Scientists created a new cell line from Cashmere goat hair and found that cytokeratin 13 is a unique marker for certain skin cells.

Two mouse mutants have defective hair cuticle cross-linking.

Hair follicle stem cells are crucial for touch sensation and proper nerve structure in mice.

Keratinization in embryos helped vertebrates adapt to land by forming a protective skin barrier.

Early shedding of the inner root sheath in noninflamed hair follicles is a relatively specific sign of Central Centrifugal Cicatricial Alopecia.

The conclusion is that new methods for isolating hair cuticle cells and removing the cuticle layer are effective and convenient.

The 4C32 gene may help in mouse skin development and differentiation.

Dermal sheath cells help heal wounds by showing both skin and connective tissue traits.

Lipase H is important for hair follicle function and shaping hair fibers.

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

Basal-cell epitheliomas and the pilosebaceous tract share a unique keratin, distinguishing them from other skin areas.

The dermal sheath's contraction is crucial for hair follicle regression and stem cell relocation.

Pubic hair has a thicker, more protective outer layer than scalp hair, possibly due to evolution.

Merkel cells are abundant in facial vellus hair follicles, especially during the anagen phase.

Aging reduces dermal sheath cells, affecting youthful skin appearance.

cDermo-1 causes dense skin, feathers, and scales in chickens.

Without keratin 10, there's more growth and development of oil-producing skin cells.

Cell movements and forces shape feather growth in chicken skin.

Deleting the Hoxc13 gene in frogs shows its crucial role in developing skin structures similar to hair.

Yuyi hairless mice lose hair after birth, develop thick, loose skin with folds, and show disorganized skin structure as they age.

Pangolins have lost some skin-related genes, but kept others, leading to their unique scales and skin features.

CDP is crucial for lung and hair follicle cell development.

Reptile skin protects and prevents water loss, helping them adapt to land.

A specific protein in chicken embryos links early skin layers to feather development.

Trichohyalin granules help inner root sheath cells in hair follicles harden by integrating with keratin filaments.

K25, K27, and K28 are found in all inner root sheath layers of hair, while K26 is only in the cuticle.

Reptilian scales, feathers, and hairs evolved from changes in skin cell interactions.
