Different types of stem cells exist within individual skin layers, and they can adapt to damage, transplantation, or tumor growth. These cells are regulated by their environment and genetic factors. Tumor growth is driven by expanding, genetically altered cells, not long-lived mutant stem cells. There's evidence of cancer stem cells in skin tumors. Other cells, bacteria, and genetic factors help maintain balance and contribute to disease progression. A method for growing mini organs from single cells has been developed.

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.

Hair follicle stem cells from aged eyelid skin can become corneal endothelial-like cells for potential eye treatments.

Bacteria can help skin regenerate through a process called IL-1β signaling.

Stem cell plasticity is crucial for wound healing but can also contribute to cancer development.

Mutations in the SHH pathway in certain skin cells can cause skin tumors and abnormal hair growth.

Touch dome keratinocytes in adult skin have traits of different skin cell types.

Skin-derived precursors in hair follicles come from different origins but function similarly.

Environmental cues can change the fate and function of epithelial cells, with potential for cell therapy.

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

Inhibiting AP-1 changes skin tumor types and affects tumor cell identity.

Platinum nanozyme microneedles can effectively and safely promote hair growth for androgenetic alopecia.

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

Scientists created stem cells that can grow hair and skin.

Skin and hair renewal is maintained by both fast and slow cycling stem cells, with hair regrowth primarily driven by specific stem cells in the hair follicle bulge. These cells can also help heal wounds and potentially treat hair loss.

Understanding where cancer cells come from helps create better prevention and treatment methods.

Scientists identified a group of human skin cells with high growth and regeneration potential.

Ectomesenchyme is a key source of skin stem cells.

Blocking cell death in certain stem cells can improve wound healing and tissue regeneration.

Scientists found gene mutations that affect hair loss, skin stem cells, and skin disorders, and identified drugs that may help treat blood vessel and skin conditions.

Mammalian organs regenerate using stem cells and cell plasticity, but this ability declines with age.

Fibroblasts can be turned into melanocytes for potential skin treatments.

Deleting the BRD4 protein in certain skin cells causes hair loss and skin inflammation.

Skin health and repair depend on the signals between skin stem cells and their surrounding cells.

Lrig1 marks a unique group of stem cells in mouse skin that can become different skin cell types.

The research reveals how early embryonic mouse skin develops from simple to complex structures, identifying various cell types and their roles in this process.

Lrig1 marks a unique group of stem cells in mouse skin that can become different skin cell types.

Wnt/ß-catenin signaling is crucial for regulating skin stem cells and hair growth, with the right levels and timing needed for proper function.

UV exposure harms skin by causing fibroblast loss, but T cells help fibroblast survival.

Changing YBX1 protein activity affects skin stem cell function and aging.
