Side-viewing MI needle images obtained for a section of normal human liver, showing labeled biliary ducts and liver progenitor cells. (a) En face OCT needle image obtained after averaging 4 co-located OCT A-scans at each radial position. (b) Corresponding fluorescence needle image. (c) Magnified OCT image of selected region indicated by dashed box in a. (d) Corresponding magnified fluorescence needle image of selected region indicated by dashed box in b. (e) OCT + fluorescence magnified image of selected region. Inset: Magnified view of region indicated by small pink box. (f) Corresponding standard wide-field fluorescence microscopy image for selected region. Inset: High magnification (10 × objective) image of region indicated by pink box confirming liver progenitor cells (LPCs).
