Immunostaining for AQP5 (green, acinar marker) and K7 (red, ductal marker) in wounded SMG treated without scaffold (A), or with FH (B), VF-FH (C), L1p-FH (D), LV-FH (E), LF-FH (F) and LVF-FH (G). Unwounded glands served as sham controls (H). Specimens were analyzed using a confocal Zeiss LSM 700 microscope at 40× magnification (bars = 200 μm). Positive area of AQP5 (I) and the ratio of acinar and ductal structures (J) were calculated on day 20 post-surgery using ImageJ and analyzed using one-way ANOVA (*p < 0.01, n = 12) and Dunnett’s post-hoc test for multiple comparisons to the L1p-treated group.
