The effect of simulated microgravity on the expressions of intercellular adhesion molecule 3 (ICAM-3) also known as cluster of differentiation (CD)50 in Jurkat (a) and Jurkat/A4 cells (b) The expression of surface antigens was assessed by flow cytometry. The total number of cells expressing surface antigens on their cell surface was assessed by determining the (MFI) (c). Mouse IgG1-fluorescein isothiocyanate (FITC) was used as the isotype-matched control to exclude any nonspecific staining. The results are expressed as means ± standard deviations. * p < 0.05, as compared with the static controls (n = 5).
