This review discusses the developmental regulation of wound healing mechanisms in mammals, focusing on the role of the Wnt and TGF‐β signaling pathways, and reports no new clinical findings.

This study observed that selectively activating activin in the epidermis of mice enhanced reepithelialization during wound healing without altering the quality of the healed wound.

This review discusses the unique features of fetal wound healing that may enable scarless repair and reports no new experimental findings.

In this study on mice, researchers observed that dermal white adipose tissue (dWAT) plays a key role in regulating skin inflammation and tissue repair; however, reduced expression of certain cytokines in obese mice may hinder these processes, indicating potential metabolic disruptions in dWAT during inflammation.

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.

Activating the Eda/Edar pathway improves wound healing by enhancing hair follicle growth.

In this study, decellularized human amniotic membrane was found to promote wound healing and reduce scar formation in rats with full-thickness skin defects, compared to traditional clinical treatments.

This study found that forming spheroids using silicone micro-wells improved the viability and neural differentiation potential of human adipose-derived stem cells after thawing.

This study observed phenotypic diversity in hair loss among Japanese individuals homozygous for the LIPH c.736T>A mutation and suggests that differences in hair thickness may contribute to varying severities.

In this study, researchers suggest that strategic early intervention during fetal wound healing could lead to significantly improved long-term skin regeneration outcomes.

This chapter reviews classic regeneration models in planarian worms and amphibian limbs, focusing on the role of stem cells, and reports no new experimental results.

This study found that αvβ6 integrin inhibits keratinocyte proliferation during wound healing and hair regeneration, suggesting its downregulation may enhance recovery and influence epidermal stem cell behavior.

This review discusses the various stem cell populations associated with hair follicles and their potential in regenerative medicine, highlighting differences between murine and human hair follicles but reports no new clinical results.

This study found that Wet-type Age-Related Macular Degeneration patients had higher oxidative stress and HMGB-1 levels compared to healthy controls, suggesting a link to increased tissue inflammation and necrosis.

This review examines the epidemiology, pathophysiology, diagnosis, and management strategies for non-classic congenital hyperplasia due to 21-hydroxylase deficiency, and provides evidence-based recommendations for its treatment and genetic counseling.

This case report identifies collagenous gastritis as the cause of chronic gastrointestinal symptoms in a 27-year-old male, characterized by severe chronic inactive gastritis and a distinctive subepithelial collagen band.

This study found that the loss of transcription factor Ovol2 in epidermal and hair follicle stem cells leads to migration defects, which are partially improved by deleting the EMT-inducing Zeb1.

This study established a novel in vivo "whisker follicle microinjection assay" using mouse whiskers to evaluate hair growth and pigmentation effects of various chemicals and proteins, identifying minoxidil, ruxolitinib, and RSPO1 as growth promoters, while deoxyarbutin inhibited pigmentation and Nbl1 emerged as a growth inhibitor.

This review discusses how studying regenerative biology in certain mammalian models could enhance our understanding of complex tissue regeneration, but it reports no new clinical findings.

This study found that STAT5 activation in the dermal papilla acts as a key switch to trigger anagen entry in postdevelopmental hair follicle cycling.
