Hemoglobin Expression in Nonerythroid Cells: Novel or Ubiquitous?

Figure 2

Indirect immunofluorescence localization of Hb-α and Hb-β subunits in cervicovaginal epithelial cells. The upper panel shows the expression of Hb-α (red) in VK2/E6E7 cells, control (a), H₂O₂ treated (b), LPS treated (c), and negative control (d). The lower panel shows the expression of Hb-β (green) in VK2/E6E7 cells, control (e), H₂O₂ treated (f), LPS treated (g), and negative control (h). Both subunits were found to be present in the cytoplasm of these cells. Nucleus was stained with DAPI (blue). The figure shown is the representative pictures from three independent experiments (magnification ×63).
