This study found that implanting hair-follicle-associated pluripotent stem cell sheets in mice significantly accelerated wound closure and reduced scar formation compared to non-implanted controls.

This study found that Dab2 conditional knockout mice experienced delayed hair follicle cycles and reduced hair follicle stem cell activity, suggesting Dab2's crucial role in regulating stem cell activation and anti-aging process in hair follicles.

This study identified 674 differentially expressed proteins in the skin tissues of male and female Chinese merino sheep, suggesting gender-specific molecular mechanisms that may affect wool traits.

This article reviews the functions and locations of skin stem cells and their role in regeneration and differentiation, relating age-associated skin changes to decreased stem cell functionality; it reports no new experimental findings.

This study identified genes that may regulate cashmere fineness in Liaoning Cashmere Goats by analyzing skin cell types and exploring gene expression in secondary hair follicle dermal papilla cells.

This letter to the editor presents a case of non-Herlitz junctional epidermolysis bullosa associated with a COL17A1 mutation and reports no new clinical findings.

In this study, researchers identified a collagen fragment, sample-1707, expressed in E. coli, which forms nanofibers and promotes blood clotting, osteoblast differentiation, and skin cell regeneration, making it a promising biomaterial for skin care, with a large-scale production yield of 600 mg/L.

This study found that Punica granatum ethanolic leaf extract may alleviate skin fibrosis in rats by modulating inflammation-related pathways and reducing dermal alterations.

This study found that exosomes from human umbilical cord mesenchymal stem cells reduced hair follicle aging and promoted hair regeneration in models by upregulating COL17A1 through the miR-21-5p/DKK2/Wnt/β-catenin axis, outperforming existing treatments like minoxidil.

This study reported that Cacumen Platycladi extract significantly reduced hair loss and increased hair density in a 12-week clinical trial, suggesting it may be a safe and effective natural treatment.

Dark skin has stronger barriers and structure due to specific gene activity.

This study identified key proteins, FKBP10 and FBN2, that promote the growth cycle of secondary hair follicles in cashmere goats, with higher expression in the anagen phase, offering insights into mechanisms potentially enhancing cashmere yield and quality.

HA-iMSC-EVs can improve skin aging by boosting cell growth and restoring collagen and elastin.

This study found that an extract from the herbal medicine Ophioglossum vulgatum Linn. showed potential hair growth promotion and increased ATP and catalase activity in cell assays, suggesting its use in treating alopecia.

This study found that apocynin restored collagen production, reduced DNA damage and senescence, and protected skin stem cells from aging in UVB-exposed human keratinocytes.

This study found that implanting HAP stem cells in a mouse model accelerated wound closure and reduced scar formation, suggesting potential for scar-free wound healing.

This study found that apocynin restored COL17A1 expression in human keratinocytes and reduced UVB-induced cellular senescence, DNA damage, and cell cycle arrest.

This study found that a cell therapy product, RCS-01, was well tolerated in aged skin and led to significant increases in gene expression related to extracellular matrix homeostasis, although the small cohort size limited further efficacy analysis.

This study found that in mice, type XVII collagen is essential for controlling epidermal cell proliferation through Wnt signaling, with its deficiency or altered distribution leading to skin hyperproliferation and aging-like changes.

This study found that type XVII collagen (COL17) regulates interfollicular epidermis proliferation in both neonatal and aged mice through Wnt signaling, suggesting its potential as a target for anti-aging skin strategies.

This study found that type XVII collagen is crucial for regulating epidermal cells' proliferation in mice and may be a promising target for anti-aging skin treatments.

This study found that COL17 plays a key role in regulating epidermal keratinocyte differentiation and proliferation, influencing the expression of differentiation markers and cellular growth in specific conditions.

This study found that P. cornucopiae extract showed antioxidant and protective effects on human skin fibroblasts, suggesting its potential as an antiaging agent by preventing oxidative stress-induced collagen breakdown.

This research found that Foxc1 promotes quiescence in hair follicle stem cells and identified COL17A1 depletion, due to DNA damage, as a cause of hair thinning and loss during aging.

The meeting highlighted the genetic basis of female pattern hair loss and various skin health insights.

In this laboratory study, the researchers found that combining dermal papilla cell-derived exosomes with collagenous sequences significantly enhanced hair follicle stem cell migration and proliferation, highlighting a potential strategy for hair regeneration through modulation of the hsa-novel-238a-CASP9 axis.

This study found that decreased COL17α1 expression in aging mouse skin is associated with reduced proliferation of epidermal stem cells and may contribute to thinner epidermis and slower wound healing.
