus organoid manipulation is reduced to a minimum during culture. Besides various applications in 2D cultures, the QV millifluidic system has been successfully used to culture liver organoids13,19 and 3D cardiac constructs20 derived from human (adult) stem cells. In this study, we established a stable midbrain organoid culture under millifluidic conditions and compared it to the state-of-the-art procedure of continuous orbital shaking using both a computational fluid dynamics (CFD) and an experimental approach. The CFD analysis was performed to determine if differences in calculated oxygen profiles in the two experimental set-ups could be used to expla
气体交换,”Synthecon公司的首席科学家Stephen Navran说。“进入这一系统的细胞很快能够聚集成为3D细胞球体。当然也可以加入多种支架物质使细胞得以粘附。该系统的独特之处在于,在RCCS中维持悬浮3D结构所需的机械力非常小,能够将细胞损伤降到最低。此外,旋转的动态培养比依赖于扩散作用的静态培养系统更具优势,能够是细胞更充分的接触到营养物质和氧气。”据Navran介绍,由于缺乏血液供给,所有3D培养系统都存在一定的局限性。“这通常意味着3D细胞结构的中心部分缺乏氧气和营养,并最终会导致细胞坏死。虽然RCCS
