Live imaging has advanced our understanding of stem cell behavior and raised new research questions.

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.

Estrogen is important for keeping adult mouse nipple skin healthy by controlling certain cell signals.

Platelet-rich plasma and stem cell therapies are accepted treatments for hair restoration, with specific protocols recommended for best results, but more standardization is needed in stem cell use.

Wnt/beta-catenin signaling in the skin helps fat cell development during hair growth and repair.

Disrupting Smad4 in mouse skin causes early hair follicle stem cell activity that leads to their eventual depletion.

Minoxidil affects cell growth in two ways: low doses increase growth, while high doses slow it down and can be toxic.

EGF and FGF boost hair cell growth, hydrocortisone slows it, and minoxidil doesn't affect it.

Activating telomerase can boost hair follicle stem cell growth and hair production.

Houttuynia cordata extract may help hair grow by improving cell survival and increasing cell growth.

Overexpression of sPLA2-IIA in mouse skin reduces hair stem cells and increases cell differentiation through JNK/c-Jun pathway activation.

The study suggests that higher levels of SIRT1 and SIRT2 may improve overall cell health and aging processes.

Lgr5 is a marker for active, self-renewing stem cells in the intestine and skin, important for tissue maintenance.

Scientists have developed a new method to detect steroid abuse in athletes using cell-based tests, which could be the future of anti-doping methods.

Notch signalling helps skin cells differentiate and prevents tumors.

Epidermal stem cells maintain skin health through specific niches and signaling pathways.

Exosomes show promise for skin rejuvenation and anti-aging in cosmetic dermatology.

Activating cAMP and ATP improves hair growth and strength.

BLIMP1 is essential for skin maintenance but not for defining sebaceous gland progenitors.

Autophagy is important for human hair growth and health.

TNFα helps grow and maintain liver cells in 3D culture for a long time.

The document concludes that understanding the sebaceous gland's development and function is key to addressing related skin diseases and aging effects.

Sox2-positive dermal papilla cells have unique characteristics and contribute more to skin and hair follicle formation than Sox2-negative cells.

Vitamin D is important for bones, hair, blood pressure, and breast development.

Skin stem cells maintain and repair the outer layer of skin, with some types being essential for healing wounds.

Different types of fibroblasts play various roles in both healthy and diseased tissues, and understanding them better could improve treatments for fibrotic diseases.

Stem cells are key for the growth, upkeep, and repair of sebaceous glands and for understanding skin disorders.

Deleting Snai2 and Snai3 causes fatal autoimmunity.

Elaine Fuchs' research shows how skin stem cells maintain health, aid in healing, and are involved in cancer.

Higher fluence in hair removal damages hair follicles more, while lower fluence mimics natural hair regression, with long-term IPL treatments effectively reducing hair.
