This study found that in keratin 14-targeted transgenic mice, BMP antagonism via noggin led to the development of hair follicle tumors, mediated through alterations in Wnt and Shh signaling pathways.

This study reveals an antagonistic competition between BMP and Wnt signaling within stem cells, influencing their fate towards hair germ characteristics based on the BMP/Wnt activity ratio.

This study found that ILK deficiency disrupts hair follicle development by impairing cell polarity and laminin-511 assembly, but these defects can be partially reversed with exogenous laminin-511.

This review discusses recent advances in understanding the molecular landscape of the dermal papilla, particularly focusing on Blimp1's role in hair follicle development and potential therapeutic targets for hair regeneration, but presents no new clinical results.

This study found distinct differences in protein expression and wound healing pathways between Acomys cahirinus and Mus musculus, highlighting potential targets for reducing fibrotic response in mammals.

This study found that overexpression of sFRP4 in skin cells reduces Wnt signaling activation, leading to decreased melanocyte differentiation in regenerating hair follicles.

This study found that lncRNA-599547 positively regulates the expression of the Wnt10b gene by interacting with miR-15b-5p, enhancing the inductive property of dermal papilla cells in cashmere goats.

This study found that the ethyl acetate extract of Fagraea berteroana fruits and its fraction FEAE-F0 promoted cell proliferation and modulated gene expression in hair follicle cells, suggesting potential for hair growth stimulation.

This review examines the origins and mechanisms of tumor initiation in common skin cancers, but does not present new experimental findings; it emphasizes the need for further research on cancer stem cells.

This study found that Ishophloroglucin A from brown seaweed may treat androgenic alopecia by inhibiting 5α-reductase and promoting hair growth-related factors in human dermal papilla cells.

In this study, exosomes derived from Iris germanica L. rhizomes (Iris-exosomes) were reported to alleviate oxidative stress and improve mitochondrial function in human follicle dermal papilla cells by activating the Wnt/β-catenin signaling pathway, suggesting potential benefits for hair loss treatment.

This review article examines recent studies on the role of diverse immune cells in forming an active niche for hair follicles, offering new insights into hair growth and related diseases.

This study suggests that hepatocyte growth factor (HGF) may play a role in hair follicle neogenesis and that an HGF mimetic could enhance skin substitute development.

This review discusses the role of BMP/Wnt signaling in regulating stem cell homeostasis and activation but reports no new experimental findings.

ANp63 is crucial for skin integrity, new filaggrin gene mutations link to eczema, hair can regrow from non-stem cells, sunburns are increasing, and glucocorticoids help treat skin allergies by affecting immune cells.

This study found that arrector pili muscles formed by Sonic Hedgehog signaling play a critical role in maintaining sympathetic nerve connections to hair follicle stem cells, influencing hair regeneration, with implications for hair loss treatments.

In this study, compound glycyrrhizin promoted hair regrowth in a testosterone-induced alopecia mouse model and increased human hair dermal papilla cell proliferation, likely through activating the Wnt/β-catenin pathway.

This study demonstrated that combining the Wnt/β-catenin activator CHIR99021 with 3D spheroid culture effectively enriched hair follicle formation in reconstituted human skin.

In this study, researchers found that WNT activation influenced FGF expression in human scalp-derived fibroblasts, with mouse model results showing FGF9 increased hair follicle number and diameter, while FGF7 reduced diameter.

This study found that 5-bromo-3,4-dihydroxybenzaldehyde (BDB) promoted hair growth in rat vibrissa follicles by activating Wnt/β-catenin and autophagy pathways and inhibiting the TGF-β pathway in dermal papilla cells.
