From horizontal axis, mane (a1–5), body (b1–5), tail (c1–5), fetlock (d1–5); from longitudinal axis, (a1-d1) and (a4-d4) are anatomical lens images under 2X amplification. (a2-d2), (a3-d3) and (a5-d5) are microscope images of transparency stain or HE stain. Scale bars are, respectively, 100 μm, 200 μm, and 500 μm, as shown in pictures. e is the comparison of hair follicle dermal papilla diameter; f is the comparison of hair follicle density
