Macroscopic assessment
The extent of depigmentation was evaluated in terms of the percentage of
affected area, as described previously, and was scored as follows: 0, no
depigmentation (0%); 1.0—10% depigmented area; 2, 10%–25%; 3,
25%–75%; 4, 75%–100%; and 5, 100%. The final vitiligo score of
each experimental group was calculated as the average for individual
mice.
