This case report highlights an 11-year-old girl with dermatopathia pigmentosa reticularis, identifying associated Salzmann's nodular degeneration of the cornea and emphasizing the need for a multidisciplinary management approach.

In this study, researchers explored the molecular and cellular traits of avian reticulate scales, finding that they lack localized stem cell niches for regeneration, unlike other scale types, leading to repair but not regeneration after wounding.

This study found that a silk fibroin/sodium alginate scaffold effectively delivers human umbilical mesenchymal stem cells to promote scarless wound healing and hair follicle regeneration in vivo by inducing specific cellular processes and mitigating endoplasmic reticulum stress.

This study found that probiotic-functionalized silk fibroin/alginate scaffolds, loaded with Lactobacillus casei, promoted scarless wound healing and hair follicle regeneration in infected wounds in rats.

Minoxidil can cause pustular allergic reactions on skin.

This review explores fibroblast heterogeneity in the mammalian dermis and suggests potential therapeutic applications by targeting fibroblast subtypes, but reports no new experimental results.

This study found that Ng2+ perivascular cells in mouse skin are a diverse lineage-restricted population primarily recruited from papillary or reticular fibroblast lineages during wound healing, maintaining heterogeneity in both wounded and non-wounded skin.

This case report describes a 29-year-old Japanese man with follicular mucinosis, suggesting nestin-positive, multipotent hair follicle stem cells may be involved in reticular epithelial degeneration of the outer root sheath.

This review explores the evolution and development of skin-associated adipose tissue and proposes new nomenclature for the cells and adipose tissue underlying the reticular dermis, without reporting clinical results.

This study found that Pannexin 3 plays a crucial role in skin development by regulating the transcription factor Epiprofin, affecting keratinocyte differentiation and hair follicle regeneration in mice.

This study examined the formation of acquired curved hair and found that the fusion of hair matrix cells during follicle regeneration contributes to asymmetric follicle shapes and curved hair, potentially linked to changes in type IV collagen and protein expression levels.

This study observed that Hedgehog signaling in reticular and papillary fibroblast lineages plays different roles in wound repair and de novo hair follicle formation.

This study observed that in mouse fetuses, reticular contraction by actomyosin is involved in dermal regeneration, and differences in actin and α-SMA localization may determine the switch between regeneration and scar formation, suggesting potential insights for wound regeneration therapy.

This review explores current knowledge on fibroblast lineage specification and its impact on scar-free wound healing, noting that early fetal skin fibroblasts support regeneration, while later developmental shifts lead to fibrosis, highlighting potential strategies to reprogram adult fibroblasts for regenerative repair.

This case report details a 21-year-old woman with dermatopathia pigmentosa reticularis, presenting with generalized reticulate hyperpigmentation, diffuse noncicatricial alopecia, onychodystrophy, palmoplantar keratoderma, and poorly developed dermatoglyphics.

This review discusses dermal cell heterogeneity in wound healing and scar formation, highlighting the varied roles of different fibroblasts and the potential of skin substitutes without presenting new clinical results.

This study found that ECMs from papillary and dermal papilla fibroblasts support normal basement membrane formation, suggesting potential improvements for therapeutic biomaterials in skin engineering.

This study discovered that adipose tissue infiltration at the isthmus level appears significantly more often in frontal fibrosing alopecia cases compared to controls, suggesting a potential role in the condition's pathology.

This study identified two novel genetic variants associated with Alzheimer's disease in APOE ε4 non-carriers, revealing insights into the disease's underlying regulatory mechanisms.

Mast cells and VEGF contribute to post-surgery adhesions, and blocking VEGF can reduce these adhesions; also, certain factors affect wound healing and fetal skin heals differently with age.

This correspondence discusses follicular mucinosis in association with pregnancy but does not report new clinical results, instead calling attention to the observed connection.

This study suggests that human skin contains distinct fibroblast subsets with unique expression profiles and functions, which can be isolated to investigate their role in skin pathogenesis.

This study found that telocytes are present in the human dermis, suggesting a potential role in skin homeostasis, remodeling, regeneration, and repair.

This study found that CD26+ fibroblasts are crucial for effective extracellular matrix production and achieving rapid epidermal and dermal homeostasis in human tissue-engineered skin substitutes transplanted onto rodents.

Certain cells around hair follicles help improve skin regeneration for potential use in skin grafts.

Mammalian organs regenerate using stem cells and cell plasticity, but this ability declines with age.

This study demonstrates that canonical Wnt signaling is crucial for maintaining thymic epithelial microenvironments in postnatal thymus, possibly by affecting TEC progenitor cells.

This research suggests that targeting the HIF-1α pathway via PHD inhibitors may enable regeneration similar to amphibians in mammals, potentially fast-tracking regenerative therapies from mice to humans.

In this review, the authors explore strategies for inducing scarless skin regeneration by modulating dermal signaling or specific fibroblast subsets to promote the formation of new hair follicles in wounds, particularly focusing on mimicking neonatal skin's regenerative capabilities.

This study suggests that hair follicle dermal stem/progenitor cells play a key role in both hair regeneration and skin wound healing, with potential implications for preventing hair follicle miniaturization linked to aging or alopecia.
