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.

This study found that autologous serum platelet-rich plasma improved skin quality and reduced wrinkles, texture, and pores in healthy females, partly by regulating the expression of MMP-1, tyrosinase, fibrillin, and tropoelastin.

This study found that cysteine supplementation significantly increases keratin expression in human keratinocytes, and counteracts the negative impact of iron deficiency on keratin production by enhancing iron availability for cellular processes.

In this study, prolonged systemic administration of 17β-estradiol in castrated male mice delayed wound healing by inhibiting re-epithelialization and reducing collagen accumulation, with estrogen receptor-α likely mediating this effect.

This review discusses the unique capacity of fetal skin to heal wounds without scarring and notes that while many factors have been identified, the complete mechanism of fetal wound healing remains unclear.

This study suggests that type IV collagenases, MMP-2 and MMP-9, play important roles in the hair cycle by regulating the expression of VEGF, IGF-1, and TGF-β in mice.

This study identified 12 new genes associated with the hair follicle and various stages of the hair cycle in mice, which could lead to novel targets for hair growth or depilation therapies.

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.

This study identified upregulation of genes linked to fibroproliferative disorders, such as platelet-derived growth factor and collagen genes, in patients with central centrifugal cicatricial alopecia, suggesting potential therapeutic targets.

This study found that non-ablative fractional erbium glass laser treatment affected gene regulation in human skin models by downregulating MMP and interleukin expression, suggesting potential roles in dermal remodeling and anti-inflammatory effects.

This study found that supplementing pregnant and lactating mice with high dietary copper improved survival and physical traits in mice carrying the crinkled mutation, suggesting copper's role in modulating gene expression.

This review discusses the role of jasmonic acid and its conjugates in enhancing plant stress tolerance and balancing growth and defense mechanisms but provides no new experimental data.

This review explores the skin regeneration process in spiny mice and highlights differences from laboratory mice, focusing on potential molecular and immune system roles without reporting new experimental results.

This study found that proteins secreted by early-passage dermal papilla cells, including SDF1, MMP3, biglycan, and LTBP1, may play significant roles in hair follicle regeneration.

This review explores the role of neutrophil recruitment in the inflammation seen in hidradenitis suppurativa and emphasizes potential therapeutic targets within these pathways, but it reports no new clinical results.

This study found that two pre-Hispanic mummies from the Andean coast had well-preserved hair with significant amounts of heavy metals like iron, lead, bromide, and occasionally arsenic, revealing their historical context.

Among Australian fur seals at one colony, this study found that alopecia, primarily affecting juvenile females, is linked to hair shaft fractures associated with low tyrosine and zinc levels, as well as higher pollutant exposure.

This review examines non-surgical methods for rejuvenating the periorbital area and highlights the growing role of platelet-rich plasma, but it reports no new clinical findings.

This study found that photoexposure significantly increased the gene expression of altered elastin, MMP12, and LOX, as well as the protein expression of tropoelastin and fibrillin-1, in skin models.

This study observed that aging leads to significant structural and biological changes in the scalp's hair follicle environment in women, which may affect hair growth.

This study found that a newly synthesized peptide from fermented Trapa japonica extract significantly promoted wound recovery and showed antiaging effects in skin cells and a clinical study, suggesting potential as a cosmetic product.

This study found that cadmium levels were significantly higher in women with chronic telogen effluvium compared to healthy controls, suggesting cadmium toxicity might contribute to this hair shedding condition.

This study reports that the newly developed natural dye-based sindoor is safe for skin application and offers a non-toxic alternative to synthetic dye-based sindoor.

In a study using hairless mice, tranexamic acid was found to ameliorate natural skin aging, with stronger effects observed in female mice compared to males.

Platelet-rich plasma (PRP) may help promote hair growth and improve graft survival after hair transplantation, but more research is needed to confirm its effectiveness and determine the best dosage.

This review explores hair signs related to nutrition disorders, such as thin and dyspigmented hair, without presenting new clinical findings; the authors highlight unknowns regarding underlying causes.

In this animal study, ginsenoside Rb1 demonstrated therapeutic effects on hypertrophic scar remodeling, with the highest efficacy observed at a dose of 0.56 mg.

This study suggests that CTHRC1, a protein expressed in cardiac fibroblasts, may improve wound repair and prevent cardiac rupture after myocardial infarction by activating a specific signaling pathway.

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 hydro-alcoholic Eclipta alba extract may have anticancer and multidrug resistance-reversal effects in animal models, suggesting potential as an adjunctive agent in tumor chemotherapy.
