ABSTRACT

BACKGROUND:

In vitro models are widely used in toxicology, pathology, and pharmaceutical research due to their short experimental cycles, low cost, and small species differences compared with animal models. Dynamic three-dimensional tissue culture mode is an important trend in the development of in vitro models. Dynamic three-dimensional culture in vitro models can be achieved by means of driving fluids in microfluidic systems.

OBJECTIVE:

To describe the microfluidic driving methods in the field of microfluidics, their respective advantages and disadvantages, and the application of different driving methods to different tissue culture requirements.

METHODS:

A computed-based retrieval of CNKI and Web of Science databases was performed for the articles concerning dynamic three-dimensional tissue culture and microfluidic driving methods to achieve dynamic culture of cells or tissues. The search terms were “microfluidic; micropump; organ-on-chip; three-dimensional tissue culture” in English and Chinese, respectively. RESULTS AND

CONCLUSION:

The microfluidic driving methods include passive driving and active driving. Whereas passive driving includes surface tension pump, osmotic pump and gravity pump. Active driving includes syringe pump and peristaltic pump. Each driving method has its advantages and disadvantages. To achieve accurate control of the medium flow rate in a dynamic three-dimensional tissue culture system, the best choice is to use syringe pumps or valve-type peristaltic pumps. To achieve closed-loop flow of culture medium in a dynamic three-dimensional tissue culture system, the best choice is to use gravity pumps or peristaltic pumps. To fulfill the need for a sterile environment in the experimental process in a dynamic three-dimensional tissue culture system, the best choices are surface tension pumps, gravity pumps, and pneumatic peristaltic pumps. To achieve high-throughput culture in dynamic three-dimensional tissue culture systems, the best choices are surface tension pumps, gravity pumps and pneumatic peristaltic pumps.
