This review found that vesicle-based therapies, including mammalian MSC-derived and plant-derived vesicles, consistently promote wound healing in preclinical models of thermal injury and may offer a safer alternative to live cell transplants.

This study found that exosomes derived from human umbilical cord mesenchymal stem cells helped preserve melanocyte function and mitigate stress-induced hair depigmentation in mice by activating the Nrf2-ARE antioxidant pathway under acute neurogenic oxidative stress.

In this study, researchers identified that the oncomodulin protein lineage, specifically the gene pvalb8, plays a crucial role in the development and function of auditory hair cells in zebrafish by promoting cell proliferation through the Wnt signaling pathway.

This review highlights the potential of microneedle technology in traditional Chinese medicine as a promising transdermal delivery system for skin diseases, showcasing improved efficacy and reduced side effects of TCM ingredients while discussing the challenges of its clinical application.

This review discusses recent advancements in microneedle technology for hair loss treatment, highlighting their ability to enhance drug delivery and improve hair follicle survival in transplantation, while also exploring their potential integration with tissue engineering to address regeneration challenges.

This study on C57BL/6 mice found that subcutaneous cholesterol injections significantly promoted hair regeneration by enhancing hair follicle stem cell proliferation, highlighting the role of the PKA-tyrosine hydroxylase-sympathetic nervous system pathway in this process.

This study identified the transcription factor Elf5 as a novel regulator of keratinocyte proliferation and differentiation in skin, with expression elevated in stem/progenitor cell populations, suggesting its potential role in determining cell fate during skin and hair development.

This study found that extracellular vesicles derived from hyaluronic acid-stimulated induced pluripotent stem cells significantly improved hair growth in a model of androgenetic alopecia in mice by enhancing Wnt/β-catenin signaling and regulating androgen receptor activity, showing comparable results to the commonly used treatment finasteride.

The zinc finger protein 3 in Arabidopsis thaliana reduces plant growth and root hair development.

This study found that exosomes from adipose mesenchymal stromal cells, particularly those carrying miR-122-5p, may enhance hair follicle regeneration in androgenic alopecia by targeting the TGF-β/SMAD3 axis.

This study found that platelet-rich plasma microneedles promoted hair regrowth in mice by facilitating angiogenesis and cell proliferation, showing promise for a minimally invasive hair regeneration treatment.

This study systematically characterized the nanomechanical properties of human hair, such as hardness and elastic modulus, across different ethnicities and treatment conditions using nanoindentation and scanning electron microscopy.

This study assessed whether the elemental composition of human hair could serve as a marker for kidney stones, cholelithiasis, hypertension, and diabetes, but it reports only variations in element content along hair regions.

Polyquaternium 7® builds up on hair, improving its look and feel, and AFM is good for measuring these changes.

This article discusses silicon in hair loss but provides no new research findings or clinical results.

In this study, the researchers found that a manual micrometer caliper is a reliable tool for planning hair transplant surgery and accurately measures the short axis of the hair shaft.

This study investigated the effects of different relaxer treatments on African-American hair, finding lab-made relaxer solutions caused less damage to hair topography than commercial systems.

This study discusses using SEM/EDX for elemental analysis of hair samples in forensic science but notes challenges in detecting certain trace elements from raw hair.

This study found that rebonding hair straightening treatments visibly damage the hair cuticle, causing surface erosion and cracks, as shown through Scanning Electron Microscopy analysis.

This study used novel methods to detect and map iodine concentrations in pig skin, finding iodine present in the coating, stratum corneum, and tissue around hair follicles.
