Epithelial stem cells can adapt and help in tissue repair and regeneration.

Skin cells called dermal fibroblasts are important for skin growth, hair growth, and wound healing.

Retinoic acid-binding proteins in skin are regulated by β-catenin and Notch signalling.

Hair thinning causes stem cell loss through a process involving Piezo1, calcium, and TNF-α.

Skin cells show flexibility in healing wounds and forming tumors, with potential for treating hair disorders and chronic ulcers.

Overexpressing Merkel cell virus proteins in human hair follicles can create clusters of cells that resemble Merkel cell cancer.

High levels of ERK activity are key for tissue regeneration in spiny mice, and activating ERK can potentially redirect scar-forming healing towards regenerative healing in mammals.

Fibroblasts are crucial for tissue repair and inflammation, and understanding them can help treat fibrotic diseases.

YAP and TAZ are crucial for skin cell growth and repair.

Epidermal Wnt/β-catenin signaling controls fat cell formation and hair growth.

TGFβ signaling prevents sebaceous gland cells from producing fats.

BMP signaling is essential for the development of touch domes.

Overactivating Hedgehog signaling makes hair follicle cells in mice grow hair faster and create more follicles.

Follistatin and LIN28B together improve the ability of inner ear cells in mice to regenerate into hearing cells.

Activin A and follistatin control when hair cells develop in mouse ears.

The Bcl-2 protein is important for keeping hair follicle stem cells working and preventing hair loss.

Different genes are active in dogs' hair growth and skin, similar to humans, which helps understand dog skin and hair diseases and can relate to human conditions.

New research shows that skin diversity is influenced by different types of dermal fibroblasts and their development, especially involving the Wnt/β-catenin pathway.

WWOX deficiency in mice causes skin and fat tissue problems due to disrupted cell survival signals.

Overactive Wnt signaling in mouse skin stem cells causes acne-like cysts and shrinking oil glands, which some treatments can partially fix.

Ultrasound can help deliver genes to cells to stimulate tissue regeneration and enhance hair growth, but more research is needed to perfect the method.

Retinoic acid helps activate hair growth in people with common hair loss by working on a specific cell growth pathway.

Activin A and follistatin control when ear hair cells form in mice.

Activin A promotes ear hair cell development, while follistatin delays it.

JAM-A helps hair regrowth in alopecia areata by protecting VCAN in skin cells.

The JAK/STAT pathway is important in cell processes and disease, and JAK inhibitors are promising for treating related conditions.

Activating c-Myc in skin causes rapid cell growth and changes, but these effects are reversible.

Skin stem cells interacting with their environment is crucial for maintaining and regenerating skin and hair, and understanding this can help develop new treatments for skin and hair disorders.

Hydrogel scaffolds can help wounds heal better and grow hair.

Notch signalling helps skin cells differentiate and prevents tumors.
