Trichohyalin helps in hair and skin cell structure and function by binding calcium and linking proteins.

Interleukin-1 increases keratin K6 production in skin cells.

Epidermal stem cells don't use gap junctions to communicate.

aPKCλ is crucial for keeping hair follicle stem cells inactive and maintaining normal hair growth.

Scientists now better understand how human hair growth is controlled, including the roles of specific genes and proteins.

A protein called sFRP4 from skin cells stops the development of pigment-producing cells in hair.

A specific group of slow-growing stem cells marked by Thy1 is crucial for skin maintenance and healing in mice.

Desmosomal adhesion is essential for healthy skin structure and function.

Low humidity changes skin gene expression, but emollients can help manage these changes.

GRK2 is essential for healthy hair follicle function, and its absence can lead to hair loss and cysts.

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

A gene mutation in mice causes skin defects and early death.

Human cathepsin V can replace mouse cathepsin L to maintain normal skin and hair in mice.

COX-2 levels change during the hair cycle and affect skin and hair growth.

ELL is crucial for gene transcription related to skin cell growth.

A more sensitive assay was developed to detect enzyme activity converting arginine to citrulline in hair follicles.

p120-catenin helps control skin inflammation by regulating cadherin levels.

Dsg1 is essential for maintaining a healthy skin barrier in mice.

Desmosomes are crucial for skin and heart development, and JNK may help regulate them.

Hair can regrow in adult mice's skin after injury, and this process can be boosted by increasing Wnt7a, a protein. This could potentially help treat baldness and change our understanding of hair growth.

Hair can regrow in adult mice's skin after injury, and this regrowth doesn't come from existing hair cells but from skin cells in the wound, with Wnt7a protein helping this process. This could help treat baldness and scarring.

Keratin is crucial for skin barrier formation and affects mitochondrial function.

Vertebrate skin evolved to be more specialized and complex, especially in land animals.

Cathepsin L deficiency causes hair and skin issues in mice.

Mutant MK6a transgenes in mice cause blistering, hair loss, and potential human alopecia.

Keratinocytes from dog hair follicles can create a functional skin layer in a lab model, useful for dog skin therapy.

Myc activation reduces skin stem cells by affecting cell adhesion.

Rac1 is vital for hair follicle health but not needed for skin maintenance.

Balanced protease activity is crucial for healthy skin and hair development.

HDAC1 is crucial for skin development and preventing tumors.
