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

Skin's Regulatory T cells are crucial for maintaining skin health and could be targeted to treat immune-related skin diseases and cancer.

RANK-RANKL signaling is essential for hair growth and skin health.

Special immune cells called Regulatory T cells help control skin inflammation and repair in various skin diseases.

iNKT cells can help prevent and treat alopecia areata by promoting hair regrowth.

Using defensins to activate stem cells may improve skin aging signs without causing inflammation.

Inflammation plays a key role in activating skin stem cells for hair growth and wound healing, but more research is needed to understand how it directs cell behavior.

Stem cells can help regenerate hair follicles.

Umbilical cord cells safely improve healing in long-term nonhealing wounds better than a placebo.

Red light at 627 nm can safely trigger IL-4 release in skin cells, potentially helping treat inflammatory skin conditions.

Using fat-derived stem cells with the drug meglumine antimoniate can help control skin disease and reduce parasites in mice with leishmaniasis.

Stem cells help remove dead cells to keep tissues healthy by balancing cell replacement and clearance.

Topical treatments can deliver active molecules to skin stem cells, potentially helping treat skin and hair disorders, including skin cancers and hair loss.

Anti-IL-12/IL-23 antibody therapy effectively treats psoriasiform skin lesions in IBD patients.

Periodontal ligament stem cells show promise for regrowing tissues but require more research for safe, effective use.

Keratinocytes and adipose-derived stem cells can effectively heal difficult skin wounds.

Hormones and neuroendocrine factors control hair growth and color, and more research could lead to new hair treatment options.

A substance called Vascular Endothelial Growth Factor can protect certain hair follicle stem cells from damage caused by androgens, suggesting a new possible treatment for hair loss.

Hair loss in mice starts with immune cells damaging hair roots before it becomes visible.

New treatments for vitiligo may focus on protecting melanocyte stem cells from stress and targeting specific pathways involved in the condition.

Immune cells are crucial for hair growth and preventing hair loss.

The research found that different types of fibroblasts are involved in wound healing and that some blood cells can turn into fat cells during this process.

Hair follicle development and microbes help regulatory T cells gather in newborn skin.

Macrophages help heal nerves by aiding the maturation of Schwann cells and are important for nerve repair.

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.

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

Lymphocytes, especially CD8+ T cells, play a key role in causing alopecia areata, and targeting them may lead to new treatments.

Fat cells are important for tissue repair and stem cell support in various body parts.

New treatments targeting skin stem cells show promise for skin repair, anti-aging, and cancer therapy.

Skin and hair can help us understand organ regeneration, especially how certain stem cells might be used to form new organs.
