Hair follicle development in cashmere goats involves dynamic changes in proteins and metabolites, with key roles for oxytocin, MAPK, and Ca2+ pathways.

Hair follicle stem cells can form both hair follicles and skin.

β-catenin in the dermal papilla is crucial for normal hair growth and repair.

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

Activating the Wnt/β-catenin pathway could lead to new hair loss treatments.

Drosha and Dicer are essential for hair follicle health and preventing DNA damage in skin cells.

Researchers developed a quick and easy way to get and grow cells from the base of human hair follicles.

Cells in hair follicles help create fat cells in the skin by releasing a protein called Sonic Hedgehog.

The 190-kbp domain contains all human type I hair keratin genes, showing their organization and evolution.

mTOR signaling helps activate hair stem cells by balancing out the suppression caused by BMP during hair growth.

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

Inactive hair follicle stem cells help prevent skin cancer.

Notch signaling is essential for healthy skin and hair follicle maintenance.

Most hair follicle stem cells do not protect their DNA by dividing it unevenly.

Smad-4 and Smad-7 are key in hair follicle development, with other Smads being less important.

Disrupting Stat3 in hair follicle stem cells greatly reduces skin tumor formation.

Stem cells, especially from fat tissue and Wharton's jelly, can potentially regenerate hair follicles and treat hair loss, but more research is needed to perfect the treatment.

TGF-β2 plays a key role in human hair growth and development.

Hair growth is influenced by various body and external factors, and neighboring hairs communicate to synchronize regeneration.

MicroRNAs play a crucial role in skin and hair health, affecting everything from growth to aging, and could potentially be used in treating skin diseases.

Bone marrow and umbilical cord stem cells can help grow new hair.

Red ginseng oil and its components help promote hair regrowth and could treat hair loss.

Vitamin D3 can help improve hair growth by enhancing the function of specific skin cells and could be useful in hair regeneration treatments.

Human placenta hydrogel helps restore cells needed for hair growth.

Both immature and mature fat cells are important for hair growth cycles, with immature cells promoting growth and mature cells possibly inhibiting it.

Further research is needed to improve hair regeneration using stem cells and nanomaterials.

Dermal papillae cells, important for hair growth, come from multiple cell lines and can be formed by skin cells, regardless of their origin or hair cycle phase. These cells rarely divide, but their ability to shape tissue may contribute to their efficiency in inducing hair growth.

Merkel cells may have roles in sensing magnetic fields, creating fingerprints, Reiki energy healing, passing on environmental information to offspring, and influencing hair shape.

Modified stem cells from umbilical cord blood can make hair grow faster.

miR-140-5p in certain cell vesicles helps hair growth by boosting cell proliferation.
