This review discusses the differences in wound healing between fetal and adult skin, highlighting the potential to uncover genes for scarless repair that could improve adult wound healing.

In this study, intradermal injections of QR678 were found to significantly reduce hair fall in men with androgenetic alopecia over 6 months, with superior improvements in hair density and thickness compared to PRP.

In this study, QR678® and QR678 Neo® injections significantly improved hair density and thickness in women with PCOS-related alopecia over eight sessions, with effects lasting over a year.

This study reports that a 30% ethanol extract of a plant mixture enhanced hair growth in human hair dermal papilla cells and mice, suggesting potential use in hair growth products.

This review highlights how single-cell transcriptomics has advanced understanding of tissue regeneration by revealing cellular diversity and key molecular interactions in animal models, despite methodological challenges, suggesting future applications in developing targeted regenerative therapies.

This study suggests that administering SH-MSCs gel might decrease IL-6 expression and increase TGF-β expression in alopecia-like rats, indicating potential for alopecia therapy.

This study found that epidermal Wnt production is crucial for forming the skin's spinous layer through a BMP-FGF signaling cascade, although Wnt from basal cells is not needed for their differentiation.

This study found that 6-Gingerol significantly suppressed hair growth in mice by reducing hair follicle number and length, potentially through increased expression of MMP2 and MMP9.

This study found that 675 nm laser treatment improved androgenetic alopecia in Indian patients, resulting in significant increases in hair count, density, and thickness after 14 sessions, enhancing the anagen phase and other hair-related parameters.

This study found that cetaceans have adapted their fibroblast growth factors to assist in low bone density, hypoxia tolerance, and the development of rigid flippers, reflecting significant evolutionary changes for aquatic life.

This study found that in C57BL/6 mice, treatment with fermented red ginseng marc, a traditional polyherb formula, or a combination of both, promoted hair growth by enhancing the hair-growth cycle.

This study identified ectodin as a novel BMP inhibitor that modulates BMP signaling in ectodermal development by interacting with SHH and FGF pathways.

This animal study found that Laminaria japonica mixed with insulin-like growth factor-1 significantly promoted hair growth in mice, suggesting its potential use for treating alopecia pending further clinical trials.

Among in vitro and in vivo models, this study found that Miscanthus sinensis var. purpurascens flower extract may promote hair growth, potentially by modulating growth factor expressions and facilitating earlier hair follicle transitions in treated mice.

This review discusses the life cycle and homeostasis of hair follicles, highlighting their development and the complex signaling between dermal and epithelial cells, but it reports no new clinical results.

This review highlights the significance of animal fibers, examining the molecular mechanisms influencing hair follicle development and their impact on fiber quality and quantity, with a focus on studies involving Angora and cashmere goats.

This study found that fibroblast growth factor 5 may enhance Cashmere goat hair growth by altering the expression of specific genes related to keratin and keratin-associated proteins.

The study reports that Fgf18 and Tgf-β2 signaling pathways in hair follicle stem cells have opposing effects on the timing of hair cycle transitions, influencing the shift from telogen to anagen phases.

This review discusses recent discoveries about the role of Eda and other TNF-related cytokines in skin appendage development and reports no new experimental results, highlighting developments since the last comprehensive summary in 2003.

This study found that MYC and FGF pathways are crucial for hair cell regeneration in chick and zebrafish models, suggesting potential targets for promoting hair cell regeneration in mammals.

This review examines a study showing that the balding scalp in men with androgenetic alopecia retains stem cells but lacks certain progenitor cells, suggesting new targets for future therapies; it reports no clinical results.

In this study, a medicated hair growth tonic containing RJ extract increased hair counts, the proportion of anagen phase hairs, and scalp moisture in human trials, although the specific role of RJ in hair growth remains unclear due to other active ingredients.

This review discusses mesenchymal–epithelial interactions in hair follicle development and cycling, highlighting recent insights without reporting new experimental results.

This review examines the role of nerves in regeneration across various species and discusses their importance as components in the progenitor cell niche, reporting no new clinical results.

This study found that FGF signaling is necessary for the initiation of feather placode development in chicken embryos, with FGF10 being implicated as an early dermal signal in the process.

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 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 research found that feather pattern formation in birds is regulated by a mechanochemical system involving fibroblast growth factor and bone morphogenetic protein signaling, which is altered in the flightless emu and ostrich.

This article discusses the association of acne with various systemic diseases, emphasizing the role of androgen steroids, insulin resistance, and inflammation in acne pathogenesis, but it reports no new clinical results.

This study found that epidermal and fibroblast growth factors increased proliferation of human hair bulb papilla cells and root sheath fibroblasts in vitro, while hydrocortisone decreased it and minoxidil had no effect.
