g, Numbers of GFP-marked melanocytes per scale area from young (7 wo, n = 29 scales) and aged (22 mo, n = 24) Dct-H2B-GFP tg mice. i, Representative immunofluorescence images of COL17A1 and ITGA6 in the tail scale area from cont, Col17a1 cKO, Itga6 cKO and Col17a1, Itga6 dcKO (11 wo) mice. k, Numbers of GFP-marked melanocytes per tail scale area (melaninhigh/low) from control (n = 5), Col17a1 cKO (n = 4) and Itga6 cKO (n = 6) combined with Dct-H2B-GFP tg mice.
