Completely self-contained cell culture system: from storage to use.
In vitro cell culture systems provide researchers the appropriate tools for effectively studying cell growth and differentiation, understanding cellular response to specific environmental stimuli, and elucidating the function of heterologous biological molecules produced from expression systems. All in vitro cell culture systems require a specific culture media formulated to the nutritional and metabolic requirements of the particular cell type to be cultured. However, the complexity of these systems varies depending on the model organism origin of the cells being cultured (e.g., bacteria, plants, yeast or animal). Unlike bacteria and yeast, mammalian cell cultures require sophisticated auxiliary technologies (e.g., controlled gas mixtures and pressure flow systems, specialized facilities and equipment) and careful handling by trained personnel. These complex requirements pose a limitation to transferring cells to and from remote field locations for investigations. Furthermore, this limitation is a technical hurdle in the development of technologies involving use of live cells (e.g., cytosensors). We identified a novel and unrealized feature in the conventional cell culture system that may be exploited to adapt simple existing technologies to form a portable apparatus for storing and growing cells. The approach we describe is a completely self-contained cell culture system that not only will bring down the cost of culturing cells but also will expand cell culture applications in medicine, research, environmental health, and safety.
