This review explores the mechanism and potential applications of wound-induced hair follicle neogenesis but reports no new clinical results, highlighting the need for further research in hair regeneration therapies.

This study found that nestin-expressing unipotent progenitor cells capable of differentiating into outer root sheath keratinocytes are present during hair follicle development and in adult hair follicles.

This study revealed that nestin-expressing progenitor cells capable of becoming ORS keratinocytes are present during both hair follicle development and in adult hair follicles.

This study concluded that Wnt/β-catenin signaling, through Shh and Bmp pathways, is crucial for determining hair follicle fate in embryonic epidermal development.

This study found that a cocktail of three proteins from embryonic skin can enable adult fibroblasts to regenerate hair follicles by altering gene expression and activating regenerative signaling pathways.

In this study, Wnt-10b was found to promote hair follicle development and hair growth in cultured mouse embryonic skin and transplanted skin in nude mice.

This study found that human hair follicle-derived mesenchymal stem cells effectively maintained human embryonic stem cells in an undifferentiated state, comparable to mouse embryonic fibroblasts under standard conditions.

This study found that cultured hair follicle dermal cells support maintenance and potentially aid in the clinical application of pluripotent and haematopoietic stem cells.

This study in mice found that overexpressing Sonic Hedgehog in basal cells caused skin anomalies and a lack of certain hair fibers, underscoring its key role in hair follicle development.

In this study, researchers used proteomic and metabolomic analyses to explore hair follicle development in embryonic cashmere goats, identifying significant roles for the oxytocin signalling pathway and associated networks in this process.

This study reports that BMP2 expression in goat skin is higher during late telogen and early anagen phases, indicating a potential role in hair follicle regeneration.

This study found that activating β-catenin signaling in embryonic epidermis promoted hair follicle characteristics at the expense of normal epidermal differentiation, leading to early pigmentation and innervation.

This study characterizes gene expression patterns in embryonic hair follicle progenitors and their niche, identifying signaling pathways like axon guidance that may drive cellular rearrangements for hair follicle formation.

This study found that nestin-expressing progenitor cells, capable of becoming ORS keratinocytes, are present in both developing and adult mouse hair follicles.

This study observed that cell aggregates formed rapidly in cultures of rat hair follicle cells, with proteins showing hair cortical keratin but not synthesizing it as anticipated.

This study suggests that human and mouse hair follicle stem cells may support nerve repair and provide a practical source of stem cells for neurological therapies.

In this study, embryonic skin fibroblasts from day E17.5 and postnatal day P5, but not E14.5, effectively supported hair follicle formation, indicating distinct developmental states and differentiation capacities.

This study found that female Holdobaggy goslings have higher melanin content in their dorsal plumage than males, suggesting that initial plumage color can be used for sex identification.

This article reviews the occurrence of ectopic sebaceous glands in hair follicle matrix during hair embryogenesis and reports no new clinical results, indicating unknown pathogenesis and clinical implications.

This study found that melatonin receptor genes play a key regulatory role in the development of goose skin feather follicles during embryonic development.

In this study, in ovo injection of CHIR-99021 promoted the morphogenesis and development of feather follicles in chick embryos by activating the Wnt/β-catenin signaling pathway.

This study found that the miR-140-y-TCF4 axis regulates the proliferation of goose embryonic dermal fibroblast cells by affecting the Wnt signaling pathway, highlighting its role as a dynamic regulator during skin and feather follicle development.

This study identified key genes and miRNAs involved in feather morphogenesis in Zhedong White geese, highlighting a negative correlation between FOXO3 and miR-144-y.

Hair follicles can regrow in wounded adult mouse skin using a process like embryo development.

Cultured hair follicles need careful handling and respond well to growth factors.

In this study, mouse amnion epithelium was successfully transformed into skin and hair follicles when associated with hair-forming dermis, revealing the necessity of specific influences for follicle formation.

This study found that excess vitamin A induced stable glandular morphogenesis and mucous metaplasia in embryonic mouse vibrissa follicles, even after switching to standard medium.

Human hair follicles can provide stem cells for regenerative medicine.

This review discusses current experimental approaches for regenerating human hair follicles using tissue engineering and isolated cells, but reports no successful strategies with adult cells yet found.
