This review discusses the role of scalp imaging techniques in trichology for researching drug delivery and toxicology, without presenting new clinical results.

Nanoparticles can be used to deliver drugs to hair follicles, potentially improving treatments for conditions like acne and alopecia, and could also be used for vaccine delivery and gene therapy.

This study explored peripheral blood immune dysregulation in alopecia areata through single-cell analyses, identifying systemic changes linked to disease severity and key signaling roles for monocytes, NK cells, and memory T cells, suggesting potential therapeutic targets.

Using tissue expanders for scalp reconstruction in patients with extensive Aplasia Cutis Congenita is effective and has minimal complications.

This review highlights the importance of recognizing neoplastic alopecia as a potential indicator of underlying metastatic neoplasia, as it may be mistaken for other scalp conditions like alopecia areata.

This study found that human umbilical cord-derived mesenchymal stromal cell-conditioned media was safe and positively affected hair regeneration in 86.6% of participants in a pilot study.

This study suggests that AT-ASCs significantly improve terminal and intermediate hair counts and hair caliber in androgenetic alopecia more than PRP, though with more side effects like headache and erythema.

This study found that radiation negatively impacts the survival and proliferation of fibroblasts on human dermis transplants, but hair follicle pores enhance cell viability even after irradiation.

This study demonstrated that intraoperative bioprinting using a bioink with human adipose-derived extracellular matrix and stem cells achieved successful reconstruction of full-thickness craniomaxillofacial skin defects in rats, promoting wound closure, adipogenesis, and hair follicle-like structure formation within two weeks.

This chapter reviews the combined use of platelet-rich plasma and microneedling for cosmetic enhancement but reports no clinical results; the authors highlight existing uses and suggest potential synergistic benefits in dermatology.

This study found that the ethyl acetate extract of Fagraea berteroana fruits and its fraction FEAE-F0 promoted cell proliferation and modulated gene expression in hair follicle cells, suggesting potential for hair growth stimulation.

In this study, both platelet-rich plasma gel and 1% phenytoin cream showed comparable results for wound healing in diabetic foot ulcers in rats, with PRP providing slightly advanced histological improvements; however, the differences were not statistically significant.

This review highlights the roles of key transcription factors and signaling pathways in regulating olfactory epithelium regeneration, discussing recent advances in single-cell and spatial transcriptomics as well as organoid models to enhance understanding of olfactory regeneration mechanisms.

This case report documents a rare instance of a trichilemmal cyst occurring on the plantar surface of the foot, highlighting the necessity of histological examination for accurate diagnosis when clinical or radiological presentations are atypical.

The researchers observed that in cichlid fishes with different dental structures, tooth replacement accelerated more than three times following tooth extraction, alongside distinct changes in gene expression and cellular interactions over one week, providing insights into tooth regeneration mechanisms in vertebrates.

This study evaluated 23 cases of MRKH syndrome undergoing neo-vaginal reconstruction using islanded pudendal thigh flaps, finding a 100% flap survival and patency rate, along with satisfactory functional and aesthetic outcomes despite minor issues like hair growth in some patients.

This review discusses the multifaceted roles of regulatory T cells in cutaneous wound healing and highlights potential therapeutic strategies targeting these cells to enhance wound repair in chronic and diabetic wounds, but reports no new clinical results.

This study found that a mesenchymal stromal cell-derived regenerative extracellular matrix (rECM) significantly accelerated wound closure and improved healing in diabetic mice, also enhancing nerve and blood vessel formation compared to controls.

This article reviews the regenerative benefits of platelet-rich plasma in various medical fields, particularly in dermatology and aesthetic medicine, without presenting new clinical data.

This review suggests that although hydrolyzed collagen peptides with certain supplements may improve skin elasticity and joint function, evidence for collagen's anti-aging and regenerative benefits remains inconsistent.

This review discusses the spectrum of lupus erythematosus conditions, specifically focusing on the different forms of Cutaneous Lupus Erythematosus, and reports no clinical results.

In this review, retinoids are highlighted as promising agents for promoting scarless skin regeneration by coordinating cellular and molecular processes that suppress fibrosis, enhance re-epithelialization, promote angiogenesis, and enable hair follicle formation, potentially advancing functional skin repair.

This systematic review found that platelet-rich plasma significantly improved hair density and count in androgenetic alopecia patients compared to controls, with minimal adverse effects reported.

This review explores the potential of microneedling as a drug delivery system for treating melasma, focusing on its mechanisms, safety, efficacy, and clinical advantages over conventional therapies like hydroquinone and lasers.

In this study, oral minoxidil treatment significantly increased serum VEGF levels and improved hair growth measures compared to a control group, suggesting its potential as an effective approach for promoting hair regrowth in androgenetic alopecia.

This study developed a degradable and bioactive citrate-based polyurethane adhesive that achieves rapid and strong tissue adhesion, exhibiting improved bonding strength in wet environments, biocompatibility, biodegradability, and hemostatic properties, with potential to enhance wound healing by promoting angiogenesis.

This review discusses advancements in regenerative medicine for hair loss treatments, highlighting stem cell techniques for rejuvenating or creating hair follicles, but provides no new clinical results.

This study found that keratin filament networks in SG1 cells of mice undergo dynamic changes during cornification, impacting the barrier function of the stratum corneum.

This study demonstrated that in genetic mouse models, the calcium sensor Stim1, not Stim2, is essential for sweat secretion in sweat glands.

This study found that a water-soluble peptide from chicken egg yolk, named Hair Growth Peptide, improved hair growth in mice and female pattern hair loss through increased IGF-1 and VEGF production.
