Different signals work together to change gene activity and guide hair follicle stem cells to become specific cell types.

Hair follicle stem cells are controlled by their surrounding environment.

Certain RNA molecules are important for the development of wool follicles in sheep.

Stem cells can help other stem cells by producing supportive factors.

New hair follicles could be created to treat hair loss.

Bmpr2 and Acvr2a receptors are crucial for hair retention and color.

Human nails and hair follicles have similar gene activity, especially in the cells that contribute to their growth and development.

Synthetic ceramides may help hair growth by boosting cell growth in hair follicles.

Androgens reduce BMP2, which weakens the ability of certain cells to help hair stem cells become different types of cells.

The skin systems of jawed vertebrates evolved diverse appendages like hair and scales from a common structure over 420 million years ago.

The research identifies genes linked to wool quality in sheep and provides insights to improve wool production.

New treatments using stem cells and other methods show promise for promoting hair growth in androgenetic alopecia.

Overexpressing follistatin in mice delays wound healing and reduces scar size.

Vitamin B6 helps increase hair growth and density in rabbits by affecting certain cell signaling pathways.

Researchers created rat liver stem cells that could help repair liver failure in rats and may be useful for studying human liver diseases.

Hair loss in balding individuals is linked to changes in specific hair growth-related genes.

Genes related to keratin, skin cell differentiation, and immune functions are key in hedgehog skin and spine development.

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.

The document concludes that the hair cycle is a complex process involving growth, regression, and rest phases, regulated by various molecular signals.

Epithelial-mesenchymal interactions control hair growth cycles through specific molecular signals.

The document concludes that the hair cycle is a complex process involving growth, regression, and rest phases, regulated by various molecular signals.

Mutant mice help researchers understand hair growth and related genetic factors.

EGF and KGF signalling prevent hair follicle formation and promote skin cell development in mice.

Skin fat has important roles in hair growth, skin repair, immune defense, and aging, and could be targeted for skin and hair treatments.

Brg1 is crucial for hair growth and skin repair by maintaining stem cells and promoting regeneration.

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

Heparan sulfate is important for hair growth, preventing new hair formation in mature skin, and controlling oil gland development.

The BMP2 gene is more active in the early growth phase of Cashmere goat hair and may affect hair regeneration and textile production.

Bald thigh syndrome in sighthounds is caused by structural defects in hair shafts due to downregulated genes and proteins.

Genetically modified sheep with more β-catenin grew more wool without changing the wool's length or thickness.
