Fig. 6From: Identification of the xenograft and its ascendant sphere-forming cell line as belonging to EBV-induced lymphoma, and characterization of the status of sphere-forming cellsDual analysis of cells with regard to their ability both to bind antibodies to the surface marker CD90 and to internalize TAMRA-DNA in ex vivo culture. a Different cells in direct contact. b Confluent cells. 1–5—Fluorescence intensity profiles (CD90 (APC)—yellow line, TAMRA—red line), and a transmitting light profile (white line) built across the interacting cells; 6—APC and TAMRA fluorescence co-localization profile. The site with equal intensity of both signals is denoted in blue; 7–11—images of confluent cells obtained in vitro using the laser confocal microscopeBack to article page
