This review proposes an anatomy-based framework for understanding recipient site scalp necrosis in hair transplantation, emphasizing regional vascular vulnerability and surgical factors, but does not provide new clinical results.

This study found that "micro skin tissue columns" improved wound healing by enhancing re-epithelialization, collagen deposition, dermal remodeling, and reducing inflammation without causing long-term donor site morbidity.

This study found that endothelin-1 increases adhesion and chemotaxis of amelanotic melanocytes on fibronectin, laminin, and collagen IV, potentially through changes in the actin cytoskeleton.

A single medium, PRIME AIRLIFT, supports better human hair follicle formation in grafts.

This study found that in vivo confocal scanning laser microscopy accurately quantifies neogenic hair follicles in mice, producing results similar to histology while avoiding fixation artifacts.

Highly active but fewer CD14+CD16- monocytes are found in Alopecia Areata patients, regardless of severity.

This study found that injecting highly purified monocyto-angiotropin into hare skin induced new blood vessel formation and significantly accelerated hair growth at the injection site compared to control areas.

This study found that microencapsulation combined with iontophoresis can significantly enhance the delivery of minoxidil sulphate to hair follicles, suggesting a synergetic approach for topical drug targeting.

This protocol describes a method for cultivating stem cells on a fibrin carrier for potential transplantation to the eye, but it reports no new clinical findings.

This study found that using hyaluronic acid microneedles to deliver minoxidil significantly reduced hair loss in chemotherapy-induced alopecia mice, with only 10% of the dose used in topical applications.

The researchers reported that mesenchymal stem cells promote wound healing by using Cx43 hemichannels to mediate ATP secretion, which supports macrophage polarization, angiogenesis, and fibroblast migration, suggesting a potential therapeutic strategy for improving tissue repair.

This article discusses the potential involvement of hair follicle melanocytes in follicular vitiligo, noting a pattern of depigmentation centered on follicles and supported by inflammatory infiltrates, without reporting new clinical results.

This study found that human dermal papilla cells are embedded in a basement membrane-like extracellular matrix, which is essential for their aggregation and function, as supported by evidence that Matrigel enhances dermal papilla cohesion and gene expression compared to collagen I, which promotes cell dispersion.

The micropunctiform technique for hair restoration is safe, simple, and creates a natural hairline.

This study observed that three-dimensional cultures of dermal papilla cells enhanced endothelial cell migration and angiogenesis in vitro, which may improve vascularization in tissue-engineered skin constructs.

In this study, researchers developed a method to create skin organoids using spinning bioreactors, facilitating efficient high-throughput drug screening, and found that Minoxidil activates the Wnt/beta-catenin signaling pathway in these models.

This study found that Quantitative Mass Spectrometry Imaging offers precise localization and quantification of active compounds in skin tissues, demonstrating benefits over traditional LC-MS in drug penetration studies.

Systemic mastocytosis may cause a type of hair loss called cicatricial alopecia.

This study demonstrated that implanting μm-scale full-thickness columns of human skin tissue into immunodeficient mice restored key features of normal human skin, suggesting potential for human wound repair with minimal donor site morbidity.

This study found that combining laser ablation with nanoparticulate drug formulations effectively enhanced the skin and follicular delivery of hydrophilic drugs like minoxidil and minocycline in preclinical models.

This article evaluates reflectance confocal microscopy features of scalp melanoma but reports no new clinical results, suggesting further investigation is needed.

This study used advanced optical imaging techniques to investigate nanoparticle and dye penetration in human skin, finding that nanoparticles mainly resided in the stratum corneum and accumulated in skin folds and hair follicles, while highlighting that sunscreen-based nanoparticles appear unlikely to pose safety concerns.

This study introduced an innovative nanozyme system called MCP@G, which was shown to improve diabetic wound healing in rats by alleviating mitochondrial oxidative stress, enhancing fibroblast migration, and promoting blood vessel and hair follicle regeneration, offering a promising approach for treating challenging diabetic wounds.

In this study, researchers used a murine model of irritant contact dermatitis to reveal that hair follicle regions serve as key sites for neutrophil transepidermal migration, which requires MMP-9 expression stimulated by dermal monocytes.

This study developed a tissue-engineered model of innervated skin, allowing for examination of how epidermis and capillaries affect nerve growth and offering a tool for further research on skin-related processes.

This correspondence highlights a case of intradermal minoxidil injection in a patient but does not report new research findings.

This study reviewed preclinical and clinical research and found that AFL-assisted topical drug delivery is considered safe and effective, enhancing drug efficacy, reducing treatment time and pain, and improving cosmetic and safety outcomes, but larger clinical trials are needed to confirm these benefits.
