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.

Rac1 is essential for proper hair structure and color.

Immune cells help keep skin healthy and repair it, but imbalance can cause disease.

New hair can grow from large wounds in mice, but less so as they age, involving reprogramming of skin cells and specific molecular pathways.

Different cell types work together to repair skin, and targeting them may improve healing and reduce scarring.

Olive leaf extract may help improve skin aging, especially for those who don't exercise regularly.

Polyamines are crucial for skin tumor development, and inhibiting them can prevent tumors.

Removing Lrig1-positive cells in mice leads to temporary loss of sebaceous glands.

Non-immune dermal cells dominate, epidermal cells increase after day 9, and certain immune cells persist beyond inflammation in wound-induced hair follicle regeneration.

Live imaging helps us understand skin immune responses and develop treatments.

Adult skin cells can be used to create new hair in a lab.

Injecting lab-grown hair cells into the scalp can regrow hair.

The Hairless gene is crucial for healthy skin and hair growth.

Hair follicles are complex, dynamic mini-organs that help us understand cell growth, death, migration, and differentiation, as well as tissue regeneration and tumor biology.

Ng2+ perivascular cells in mouse skin come from specific fibroblast types and help in tissue repair.

Revertant cell therapy shows promise for treating type XVII collagen deficiency, but better cell selection methods are needed.

iPSC-derived stem cells on a special membrane can help repair full-thickness skin defects.

Hair follicle stem cell research has advanced in understanding and using these cells for hair growth and skin repair.

A specific combination of chemicals effectively expands genetically modified skin cells for potential use in skin therapy.

Chrysanthemum zawadskii extract helps hair grow by stimulating hair cells.

Hair growth can be induced by transplanting certain cells, but these cells lose their properties during culturing. The best cell interaction happens in a liquid medium under gravity, and using collagen doesn't help. Future research could focus on using growth factors to stimulate these cells.

Hordenine may help hair grow by activating a specific cell growth pathway.

Brg1 is crucial for keeping hair follicle stem cells and repairing skin, working with the Sonic Hedgehog pathway to promote hair growth.

Scientists used a special imaging technique to observe that hair follicle regeneration involves cell division and structural changes, mostly in the lower part of the follicle, and that the dermal papilla at the base is crucial for regrowth.

Keratins are crucial for cell stability, wound healing, and cancer diagnosis.

Activating TERT in mice skin boosts hair growth by waking up hair follicle stem cells.

Alopecia areata is an autoimmune condition causing hair loss, influenced by genetics, stress, and diet, and may be prevented by a high soy oil diet.

EGFR is essential for normal hair development and follicle differentiation.

Restoring mitochondrial function in mice reversed their skin wrinkling and hair loss.

The biology of skin and hair is complex and not fully understood.
