In this study, probiotic-functionalized nanocomposite scaffolds accelerated wound healing and inhibited harmful bacteria in burn wounds on mice, suggesting a potential new approach for infection control and healing promotion.

This study found that early treatment with αCT1 in wound healing increased collagen synthesis and disorganization, potentially improving long-term scar appearance by altering early collagen matrix formation.

This review discusses the potential of microneedles to enhance transdermal drug delivery by expanding the range of deliverable drugs, highlighting fabrication methods, material choices, and applications, but notes existing challenges with sustained delivery, cost-effectiveness, and large-scale production.

This review discusses how aging affects hair follicle stem cells and their environment, contributing to hair loss, and explores strategies to promote hair regrowth, but reports no new results.

Aging skin is affected by inflammation, reduced stem cell function, and slower wound healing.

This article discusses a potential link between adipocyte-myofibroblast transition and androgenetic alopecia, suggesting AMT may play a role in fibrosis associated with the condition but presents no new results.

This study observed that cutaneous microwounds created by fractional photothermolysis heal differently from typical wounds, displaying rapid re-epithelialization and limited inflammation, which may help reduce scar formation by delaying collagen remodeling and minimizing myofibroblast activation.

This article reviews the stages and regulation of the hair cycle, highlighting molecular regulators involved, but it does not present new research findings.

This review summarizes the major events and regulators of the hair cycle in mammals but reports no new experimental results; it emphasizes the complex regulation of stem cell activation and differentiation during hair growth.

This study found that activating the Sonic hedgehog pathway in scarring wounds can remodel the dermis to promote hair follicle regeneration, highlighting a potential new approach to enhance healing.

In this study, researchers detailed how hair follicles regenerate after microsurgical amputation, observing a wound reaction involving dynamic dermal-epidermal interactions and changes in extracellular matrix components.

This review discusses factors affecting wound-induced hair neogenesis in mice and reports no new results; it aims to facilitate meaningful comparisons of experiments across different laboratories.

This review discusses the fundamental hallmarks of aging as they relate to skin aging and highlights the prominent roles of oxidative damage and the extracellular matrix in photoaging, reporting no new results.

This article aims to enumerate and describe the types of tissue degeneration observed in various dermatopathological conditions, offering beneficial insights for residents studying the deterioration of skin tissues due to inflammatory, infective, drug-induced, or neoplastic stimuli.

This chapter provides an overview of skin physiology, aging effects, and how environmental factors like UV damage impact skin health, without presenting new research findings.

This article discusses the biologic and psychosocial significance of hair, the current limitations in hair growth drugs, and anticipates future therapies based on advancing hair follicle research.

Hair growth is cyclic and influenced mainly by local factors.

This review discusses the role of corticotropin-releasing hormone in human skin, focusing on its regulation, receptors, and functions, and highlights parallels with the hypothalamo-pituitary-adrenal axis; it reports no new research findings.

This study shows that BMP2 and BMP7 play complex, necessary roles in feather development by regulating dermal condensation formation, with BMP7 acting early as a chemoattractant and BMP2 halting cell migration.

This study reports that stimulating sensory neurons with capsaicin and isoflavone increases IGF-I production, promoting hair growth in mice and human volunteers with alopecia.

This chapter reports an organ culture method that permits mouse embryonic skin tissues to develop similarly to in vivo conditions, revealing that epidermal growth factor inhibits hair follicle formation.

This study suggests that exosomes derived from mesenchymal stem cells may promote hair growth and improve skin health by enhancing dermal papilla cell proliferation and modulating inflammation and oxidative stress.
