This study found that proper levels of retinoic acid, controlled by the enzyme Cyp26b1, are essential for normal hair follicle development and morphogenesis in mice.

New mutations in hair keratin genes cause the rare hair disorder monilethrix.

This review discusses the history and challenges of hair follicle regeneration using follicular fragments and dissociated cells, without presenting new clinical results.

This study suggests that targeting the tumor stroma to promote the formation of dermal condensates may offer a novel approach to treating basal cell carcinoma.

This review discusses the essential roles and complex regulation of PP2A in various physiological processes and reports no clinical results; the authors highlight the need for further mouse model research to explore PP2A's therapeutic potential.

This review discusses recent advances in understanding hair follicle stem cell dynamics and interactions, but it reports no new experimental findings.

This study observed that using a relaxed suture technique on scalp incisions may prevent linear scars by reducing pressure on upper stem cells.

This case report presented a 52-year-old man with cutaneous focal mucinosis, exhibiting rare follicular induction of the epidermis, underscoring the importance of recognizing this association in differential diagnoses.

This study developed a 3D engineered hair follicle model that mimics the native hair bulb and may aid in drug screening for hair growth therapies.

In this study, researchers found that the number of dermal papilla cells in hair follicles determines hair size and shape in mice, suggesting potential avenues for addressing hair loss.

This study suggests that follicular stem cells in the bulge region are not directly targeted in androgenetic alopecia, based on the consistent presence of cytokeratin 15 across scalp samples from affected patients.

In this animal study, topical minoxidil shortened the telogen phase of hair growth cycles in rats, suggesting it may stimulate certain follicles to progress more rapidly to anagen.

This review discusses the generation of germ cell-like cells from skin-derived stem cells and reports no new results; the potential for these cells to produce viable progeny remains unclear.

This study describes a simplified method for isolating and cultivating human hair follicle papillae that can be easily executed by new lab personnel.

Non-thermal plasma helps hair grow by improving the area around hair follicles.

This study demonstrated that bioengineered hair follicles reconstituted from embryonic skin cells and transplanted into hosts can restore physiological hair functions, suggesting potential applications for treating alopecia.

This review discusses various approaches to treating alopecia, including drug therapy and hair transplantation, but reports no new research findings; the authors highlight the need for novel techniques like cell culturing.

In this study, daily topical minoxidil treatment in neonatal hairless pups led to increased hair growth and the development of hair follicles in the treated areas.

The document concluded that stem cells are crucial for skin repair, regeneration, and may help in developing advanced skin substitutes.

This review discusses the shedding phase of the hair cycle, known as exogen, and reports no new findings while analyzing related processes like club fiber formation and release.

This study found distinct differences in UEA I glycoprotein binding on follicular keratinocytes between anagen and telogen hair follicles, with staining associated with follicle length and regrowth.

This study found that overexpression of R-spondin 3 in a mice model impaired hair morphogenesis and regeneration by reducing hair matrix progenitor cell proliferation, thus disrupting the Wnt pathway's regulation of stem cells.

This study found that brain-derived neurotrophic factor (BDNF) inhibited hair shaft elongation and induced premature catagen development in cultured human hair follicles, partially through transforming growth factor β2.

The document explains how hair follicles develop, their structure, and how they grow.

In this study, researchers showed that Wnt ligands secreted by hair follicle epithelium are crucial for hair follicle regeneration and may be significant for treating hair disorders like alopecia.

Hair color production is closely linked to the active growth phase of hair in mice and may also influence hair growth itself.

This study found that intradermal adipocyte lineage cells in mice are necessary and sufficient to activate follicular stem cells, highlighting their role in regulating skin stem cell activity.

This study found that in mice, inactivating beta-catenin in the dermal papilla reduces hair follicle progenitor proliferation and disrupts the hair cycle.

This review discusses common hair loss conditions and explores how advancements in hair follicle biology might lead to more effective treatments but reports no new results.

This study found that downregulation of EGF and KGF signaling is necessary for hair follicle initiation in placodes, revealing a new role for KGF in hair follicle formation in mice.
