In this study, a biofunctional hydrogel incorporating mesenchymal stem cell-derived small extracellular vesicles promoted wound healing and reduced scar tissue formation by modulating the immune response in a mouse skin injury model.

In this study, CD4+CD25+FoxP3+ Regulatory T cells were found to reduce TGF-b1 induced lung fibrosis and fibrocyte accumulation in mice, partly by suppressing fibroblast growth factor 9.

Minoxidil affects collagen-related genes, potentially helping treat fibrosis.

This review examines the complexities of age-related skin healing and discusses how translating findings from model organisms to humans could enhance understanding and treatment of impaired regeneration in aging populations, but it reports no new clinical results.

This study identified key long non-coding RNAs and mRNAs involved in primary wool follicle induction in carpet wool sheep, emphasizing their roles in hair follicle development and skin processes.

Overexpression of certain genes can shorten hair by disrupting the hair-growth cycle.

This study suggests that the action of minoxidil in stimulating hair growth likely occurs at the follicular dermal papilla, though it does not induce new follicle formation.

This study found that SIRT1 negatively regulates fibroblast activation and excessive scar formation, suggesting it may be a promising drug target for treating hypertrophic scars.

Injecting platelet-rich plasma (PRP) can increase hair growth rate and density in male pattern baldness.

This study found that white hair exhibits increased expression of genes and proteins linked to active hair growth compared to black hair, suggesting that hair greying is associated with enhanced hair growth activity.

This study found that mechanical stress activates a WISP-1/Hedgehog signaling axis that contributes to ligamentum flavum hypertrophy and fibrosis, identifying Hedgehog signaling as a potential therapeutic target.

This study found that Wnt7a-containing conditioned medium from UC-MSCs can accelerate wound healing and promote hair follicle regeneration by enhancing specific cellular functions in the wound microenvironment.

This narrative piece considers how epigenetic factors may influence the processes of skin wound healing, including hair follicle formation, but it presents no new experimental results.

This study found that activating liver X receptors with an agonist reduced skin fibrosis in experimental models, particularly in inflammation-driven conditions, by inhibiting macrophage infiltration and interleukin-6 release.

This review examines the mixed evidence on mast cells as regulators of skin fibrosis and highlights existing gaps in the scientific understanding, reporting no new experimental results.

This study found that fibromodulin significantly reduces scar formation and boosts scar strength in rodent and porcine models, suggesting potential for FMOD-based therapies in cutaneous wound repair.

This study found that red light accelerated the transition from the resting to growth phase in hair follicles faster than green and blue light in mice, suggesting it may stimulate hair growth.

This study found that basement membrane components and structures in mouse hair follicles are highly specialized for specific inter-tissue interactions, with laminin α5 playing a crucial role in hair cycle regulation and anchoring.

This research found that hyaluronic acid increased cell proliferation and type I collagen more effectively than poly-L-lactic acid in both human fibroblast cultures and rat dermis.

This study found that Ecklonia cava enzymatic extract, particularly its component dieckol, promoted hair growth by increasing dermal papilla cell proliferation and inhibiting 5α-reductase activity in cultured vibrissa follicles and C57BL/6 mice.

This study found that loading CoQ10 into a protransfersomal emulgel improved its stability and anti-ageing effects in UV radiation skin-aged induced-mice, without causing skin irritation.

This study found that the application of calreticulin significantly improved wound healing time and quality in diabetic mice, suggesting it may be an effective topical treatment for chronic wounds.

In this study, mouse amnion epithelium was successfully transformed into skin and hair follicles when associated with hair-forming dermis, revealing the necessity of specific influences for follicle formation.

MicroRNA-21 could help diagnose and treat skin fibrosis.

This study reports that Cur@CMCTS-Tk hydrogel effectively accelerated wound healing and tissue regeneration in rats by scavenging excess reactive oxygen species and protecting human fibroblasts from oxidative damage.

This study demonstrates that FMOD deficiency in mice alters TGF-β ligand and receptor expression during wound healing stages, leading to delayed wound closure and increased scar size.

SACUMAN, a rare condition causing hair loss without clear signs, is often misdiagnosed and needs scalp biopsies for accurate detection.

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 report presents the second known case of erythema nodosum without typical associated conditions, which could be linked to mycoplasma infection, although no testing was conducted to confirm this in the patient.

This review updates the protective effects and molecular mechanisms of melatonin against ultraviolet-induced damage in human skin, reporting no new clinical findings.
