Early and late matrix progenitors in hair follicles create different cell layers, with early ones forming the companion layer and later ones forming the inner root sheath and hair shaft.

Understanding tooth development pathways may help regenerate teeth and treat dental issues.

Adhesion molecules are crucial for the development of feathers and hair.

Scientists successfully grew mini hair follicles using human skin cells, which could help treat baldness.

Skin stem cells in hair follicles are important for touch sensation.

Epidermal stem cells create and maintain skin structures like hair and nails through specific signaling pathways and vary by location and function.

Environmental cues can change the fate and function of epithelial cells, with potential for cell therapy.

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

Hox genes are crucial for development and tissue maintenance, affecting structures and functions throughout life.

Hox genes control hair follicle stem cell regeneration in different body regions.

The skin protects the body and is constantly renewed by stem cells; disruptions can lead to cancer.

Meis2 is essential for whisker development, independent of nerve involvement.

Specific proteins and molecules play key roles in the development of human hair follicles.

One type of progenitor cell can maintain normal skin in mice.

Several genes, including Hox-7A, Stra6, and Lim-1, are involved in normal palate formation.

Reptile skin hardens by layering beta-proteins on keratin.

Sonic hedgehog signaling is needed for the development of touch-receptor cells in the skin, and the loss of Polycomb repressive complex 2 can lead to more of these cells.

Egfl6 is not needed for zebrafish face development.

Hox proteins help maintain keratinocyte identity by regulating miRNA expression.

The study found that mouse sweat glands develop before birth, mature after birth, and have specific keratin patterns.

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

The cornified envelope is crucial for skin's barrier function and involves key proteins and genetic factors.

Secreted inhibitors of Wnt and IGF signaling control hair and tooth development, creating species-specific patterns.

Whiskers can form without sensory nerves or Foxd1, thanks to Meis2 in mesenchymal cells.

Keratin expression reflects cell organization and differentiation, not causes it.

A new 3D culture system helps grow and study mouse skin stem cells for a long time.
