Objective To establish a carrying system for space cellular experiment suitable for astronaut to carry out cellular experiments on Shenzhou-6 mission. Methods The cell carrying sample bag, sample box and sample box integrated package were designed. Primary cardiomyocytes and osteoblasts culture and ground model experiment in the simulated environment of space cabin were performed. With man-tended, the cellular experiment was carried out on the orbit, Results After 5 d space flight, the returned cell samples were analyzed. The results demonstrated that the system was of good safety, reliability and applicability, as well as satisfied the demands of analyzed samples. Conclusion After Shenzhou-6 space flight, it is showed that this system fits for small loading, multi-cells and man-tended carrying mission, and can satisfy the demand of the first man-tended space cellular experiments carried out on the Shenzhou-6 spacecraft.
