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.

Genetically-altered adult stem cells can help in wound healing and are becoming crucial in regenerative medicine and drug design.

Statins may be linked to reproductive organ conditions, and their risks should be monitored.

Activating a protein called β-catenin in adult skin can make it behave like young skin, potentially helping with skin aging and hair loss.

The pituitary gland functions normally even after losing most SOX2+ stem cells.

Lipocalin-Type Prostaglandin D2 Synthase (L-PGDS) is a protein that plays many roles in the body, including sleep regulation, pain management, food intake, and protection against harmful substances. It also affects fat metabolism, glucose intolerance, cell maturation, and is involved in various diseases like diabetes, cancer, and arthritis. It can influence sex organ development and embryonic cell differentiation, and its levels can be used as a diagnostic marker for certain conditions.

Researchers isolated a new type of stem cell from mouse skin that can renew itself and turn into multiple cell types.

Vitamin D3 may protect rat hair follicles from radiation damage.

Hair loss in Androgenetic alopecia (AGA) is due to altered cell sensitivity to hormones, not increased hormone levels. Hair growth periods shorten over time, causing hair to become thinner and shorter. This is linked to miscommunication between cell pathways in hair follicles. There's also a change in gene expression related to blood vessels and cell growth in balding hair follicles. The exact molecular causes of AGA are still unclear.

Using protein degradation to fight cancer drug resistance shows promise but needs more precise targeting and fewer side effects.

Researchers created a model to understand heart aging, highlighting key genes and pathways, and suggesting miR-208a as a potential heart attack biomarker.

Different types of stem cells in hair follicles play unique roles in wound healing and hair growth, with some stem cells not originating from existing hair follicles but from non-hair follicle cells. WNT signaling and the Lhx2 factor are key in creating new hair follicles.

Caspases are enzymes important for both cell death and various non-lethal cell functions, affecting head development and hair growth, with different caspases playing specific roles.

The Brazilian Society of Dermatology agrees that oral isotretinoin is effective for acne and other skin conditions, and it's safe when monitored, but more research is needed on dosing and duration.

The research found specific genes that may cause longer hair in Tianzhu White Yak.

Hydrogel microcapsules help create cells that boost hair growth.

Twist1 helps maintain important features of cells crucial for hair growth by working with Tcf4 and β-catenin.

The PP2A-B55α protein is essential for brain and skin development in embryos.

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

FGF5 spliceosomes inhibit rabbit hair growth by affecting gene expression.

Cancer can hijack the body's cell repair system to promote tumor growth, and targeting this process may improve cancer treatments.

Botryococcus terribilis and its compounds may promote hair growth and improve hair health.

Marine-derived saccharides may help reduce aging effects on skin and hair by promoting cell growth and collagen production.

Topical drugs and near-infrared light therapy show potential for treating alopecia.

Low-level laser treatment helps mice grow hair by increasing certain protein levels linked to hair growth.

Microparticles help caffeic acid stay longer in hair follicles for better treatment of folliculitis.

Ruby laser pulses best destroy hair follicles during the growth phase and effectiveness varies with laser intensity; melanin is key for targeting, and timing treatments can improve results.

Arabica coffee pulp extract may help prevent hair loss and promote hair growth.

Understanding keratinization is crucial for treating skin conditions like ichthyoses and psoriasis.

Trichoscopy is useful for diagnosing and monitoring systemic lupus erythematosus, with certain hair and scalp changes indicating more active disease.
