Given the current limitations of conducting biological research in space, a few options exist for subjecting cell culture to simulated microgravity (SMG) on Earth. These options vary in their methods, principles, and suitability for use with suspension cell culture. Here, a cell culture method is described for subjecting lymphocytes to simulated microgravity using a commercially available rotary cell culture system, also known as a 2D clinostat or a rotating wall vessel (RWV) device. This cell culture method utilizes the principle of time-averaged gravity vector nullification to simulate microgravity by rotating the cells on a horizontal axis. The cells cultured in this system can be harvested and utilized in many different experimental assays to assess the effects of simulated microgravity on cellular function and physiology. The culturing technique may vary slightly depending on the cell type or line that is used, but the method described here may be applied to any suspension-type cell culture.
鉴于目前在太空中进行生物研究的局限性,有几种选择可以在地球上对细胞培养物进行模拟微重力(SMG)处理。这些选择在方法、原理和对悬浮细胞培养的适用性方面有所不同。在这里,描述了一种使用商业上可获得的旋转细胞培养系统(也称为二维回旋器或旋转壁容器(RWV)装置)使淋巴细胞经历模拟微重力的细胞培养方法。该细胞培养方法利用时间平均重力矢量抵消的原理通过在水平轴上旋转细胞来模拟微重力。可以收获在该系统中培养的细胞,并将其用于许多不同的实验测定中,以评估模拟微重力对细胞功能和生理学的影响。培养技术可能会根据使用的细胞类型或系略有不同,但这里描述的方法可以应用于任何悬浮型细胞培养。
