Acomys spine morphology at first postnatal anagen phase . (A) Pan-Keratin (red), Laminin (green), and Hoechst (blue) immunostaining and (B) HEA coloration of a lower back hair; arrowhead, dermal papilla (DP); dashed arrows, sebaceous gland. (C) Detail of A showing the matrix (Mx) and DP. The dashed line indicates the tilted base of the follicle. (D) 3D-reconstructed follicle from 102 sections (see Supplementary Movie 1). (E) Detail of A; white frames: outer root sheath (ORS) and inner root sheath (IRS), double facing arrows: IRS cuticle (Cut). (F) Detail of B; black frames: ORS, IRS, and IRS Huxley’s layer (Hux), double facing arrows: Henle’s layer (Hen). (G) Scanning electron micrograph of a lower back adult awl hair fracture. The border between medulla (M) and cortex (C) is delineated with dashed line. Scale bars: 100 μm.
