Spiny mice are better at regenerating hair after injury than laboratory mice and could help us understand how to improve human skin repair.

Rodent spiny hair traits are due to genetic factors other than the Edar gene.

African spiny mice can regenerate skin and hair after wounds due to specific tissue mechanics.

Marsupial hair structure and keratin distribution are similar to placental mammals.

Mouse tail skin has different keratinization near hair follicles and scales.

Monotreme hair structure and protein distribution are similar to other mammals, but their inner root sheath cornifies differently, suggesting a unique evolution from reptile skin.

The big-clawed shrew's sinus hair follicles are highly specialized for sensing vibrations.

Hoxc13 and hair keratin are needed for forming rough skin on frog mating pads.

Trichostasis spinulosa mainly affects the nose, with many tiny hairs in one follicle, possibly influenced by hormones and sunlight.

Spiny mice can regenerate tissues instead of forming scars.

Capitate trichomes have more endoplasmic reticulum and vacuoles, while peltate trichomes have more plastids and larger subcuticular spaces.

The silver marmoset's skin is thin, lacks pigment cells, and has unique features like keratinized spines and specialized glands.

Trichostasis spinulosa is a rare skin condition with hair-filled plugs in hair follicles.

Lizard claws have hair-like keratins similar to those in mammals.

Trichohyalin-like proteins are essential for the development of skin structures like hair, nails, and feathers.

Corneous beta-proteins evolved uniquely in reptiles and birds, forming scales, claws, beaks, and feathers.

Antler velvet hair and body hair of red deer have different structures that help with protection and insulation.

Early tetrapod keratins evolved into toe pad proteins in amphibians and hair proteins in mammals.

Hair casts and cutaneous spicules can be signs of multiple myeloma.

Transplanted whisker follicles caused hair growth on the spine of mice.

Rat vibrissae have sensory terminals with specific structures that help detect hair movements.

The protein structures in the hair and tendon were preserved, but their molecular arrangements changed.

Hair keratins evolved from ancient proteins, diversifying through gene changes, crucial for forming claws and later hair in mammals.

Methylene blue staining effectively reveals detailed nerve structures in rat snouts.

The skin systems of jawed vertebrates evolved diverse appendages like hair and scales from a common structure over 420 million years ago.

Keratinous tissues have multiple structural layers, including ordered keratin and lipid granules.
