The nucleus is key in controlling skin growth and repair by coordinating signals, gene regulators, and epigenetic changes.

Certain factors can start hair growth in adult skin by making cells communicate and form new hair follicles.

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.

Lgr5 is a marker for active, long-lasting stem cells in mouse hair follicles.

Different types of long-lasting stem cells are responsible for the growth and upkeep of the mammary gland.

Melatonin affects many body functions beyond sleep by interacting with specific receptors in various tissues.

β-catenin is essential for stem cell activation and proliferation in hair follicles.

Auxin and ethylene hormones both work together and against each other to control plant growth.

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

Calreticulin has roles in healing, immune response, and disease beyond its known functions in the endoplasmic reticulum.

Air pollution worsens skin diseases and aging by causing inflammation and oxidative stress.

The circadian clock affects skin stem cell behavior, impacting aging and cancer risk.

Lichen Planus is a less common condition affecting skin and mucous membranes, with various types and associated risk factors, challenging to diagnose, significantly impacts life quality, and may have a risk of cancerous changes in oral lesions.

TRPA1 is crucial for mechanical sensitivity in skin sensory neurons.

Wnt signaling is crucial for pigmented hair regeneration by controlling stem cell activation and differentiation.

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

Tofacitinib is safe and effective for severe alopecia areata, but hair loss may return 2 months after stopping treatment.

Noggin is necessary to start the hair growth phase in skin after birth.

Blocking JAK-STAT signaling can lead to hair growth.

Memory regulatory T cells need IL-7, not IL-2, to stay in peripheral tissues.

MIM is crucial for hair follicle formation and regeneration by controlling cilia formation and hedgehog signaling through its interaction with Cortactin and Src.

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

PDGFA/AKT signaling is important for the growth and maintenance of certain skin fat cells.

Correct skin biopsy techniques are crucial to avoid misdiagnosis of skin diseases.

New single-cell analysis techniques are improving our understanding of stem cells and could help in treating diseases.

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

Nerves and chemicals in the body can affect hair growth and loss.

Thymosin β4 promotes hair growth by activating stem cells in hair follicles.

Newborn mouse skin cells can grow hair and this process can be recreated in adult cells to potentially help with hair loss.

Wnt signaling helps control how brain stem cells divide and is important for brain repair after injury.
