A new method helps identify and classify different types of hair casts.
research Skin and hair regeneration after calciphylaxis. Histologic changes during formation and shedding of the calciphylactic carapace of the rat
After calciphylaxis, rats showed incomplete skin and hair regeneration, resembling scar tissue with fewer hairs.
research The structure of the cornified claw sheath in the domesticated cat (Felis catus): implications for the claw‐shedding mechanism and the evolution of cornified digital end organs
Cat claws stay sharp by shedding their outer layer through microcracks formed during activities.
research ‘Hard’ and ‘soft’ principles defining the structure, function and regulation of keratin intermediate filaments
Keratin filaments are crucial for cell structure and protection, with ongoing discoveries about their genes and functions.
research Trichothiodystrophy: an ultrastructural study of the hair follicle
Trichothiodystrophy causes abnormal protein deposits and distortion in hair follicles.
