Figure 3From: Differential baseline and response profile to IFN-γ gene transduction of IL-6/IL-6 receptor-α secretion discriminate primary tumors versus bone marrow metastases of nasopharyngeal carcinomas in culture Levels of IL-6Rα detected in the spent media by nontransduced NPC cell lines at day 3 cultures. Results of IL-6Rα secreted are expressed on the basis of per ml (penal A) and per cell (penal B). The penal of cell lines used were same as those in Figure 2.Back to article page
