Keratin biomaterials from human hair help nerve regeneration by activating Schwann cells.

The research identified two types of keratinocytes in chicken scales: one for hard scales and another for soft skin, with similarities to human skin differentiation.

The research maps the complex development of early mouse skin, identifying diverse cell types and their roles in forming skin layers and structures.

Stem cells in eccrine glands could be used for regenerative medicine.

The hair follicle structure is more complex than thought, with new findings on protein formation.

Hair medullary cells in mammals vary in complexity, with humans having more structured cells similar to inner root sheath cells.

Developing hair follicles form from ring-shaped patterns, with future stem cells originating from the outer ring, not the upper layers, as previously thought.

A wide range of proteins are integrated into the skin's protective layer.

Higher levels of nidogen1 and type IV collagen are found in basal cell carcinoma compared to normal skin.

The skin's outer layer relies on lipids and proteins to protect against damage.

Keratinized wool cells still have some organelles like lysosomes and mitochondria.

Langerhans cells and melanocytes migrate to the skin and hair follicles during early human development.

LGR5 mainly stays inside cells, moving to the trans-Golgi network, and this process is important for its role in cell signaling.

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