This review discusses the use of derma rollers for cosmetic purposes and their potential in transdermal drug delivery by summarizing evidence on their design, efficacy, safety, and concerns from preclinical and clinical reports.

This study found that transethosomal gel loaded with propranolol hydrochloride prolonged drug release and increased peak plasma concentration compared to an oral tablet, suggesting a promising alternative for delivery.

This study found that restoring the skin microbiome significantly improved hair growth and skin condition in androgenic alopecia model mice by modulating the immune-inflammatory balance, highlighting the potential of bacterial-based therapies for hair loss.

This chapter reviews therapies for skin and corneal regeneration and hair loss, discussing various treatments but presenting no new research findings.

This chapter reviews adverse effects of anti-anginal and beta-blocker drugs, stating that starting a beta-blocker may temporarily affect driving ability, but it reports no new clinical findings.

This study found that intradermal injections of platelet-rich plasma were equally safe and effective for treating androgenetic alopecia, with higher platelet numbers possibly enhancing hair density and follicle diameter.

This study found that combining minoxidil 0.1% and dutasteride 0.01% applied topically after microneedling was significantly more effective than using dutasteride alone with microneedling in improving female pattern hair loss in 40 female patients.

This review examines the potential of plant-derived exosome-like nanovesicles in dermatology, highlighting their bioactive properties and discussing challenges to their clinical application, but does not provide new clinical results.

This source reviews the latest developments in hair transplantation for androgenetic alopecia, suggesting that while medical therapy alone remains unsatisfactory, surgical hair restoration is shown to be highly gratifying for male pattern hair loss.

This review examines the progression of hair restoration techniques from early methods to modern follicular unit transplantation and presents no new clinical results.

Sex steroids, especially progesterone, can slow down the growth of mouse melanoma cells.

In this study, onion (Allium cepa) extracts promoted hair growth in an alopecia model in mice, with the effect appearing unrelated to the presence of the polyphenol quercetin.

In this study, researchers found that quiescent stem cells resist immune attack due to downregulated antigen presentation, which may help explain the immune evasion of early cancer-initiating cells.

This review examines various skin pigmentation disorders, their causes, and potential treatments, detailing 25 plants, 4 marine species, and 17 clinically tested topical and oral medications for managing these conditions.

This study identified highly variable genes in mesenchymal stem/stromal cells that are linked to classic functions like development and inflammation response, suggesting their potential as markers for further potency studies.

Keratin 17 is important for hair and nail structure and affects pachyonychia congenita symptoms.

In this study, immobilized VEGF selectively captured endothelial cells under various shear stresses, suggesting its potential for promoting endothelialization in vascular grafts or implanted tissues.

This study found that the CDK4/6 inhibitor palbociclib may protect human hair follicles from the damaging effects of taxane chemotherapy by inducing G1 arrest in stem/progenitor cells.

This study found cell-specific variations in POMC mRNA and peptide expression in murine skin, suggesting that PC1 and PC2 convertases contribute to differential POMC processing.

This review discusses the unique advantages and challenges of microneedle arrays for vaccine and immunotherapy delivery but reports no new clinical results.

The study found that while a clinical protocol showed high specificity in detecting scrapie in goats, its low sensitivity suggests many cases might be missed if diagnosis is only based on clinical signs.

In this study, exosome-mimetic nanovesicles derived from neural progenitor cells promoted hair follicle regeneration in mice by activating the Wnt/β-catenin signaling pathway.

In this study, researchers investigated the penetration and cellular responses to nanoplastics in human skin models with compromised barriers, finding that nanoplastics can penetrate the skin, accumulate in cells, and trigger inflammatory responses through specific signaling pathways.

This study describes a new mouse model for vitiligo that mimics key clinical features such as skin depigmentation and CD8 + T cell infiltration, providing a useful tool for in-depth research and drug discovery.

In this study, researchers used transcriptomics and modeling to uncover previously unknown cell populations and marker genes in developing hair follicles, providing insights into early cell fate establishment and offering tools for further research on skin appendages.

This study found that the estrous cycle influences the effect of the δ-GABAAR agonist THIP in reducing binge drinking behavior in female mice, with receptor expression elevated during diestrus.

This study found that a lentiviral array of reporters can identify lineage-specific promoters and pathways in mesenchymal stem cell differentiation, aiding in the prediction of signaling pathway effects.

This source presents a comprehensive review of the literature on diabetes, highlighting the complex factors involved in its development and the importance of prevention, early diagnosis, and a multi-faceted treatment approach for effective management.

This study found that in skin blister healing, hair follicle development is compromised as stem cells repair wounds at the expense of morphogenesis gene expression.

In this study, inducible whole-body Acly-knockout mice revealed that ACLY is essential for skin homeostasis, as its deficiency led to increased sebum production and skin abnormalities, indicating a vital role for cytosolic acetyl-CoA synthesis in preserving skin barrier integrity and systemic lipid regulation.
