Abstract

Mammalian cell culture is widely used for discovery and development. Recently, increasing attention has been paid to the importance of maintaining physiologically-relevant conditions in cell culture. Although oxygen level is a particularly important consideration, it is rarely regulated by experimentalists. The atmospheric O2 levels commonly used in cell culture are significantly higher than those experienced by most mammalian cells in vivo, leaving cells susceptible to oxidative damage, senescence, transformation, and otherwise aberrant physiology. A barrier to incorporating O2 regulation into most cell culture workflows has been the expense of investing in new equipment, as the vast majority of laboratory CO2 incubators do not regulate O2. Here, we describe an inexpensive (

一种可调节O2、CO2和温度的廉价哺乳动物细胞培养箱
哺乳动物细胞培养被广泛用于发现和开发。最近,在细胞培养中保持生理相关条件的重要性得到了越来越多的关注。尽管氧气水平是一个特别重要的考虑因素,但它很少受到实验者的调节。细胞培养中常用的大气O2水平显著高于大多数哺乳动物细胞在体内所经历的水平,使细胞容易受到氧化损伤、衰老、转化和其他异常生理学的影响。将O2调节纳入大多数细胞培养工作流程的一个障碍是投资新设备的费用,因为绝大多数实验室CO2培养箱都不调节O2。在这里,我们描述了一种价格低廉(<CAD 1000)、便携式且用户友好的O2/CO2培养箱,它可以在生理范围内建立和保持生理O2、CO2和温度值。我们使用了一种基于Arduino的方法,将O2和CO2控制添加到温度调节鸡蛋培养箱中。我们的培养箱在商业实验室O2/CO2培养箱中进行了测试。使用Presens-OxoDish技术,我们证明,在5%气相培养箱O2的设定值下,培养基O2平均为5.03(SD=0.03),范围为4.98-5.09%。在培养箱中培养的MCF7、LNCaP和C2C12细胞系显示出正常的形态、增殖和活力。长达一周的培养没有产生污染。因此,我们的培养箱提供了一种在常规哺乳动物细胞培养中维持生理机能的廉价方法。
