This study suggests that dihydrotestosterone plays a key role in the development of chronic allograft nephropathy, and inhibiting androgens may improve long-term kidney transplant outcomes.

In this study using rabbits, HA2 hydrogels made from cross-linked hyaluronic acid and polysaccharide promoted wound healing better than other treatments, reducing inflammation and scar formation.

This review explores the role of regulatory T cells in autoimmune skin disorders like alopecia areata and vitiligo, emphasizing unanswered questions and reporting no new experimental results.

In this study, CD109 overexpression in transgenic mice led to reduced inflammation and improved collagen organization during wound healing without affecting wound closure.

In this study, Salvia plebeia extract promoted hair growth by enhancing proliferation and anti-apoptotic effects in human dermal papilla cells and increased hair growth in treated mice.

This study suggests that crosstalk between Wnt/β-catenin and TGF-β signaling pathways may contribute to the development of androgenetic alopecia.

This study found that the synthetic thyroid hormone receptor modulator KB2115 significantly prolonged the growth phase of human hair follicles in culture without altering mitochondrial activity, suggesting potential as a safer hair loss treatment compared to traditional thyroid hormones.

In this study, intradermal injection of botulinum toxin was associated with increased hair growth in men with androgenetic alopecia through the suppression of TGF-β1 secretion from dermal papilla cells.

This study found that neural stem cell extract enhanced hair growth in mice and cells by stimulating hair follicle niches and activating signaling pathways like TGF-β and BMP.

In this study, the herbal complex of Houttuynia cordata, Perilla frutescens var. acuta, and green tea promoted hair growth in C57BL/6 mice, enhancing regrowth and follicle development compared to controls.

This study suggests that D-panthenol may promote hair growth by enhancing cell viability, suppressing apoptosis markers, and elongating the anagen phase in human hair follicle cells.

This study found that intracellular Toll-like receptors were significantly up-regulated in peripheral blood mononuclear cells of alopecia areata patients, suggesting a potential role in inflammatory signaling and pathogenesis.

This study found that extracellular vesicles derived from mesenchymal stem cells and umbilical cord blood plasma enhanced wound healing and reduced scar formation in mice, suggesting their potential as therapeutic agents for skin repair.

This study suggests that Platycarya strobilacea extract promotes hair growth in mice by enhancing stem cell factor expression, reducing mast cell numbers, and increasing cytokines associated with hair growth.

This study observed that reduced activation of SMAD2/3 proteins in cutaneous squamous cell carcinoma tissue compared to adjacent tissue may indicate a tumor suppressor role in disease progression.

This study found that mycophenolate may stabilize β-catenin and counteract interferon-γ-induced catagen changes in human dermal papilla cells, which could promote hair growth.

This review reports that natural compounds show promise in slowing skin photoaging by targeting cellular pathways in keratinocytes and fibroblasts. However, comprehensive clinical studies are needed to verify their efficacy and safety.

The study found that exogenous decorin administration accelerated the anagen phase and delayed the catagen transition, suggesting it may act as a positive regulator of the hair cycle.

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.

In this study, the methanol-ultrasound extract of Dendropanax morbifera leaf showed potential for use in functional cosmetics and hair growth products due to its high antioxidant capacity and effects on growth factor expression without cytotoxicity.

This study found that TGF-β1 expression in follicular tumors correlates with differentiation degree and suggests its potential role alongside p63 in differentiating between sebaceous and follicular tumors.

This article discusses how nutritional and environmental factors, along with antioxidant supplementation, may improve hair growth by mitigating the effects of androgens and reports no new clinical results.

This study found that Nelumbinis Semen extract may promote hair growth and reduce hair loss by increasing VEGF and IGF-1 expression and decreasing TGF-β1 in human dermal papilla cells and mice.

This study observed that the OCIAD2 and DCN genes in Liaoning cashmere goats have opposite effects on hair growth by interacting with the TGF-β signaling pathway, influencing follicle morphogenesis and periodic changes.

This study found that transplanting hair follicles into human scars may remodel fibrotic tissue and reduce scarring by altering collagen structure and decreasing pro-fibrotic factors.

In this study, adipose-derived stem cells from human scalp were successfully directed towards chondrocyte differentiation, with TGF-beta3 and BMP-6 growth factors proving effective for in vitro chondrogenesis.

Botulinum toxin may help hair loss by increasing blood flow and reducing harmful factors.

Ch55 may help reduce skin scarring and fibrosis.

This review article highlights the potential of mesenchymal stem cells, their exosomes, and non-coding RNAs in repairing aging skin tissues due to their ability to secrete beneficial compounds, suggesting their promising role in photoaging treatment without causing immune rejection or granuloma formation.
