Abstract:
Objective To screen the optimum conditions carrying murine melanoma B16 cells in spaceflights without cares.MethodsMurine melanoma cells were cultured on micocarriers and grouped depending on cells concentration, serum concentration, microcarrier number and temperature.After 33 days, B16 cells were stained by Giemsa, observed with phase-contrast microscope and counted for surviving percentage.ResultsThe optimum conditions,in which the surviving percentages were 8% and 10%, were obtained in the experiments.B16 cells were carried in the 20th recoverable satellite orbiting 18 days under the optimum conditions. After recovering, 110 strain monocloned cells were survived and the surviving percentage was 1.1%.ConclusionThe optimum conditions carrying murine melanoma B16 cells in spaceflights without cares seems to be obtained,and it did improve the surviving time and percentage of cells in spaceflights without cares.
