CD24 expression in mammospheres. (a) Mammospheres from pleural effusion PE14 and (b) cells from disrupted PE14 mammospheres differentiated in the presence of serum were stained for CD24 expression using the SWA11 antibody, and binding was visualised using rabbit anti-mouse Alexa 488-conjugated antibody (left panels). Right panels are the same cells stained with DAPI (4,6-diamidino-2-phenylindole dihydrochloride). PE, pleural effusion.
