comparative proliferation efficiencies of cells in different culture modes elucidated that the

proliferation efficiency of cells in the microtissues prepared by the dynamic culture method was

slightly faster than that of those subjected to the static culture mode because of the more significant

transfer of nutrients, oxygen, and waste .

staining of cells treated with different concentrations of suspensions for 24 h (Green: live; Red:

dead). The cytotoxicity of cells treated with different concentrations of suspensions for different

times was analyzed by CCK-8 assay (B) MC3T3-E1. (C) C518 (n=3).
