The conclusion is that the nuclear lamina and LINC complex in skin cells respond to mechanical signals, affecting gene expression and cell differentiation, which is important for skin health and can impact skin diseases.

Skin cells produce and activate vitamin D, which regulates skin functions and supports hair growth.

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

RXRα is crucial for hair growth and skin cell function.

Overexpression of COX-2 in mice skin causes abnormal skin and hair development.

Outer root sheath cells consistently express certain keratins influenced by their environment.

Cytokeratin 19 and cytokeratin 15 are key markers for monitoring the quality and self-renewing potential of engineered skin.

Increased 11β-HSD1 activity in skin may contribute to aging and could be targeted to reduce aging effects.

Scientists turned mouse stem cells into skin cells that can grow into skin layers and structures.

Notch1 helps skin heal by attracting specific immune cells.

Hard skin features like scales, feathers, and hair evolved through specific protein changes in different animal groups.

Keratin 15 is not a reliable sole marker for identifying epidermal stem cells because it's found in various cell types.

Hairless protein can block vitamin D activation in skin cells.

Different keratin types have unique amino acid patterns that are evolutionarily conserved.

Psoriasis causes changes in certain keratins and shrinks sebaceous glands in the scalp.

CYP2B12 enzyme in skin cells converts arachidonic acid into specific bioactive lipids.

Type I keratin genes are closely linked to the rex locus on mouse chromosome 11, affecting hair development.

Keratin 15 cells from hair follicles help develop and maintain skin tumors in mice.

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

RXR-alpha is strongly expressed in both normal and psoriatic skin and may help in skin cell differentiation and hair growth.

GRHL3 is important for controlling gene activity in skin cells during different stages of their development.

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

Skin and hair can regenerate after injury due to changes in gene activity, with potential links to how cancer spreads. Future research should focus on how new hair follicles form and the processes that trigger their creation.

Mutations in the p63 gene affect skin adhesion, barrier integrity, and hair growth.

The keratin 5 mutation in a family with epidermolysis bullosa simplex was due to mosaicism, not a new mutation.

Researchers created early-stage hair-like structures from skin cells, showing how these cells can self-organize, but more is needed for complete hair growth.

Nail-matrical fibroblasts can make non-nail cells produce hard keratin, useful for nail repair.

Skin stem cells are maintained by signals from nearby cells and vary in their ability to renew and mature.

The research found that chickenpox virus spreads in skin through blood then to skin cells, while shingles virus moves from nerves to hair follicle areas before infecting skin cells.

Thyroid hormones affect skin texture, hair and nail growth, and can cause skin diseases related to thyroid problems.
