ABSTRACT
Cell biology experiments in space are indispensable for investigating the effects of microgravity environment on living organisms. As an important technological means of supporting life science researche, space cell bioreactor may directly influence the data quality of space cell biology experiments and research level. To date, space cell bioreactor techniques are still under development, and lack of standard rationale. In this article, the technical progresses of space cell bioreactor were reviewed, by introducing the operational principle of several typical space cell bioreactors, analyzing the mode of culture medium supplying and character of fluid mechanics environment in space, as well as the relevant supporting techniques about the parametric controlling on temperature, dissolved oxygen and pH value and on-line microscopic imaging, so as to discuss the future perspective about space cell bioreactor techniques.
