Short telomeres contribute to aging and cancer, and while telomerase can delay aging, it may also promote cancer.

Mice without the vitamin D receptor have bone issues and other health problems, suggesting vitamin D is important for preventing various diseases in humans.

Hair growth and health are influenced by factors like age, environment, and nutrition, and are controlled by various molecular pathways. Red light can promote hair growth, and understanding these processes can help treat hair-related diseases.

FGF9 helps hair follicles grow in small-tailed Han sheep by affecting cell growth and certain signaling pathways.

Persistent radiation-induced hair loss is dose-dependent, and treatments like topical minoxidil can be effective.

Retinoic acid-binding proteins in skin are regulated by β-catenin and Notch signalling.

Lower SMAD2/3 activation predicts more severe skin cancer.

Printing human stem cells and a special matrix during surgery can help grow new skin and hair-like structures in rats.

Stem cells in the hair follicle are regulated by their surrounding environment, which is important for hair growth.

Human stem cells can help form hair follicles in mice.

The conclusion is that tissue structure is key for stem cell communication and maintaining healthy tissues.

Blocking TSLP reduces skin inflammation and cell overgrowth in psoriasis.

Using extracellular vesicles from stem cells can help hair grow by affecting scalp cells and hair follicles.

The conclusion is that teeth, hair, and claws have similar stem cell niches, which are important for growth and repair, and more research is needed on their regulation and potential markers.

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.

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

Melanocyte stem cells are crucial for skin pigmentation and have potential in disease modeling and regenerative medicine.

The TGF-β family helps control how cells change and move, affecting skin, hair, and organ development.

Dogs could be good models for studying human hair growth and hair loss.

K15 and Id3 are important in hair follicle regeneration, with K15 increasing in early stages and Id3 responding later.

Regenerative cellular therapies show promise for treating non-scarring hair loss but need more research.

Current methods can't fully recreate skin and its features, and more research is needed for clinical use.

Tooth papilla cells can help regenerate hair follicles and grow hair.

Epidermal stem cells have potential for personalized regenerative medicine but need careful handling to avoid cancer.

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

The "Two-Cell Assemblage" assay is a new, simple method to identify substances that may promote hair growth.

Androgens can both promote and prevent hair growth due to differences in gene expression in hair follicles.

The document concludes that treatments for cicatricial alopecia are not well-supported by evidence, but hair transplantation shows more predictable and satisfactory results.

Ganoderma lucidum extract may help treat stress-related hair loss.

The hair growth serum Trichosera® was effective in increasing hair regrowth and density and reducing hair fall without significant side effects.
