This study found that hair follicle patterning in development may arise from a combination of epidermal prepattern signals and mesenchymal self-organisation, with fibroblast growth factor and bone morphogenetic protein activities playing key roles.

This review discusses the dynamic, niche-driven regulation of stem cell states in tissue homeostasis and regeneration, focusing on epithelial stem cells in the mammalian skin, intestine, and lung, without providing new experimental results.

This review examines the adaptive value and mechanisms of seasonal coat colour moulting in birds and mammals, highlighting the challenge of camouflage mismatch and the necessity for evolutionary adaptation under climate change.

This article reviews the history and impacts of direct-to-consumer advertising of prescription drugs in the U.S. and reports no new research findings; it discusses implications for health policy debates.

This study found that laminin-511 is crucial for hair morphogenesis in mice, as it influences primary cilia formation and dermal papilla maintenance through noggin and sonic hedgehog signaling.

This study found that a genetic variant in the EDAR gene leads to typical East Asian hair characteristics by increasing signaling output, as shown in transgenic mice experiments.

This study found that newborn mouse skin organoids can robustly grow hair in vivo, while adult organoids require specific interventions to restore their hair-forming ability.

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

This study found that follistatin and activin interactions are important for hair follicle development and cycling in mice, suggesting that they may regulate processes involving BMP-2 and its antagonist.

This study found that procyanidin oligomers, particularly dimers and trimers, significantly promoted hair growth in mice and hair epithelial cell cultures, suggesting potential use as hair growth agents.

This study found that overexpressing the BMP inhibitor Noggin in transgenic mice led to a significant loss of nontylotrich hair follicles, suggesting a critical role for BMP signaling in hair follicle morphogenesis and cycling.

This review discusses the multiple layers of environmental controls on hair stem cell homeostasis and suggests that targeting these layers could offer safer regenerative medicine therapies without directly using stem cells.

This article discusses the distribution of extracellular matrix molecules in human hair follicles and reports no new results.

This study found that Hoxc gene expression can reprogram mesenchymal dermal papilla cells, enhance epithelial stem cell regenerative potential, and promote region-specific hair follicle regeneration through Wnt signaling.

This study found that GLI2 plays a key role in activating follistatin, an activin/BMP antagonist, in response to hedgehog signaling in human epidermal cells, with implications for hair follicle development and basal cell carcinoma.

This study demonstrated that an engineered human skin equivalent can generate follicle-like structures resembling fetal skin, highlighting the role of the dermal compartment in directing epithelial cell fate in vitro.

This study found that measuring reproductive hormone levels in brown bear hair may effectively support non-invasive genetic sampling, though larger samples or more sensitive techniques are needed for broader application.

This study suggests that human keratin fiber matrix has a well-defined nano-scale grainy structure rather than being amorphous, with grain size influenced by chemical treatments, temperature, humidity, and follicle-level factors.

This review discusses the structure and regenerative potential of hair follicles, highlighting their role in wound healing, stem cell populations, and keratin-based biomaterials, but it reports no new clinical results.
