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.

In this study using a mouse model, Prom1+ dermal papilla cells were found to regulate the size of the papilla via β-catenin communication but did not aid in dermal repair.

This study demonstrated that β-catenin signaling in CD133+ dermal papilla cells enhances postnatal hair growth by accelerating the proliferation and differentiation of keratinocytes in the murine hair cycle.

This study found that macrophage-stimulating protein (MSP) enhanced hair growth in both human hair follicles cultured in vitro and in mice through the promotion of anagen phase induction.

This review discusses the role of defensin peptides in stem cell activation for potential skin rejuvenation therapies and reports no new clinical findings, emphasizing the need for further studies.

This study found that resveratrol and fisetin promoted hair growth in mice by inducing telomerase reverse transcriptase expression, which activates hair follicle stem cells and transitions follicles from a resting to a growth phase.

This study found that 5% primed conditioned medium from human umbilical cord blood-derived mesenchymal stromal cells significantly improved hair density, thickness, and growth rate in patients with androgenetic alopecia.

This study suggests that miRNAs, particularly miR-195-5p, may regulate the loss of hair follicle inductivity in cultured dermal papilla cells by suppressing the Wnt/β-catenin pathway.

This study identified distinct gene expression patterns in wool follicle bulbs that may play important roles in wool follicle cycling and regeneration in sheep.

This review discusses recent findings on molecular changes in cutaneous adnexal tumours and reports novel markers and pathways involved, highlighting the diverse oncogenic drivers and tumour suppressor alterations.

This study found that phyto-vesicles of ß-sitosterol showed better absorption and improved activity for treating androgenetic alopecia in rats compared to the compound and its complex.

In this study, researchers found that the pCLCA2 protein is expressed in specific areas of pig skin, but its role in skin structure or function remains unclear.

This study observed that adipose-derived stem cells modified with trichogenic factors have similar properties to dermal papilla cells and show enhanced hair regeneration potential compared to unmodified adipose-derived stem cells.

Junctional proteins stabilize the inner root sheath and connect the companion layer in human hair.

This article discusses the roles of dermal papilla and sheath cells in hair follicle formation and regeneration but reports no new clinical findings, emphasizing the need for further research on these fibroblasts.

This study found that Wnt10b promotes the proliferation of hair follicle stem cells and hair precortex cells, revealing them as target cells in Wnt10b-induced hair follicle regeneration.

This chapter discusses the skin stem cell niche as a complex ecosystem and highlights the diverse components and interactions that influence stem cell function, but it reports no new experimental results.

This study suggests that an in ovo injection of CHIR-99021 promoted feather growth and follicle development in goose embryos by activating the Wnt signaling pathway.

This review discusses the potential for cellular hair regeneration by building on foundational rodent studies and emphasizes the need for protocols to enhance the inductive properties of human dermal papilla cells.

This study found that small amounts of RNA present in horsehair roots can be used for molecular biological analysis, although detecting mRNA transcripts in the hair shaft is more challenging.

This study found that endothelin produced by hair follicle progenitors activates contractions in dermal sheath cells, facilitating hair follicle regression in the growth cycle.

This study suggests that β-catenin plays an important role in wool follicle development in transgenic sheep by enhancing the expression of keratin protein genes.

This study demonstrated that vitamin B12 may promote hair growth in vitro by modulating intracellular signaling in the wnt-pathway, suggesting potential benefits for micrograft transplantation.

In laboratory settings, this study suggests that Serenoa repens and N-acetyl glucosamine with milk proteins may promote hair follicle vascularization through specific cellular interactions and actions.

This study suggests that IGF-1, a component of human placenta hydrolysate, promotes hair growth by increasing the number and size of hair follicles in mice.

This study identified dual epithelial and mesenchymal traits in dermal sheath cells during wound repair, suggesting they could be targeted to enhance healing.

This review explores the roles of dermal sheath cells in wound healing, highlighting their multifunctional contributions to inflammation, proliferation, and extracellular matrix remodeling, and proposes new insights into tissue regeneration and repair, especially in differentiating between hairy and non-hairy skin sites.

In this study, the expression of Gnαs was significantly higher in black mice compared to white mice, suggesting its potential involvement in coat color formation in mice.

This review discusses the role of Sox2 in skin development, hair follicle regeneration, cancer, and wound healing, and reports no new experimental results.

This study evaluated Korean herbal compounds in silico and identified Biochanin A, Saponin Re, and Emodin as potential topical treatments for androgenetic alopecia, each with specific safety and efficacy considerations.
