This article reviews the cellular and molecular processes of acute and chronic wound healing, emphasizing the need for collaboration between researchers and clinicians to advance therapeutic solutions; it presents no new clinical results.

This study suggests that mNotch expression plays a significant role in hair follicle differentiation and cell fate selection within the follicle during development.

This review highlights recent advances in chitosan-based nanoparticles (CS NPs) for drug delivery, discussing their modifications, preparation methods, production with organic and inorganic materials, and their latest implementations in the field, emphasizing the role of CS NPs in improving drug transport and release properties.

This study suggests that exosomal miRNAs from human amniotic fluid stem cells may inhibit myofibroblast differentiation and reduce fibrotic scarring in wound healing.

This study found that the absence of laminin α5 in adult mice's epidermal basement membrane led to keratinocyte hyperproliferation and immune cell changes, affecting hair follicle development through altered growth factor expression.

This study found that Gelatinase A activity is linked to the absence of type VII collagen during human fetal skin development, indicating its role in remodeling the basement membrane zone.

In this study, the researchers identified the specific subcellular localization of the protein S100A3 in the endocuticle and cortex of human hair shafts.

This study found that the Gsdma3 gene is necessary for normal hair follicle differentiation in mice, with its mutation leading to progressive hair loss and defects in hair structure.

This study found that cytokine and EGF stimulation leads to increased MMP-9 production in hair follicles, a process involved in hair follicle involution associated with alopecia.

The study found that up-regulating β-catenin signaling in CD 133-positive dermal papilla cells enhanced their ability to promote hair follicle regeneration both in vitro and in vivo.

This study found that 3D-printed polyamine-modified hydrogels facilitate M2 macrophage polarization and exosome secretion, enhancing skin cell compatibility and promoting wound healing and hair follicle induction in an animal model through specific signaling pathways, suggesting potential for skin disorder therapies.

This study found that mesenchymal cell processes from the dermal papilla contact epithelial hair matrix cells through gaps in the basal lamina during hair matrix cell differentiation in mouse vibrissa follicles.

This review discusses the roles of the transcription factor SOX9 in organ development and maintenance, providing insights into its regulation and diverse functions, but reports no new experimental results.

This review discusses the role of tissue mechanics and extracellular matrix in skin aging processes and highlights potential therapeutic strategies, but reports no new clinical results.

This study found that subthermal CRET treatment increased keratinocyte proliferation and modulated cytokine production, affecting the inflammatory response in human keratinocytes through EGFR and ERK1/2/NF-κB pathways.

This review discusses the mechanisms and potential benefits of platelet-rich plasma therapy for various skin conditions and reports no new clinical findings.

In this study, the researchers developed a hydrogel mimicking the fetal environment that significantly accelerated wound healing and hair follicle regeneration in vivo, with over 94% wound closure in 14 days, surpassing hydrogels lacking certain additives.

This study found that Centipeda minima and brevilin A significantly reduced oxidative stress and inflammation in human dermal fibroblasts, suggesting their potential to protect against skin aging and inflammation.

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 study reviews the role of exosomes in regenerative aesthetics, highlighting their potential in treating conditions like photoaging and wound healing through mechanisms like matrix remodeling and immunomodulation, while also noting advancements in exosome isolation techniques and regulatory considerations.

In this study, researchers used a 3D in vitro organ culture system to show that rifampicin-loaded lipid nanocapsules can penetrate hair follicles more effectively than free rifampicin, highlighting the potential advantage of nanocarrier-based antibiotic treatments for follicular infections.

This study suggests that incorporating matrisomal components into biomaterials could enhance skin wound healing in mammals that do not naturally regenerate tissues like the axolotl and Acomys.

This study found that the wild-derived mouse strain Mus pahari has fragile skin that separates at subdermal levels under moderate force, potentially due to altered extracellular matrix development.

This study reports that androgenetic alopecia patients exhibit reduced CK15 and tropoelastin expression and increased cellular senescence markers, indicating tissue damage in affected hair follicles and surrounding structures.

This study found that prolactin and melatonin both stimulated hair shaft elongation in Cashmere goat hair follicles, with maximum growth observed at specific concentrations, although melatonin reduced follicle viability after 96 hours.

This study found that matrix progenitor cell differentiation in hair growth has distinct early and late phases, and generated a mouse model to explore the hair follicle's role in harlequin ichthyosis.

This study observed that nearly 70% of children with treatment-resistant alopecia areata had nail involvement, predominantly pitting, which was significantly linked to longer disease duration but not the severity of scalp hair loss.

This study observed that nearly 70% of children with treatment-resistant alopecia areata had nail involvement, and while this was associated with longer disease duration, it did not correlate with the severity of scalp hair loss.

The researchers reported that a 4-aminopyridine-loaded gel promoted wound healing and hair follicle regeneration in burn models, suggesting it might be a promising alternative to existing burn treatments.

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.
