Immunofluorescence analysis of primary cells in LG1 and LG50. a CK8/18 was positive in LG1 and LG50 primary cells. LG1 and LG50 primary cells were fixed and subjected to immunofluorescence analysis. Sections were stained as described in “Methods” section using anti-CK8/18 followed by FITC-conjugated anti-rabbit IgG. Nuclei were counterstained with DAPI (Bar:15 μm). b Napsin A was positive in LG1 and LG50 primary cells. LG1 and LG50 primary cells were fixed and subjected to immunofluorescence analysis. Sections were stained as described in “Methods” section using anti-NapsinA followed by FITC-conjugated anti-rabbit IgG. Nuclei were counterstained with DAPI (Bar:15 μm). c TTF1 was positive in LG1 and LG50 primary cells. LG1 and LG50 primary cells were fixed and subjected to immunofluorescence analysis. Sections were stained as described in “Methods” section using anti-TTF1 followed by FITC-conjugated anti-rabbit IgG. Nuclei were counterstained with DAPI (Bar:15 μm)
