Hair color production in mice is closely linked to the hair growth phase and may also influence hair growth itself.

Hair follicle stem cells are key for hair and skin regeneration, can be reprogrammed, and have potential therapeutic uses, but also carry a risk of cancer.

Latanoprost can make eyelashes longer, thicker, and darker.

Memory T cells in the skin balance staying put and moving into the blood, clustering around hair follicles, and increasing in number after infection.

Bioprinting could improve wound healing but needs more development to match real skin.

The document concludes that more research is needed to better understand and treat primary cicatricial alopecias, and suggests a possible reclassification based on molecular pathways.

Aging causes skin stem cells to work less effectively.

The niche environment controls stem cell behavior and plasticity, which is important for tissue health and repair.

TGF-β signaling is crucial for stem cell maintenance, differentiation, and has implications for cancer treatment.

The conclusion is that Treg-targeted therapies have potential, but more knowledge of Treg biology is needed for effective treatments, including for cancer.

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.

The skin's internal clock affects healing, cancer risk, aging, immunity, and hair growth, and disruptions can harm skin health.

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

TRP channels in the skin are important for sensation and health, and targeting them could help treat skin disorders.

Modern lifestyles, including poor diet, stress, and long-term use of certain medications, hinder the body's ability to heal from inflammation, leading to chronic diseases.

Macrophages help regrow hair by activating stem cells using AKT/β-catenin and TNF.

Hair color production is closely linked to the active growth phase of hair in mice and may also influence hair growth itself.

We need more research to better understand human hair follicle stem cells for improved treatments for hair loss and skin cancer.

Pure carbon nanotubes are safe for mice, but impure ones cause immune issues and hair loss.

Restoring hair bulb immune privilege is crucial for managing alopecia areata.

Prolactin affects hair growth and skin conditions, and could be a target for new skin disease treatments.

The document concludes that accurate diagnosis of different types of hair loss requires careful examination of hair and scalp tissue, considering both clinical and microscopic features.

BMP2 and BMP7 have opposite roles in feather formation.

The skin protects the body and is constantly renewed by stem cells; disruptions can lead to cancer.

Circadian rhythms are crucial for stem cell function and tissue repair, and understanding them may improve aging and regeneration treatments.

Hair follicle regeneration needs special conditions and young cells.

Targeting the skin's endocannabinoid system could help treat skin disorders.

Zinc deficiency in children can cause skin issues and can be serious if not diagnosed and treated properly.

S100A4 and S100A6 proteins may activate stem cells for hair follicle regeneration and could be potential targets for hair loss treatments.

Keratin proteins are crucial for healthy skin, but mutations can cause skin disorders with no effective treatments yet.
