1. Histopathologic characteristics in HL-mice and HL-HPS-mice.
Histopathologic characteristics in HL-mice and HL-HPS-mice. H&E staining (A) and Fontana–Masson staining (B) of epithelia from HL-mice and HL-HPS-mice are presented. Melanin with brown color (right photograph in A) and black color (B) was detected. C, percentages (mean ± SD) of melanin density (melanin-containing area per measured area) in the epithelia from HL-mice and HL-HPS-mice were analyzed by the software program WinROOF after Fontana–Masson staining. **, significantly different (P < 0.01) from the control by the Mann–Whitney U test.
