Collagen VII helps skin heal and stay strong, sirolimus may lower skin cancer risk in kidney transplant patients, high-molecular-mass hyaluronan helps naked mole rats resist cancer, dermal γδ T cells aid in hair growth in rodents, and overexpression of IL-33 in mouse skin causes itchiness, offering a model for studying allergic inflammation treatments.

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.

Certain cells from hair follicles can create new hair and contribute to hair growth when implanted in mice.

Blocking β-catenin in skin cells improves hair growth during wound healing.

The nude gene causes skin cell overgrowth and improper development, leading to hair and urinary issues.

Mice healed without scars as fetuses but developed scars as adults, suggesting scarless healing might be replicated with further research.

Noncoding dsRNA boosts hair growth by activating TLR3 and increasing retinoic acid.

The vitamin D receptor is essential for skin stem cells to grow, move, and become different cell types needed for skin healing.

Live imaging has advanced our understanding of stem cell behavior and raised new research questions.

Laser and minoxidil combo promotes better hair growth than minoxidil alone, safely.

SCF and ET-1 together significantly increase skin pigmentation and melanin production.

Fat stem cells from diabetic mice can still help heal wounds.

Vitamin D and calcium are important for quick and effective skin wound healing.

Genetic mutation and carcinogen treatment are both needed for skin cancer to develop in these specific mice.

Eating selenium-rich rice improved antioxidant activity and signs of aging in mice.

Mice with too much sPLA₂-IIA have hair loss and poor wound healing due to abnormal hair growth and stem cell depletion.

Mongolian gerbils heal wounds differently than mice, with unique protein levels and gene expression that affect skin repair.

CD4+ skin cells may be precursors to basal cell carcinoma.

DNA methylation is essential for skin and hair follicle development, and could be a target for treating skin diseases.

The skin's dermal layer contains true stem cells with diverse functions and interactions that need more research to fully understand.

Cell death shapes skin stem cell environments, affecting inflammation, repair, and cancer.

Microneedle technology is effective for skin rejuvenation and enhancing cosmeceutical delivery, with ongoing innovation and increasing commercialization.

Astrotactin2 affects hair follicle orientation and skin cell polarity.

A specific mutation known for causing cancer is also found to cause a skin condition in a young girl.

Mast cells and VEGF contribute to post-surgery adhesions, and blocking VEGF can reduce these adhesions; also, certain factors affect wound healing and fetal skin heals differently with age.

Nerve signals are crucial for hair follicle stem cells to become skin stem cells and help in wound healing.

Hair growth phase and certain genes can speed up wound healing, while an inflammatory mediator can slow down new hair growth after a wound. Understanding these factors can improve tissue regeneration during wound healing.

Basal cell carcinoma mostly starts from cells in the upper skin layers, not hair follicle stem cells.

Growing human skin cells in a 3D environment can stimulate new hair growth.

Hair loss and aging are caused by the breakdown of a key protein in hair stem cells.
