This review outlines the development, applications, and challenges of microneedle-based drug delivery from 2000-2019, particularly highlighting fabrication techniques, but reports no new clinical results.

In this study, topical application of fibroblast growth factors was found to promote hair growth by inducing and prolonging the anagen phase in telogenic C57BL/6 mice, suggesting potential as hair growth-promoting agents.

This study found that prolactin is a key regulator of keratin expression in human hair follicles, enhancing specific keratin types and influencing epithelial stem cell-associated keratins.

In this study, topical CUR61414 was effective in inhibiting basal cell carcinomas in mice, but no clinical activity was observed in human trials.

This study reported that using condensed nanofat combined with fat grafts significantly improved the aesthetic and functional aspects of atrophic facial scars in 20 patients, as assessed by both patients and plastic surgeons using the Patient and Observer Scar Assessment Scale.

This review discusses hormone replacement therapy for women with premature ovarian insufficiency, strongly recommending it for symptom relief and bone protection, but notes a lack of evidence on optimal types and doses.

This study found that amplifying Wnt signaling, either genetically or through topical application of liposomal Wnt3a, improved skin wound healing in a mouse model.

This review discusses the causes, clinical presentation, and management of anagen effluvium, emphasizing its psychological impact and the need for empathy and practical support, but reports no new results.

This review examines beta-catenin's role in stem cell renewal, lineage selection, and tumor formation in the epidermis and reports no new experimental findings.

This review discusses the potential of adipose-derived tissue components like nanofat and stem cells for aesthetic rejuvenation, covering their use in hair growth, scar reduction, and more, without reporting new clinical results.

This review discusses recent findings on hair follicle morphogenesis and regeneration, focusing on molecular signals and stem cells, and suggests that understanding these processes may aid in developing new strategies for wound healing.

This study found that RANK-RANKL signaling regulates hair renewal and epidermal homeostasis in mice, revealing its role in initiating hair growth cycles and maintaining skin cell activity.

This study found that AR/VDR-targeted agonist hormone therapy can inhibit cell viability in HR2-av triple-negative breast cancer cell lines through multiple mechanisms and may enhance the effects of chemotherapy.

This study found that activating Nrf2 in human hair follicles significantly reduced oxidative stress, lipid peroxidation, and protected against hair growth inhibition, suggesting a protective role for Nrf2 against redox insult in this context.

This review discusses the development and application of multiphoton microscopy in dermatology, highlighting its advantages and potential future research directions without reporting new clinical results.

This guide reviews the biology of sebaceous glands and their evaluation methods, emphasizing their roles beyond lipid production in skin health and disease, and reports no new research results.

This review discusses the role of miRNA/mRNA regulatory networks in skin development, epidermal homeostasis, and tissue remodeling, and suggests potential for miRNA-based therapies in treating skin conditions, but reports no new clinical results.

This article discusses the role of neurohormones and neuropeptides in hair follicle pigmentation and outlines promising neuroendocrinological strategies to address greying and damage, but reports no new clinical results.

This review discusses recent advances in scarless wound healing, focusing on strategies to create pro-regenerative scaffolds for repairing damaged skin, and reports no new clinical results.

In this study, mouse sweat gland development relied on a regulatory sequence initiated by Wnt/β-catenin signaling, and disruptions in Wnt, Eda, or Shh pathways led to distinct developmental failures.

In this study, miR-218-5p was found to enhance hair shaft growth and positively regulate the Wnt signaling pathway by targeting SFRP2 during skin and hair follicle development.

In this study, ectopic Wnt10b-mediated β-catenin activation in hair follicles resulted in larger regenerating anagen hair structures, an effect modulated by the Wnt inhibitor DKK1.

This study found that Brg1, a chromatin-remodeling enzyme, plays a critical role in hair regeneration and early epidermal repair by regulating bulge stem cells through a Brg1-Shh interaction.

This review examines the role of retinoic acid synthesis in hair follicles and sebaceous glands, focusing on its localization and function during normal and disease states, but reports no new results.

This study suggests that Botox injections may increase hair count and reduce hair loss in men with androgenetic alopecia, potentially through increased blood flow and oxygen to the scalp.

This study found that transgenic mice expressing human keratin K8 in the epidermis showed increased progression of skin lesions toward malignancy, suggesting a role for K8 in the development of invasive skin cancer.

This review discusses the typical wound healing process in skin and the oral cavity, and emphasizes the research focus on achieving scarless healing in adult skin, but reports no new clinical results.

In this study, mice exposed to prolonged space conditions demonstrated skin atrophy, altered hair follicle cycles, and significant changes in the gene expression associated with skin muscle health.

This article reviews emerging treatments for androgenetic alopecia, including topical 5-alpha-reductase inhibitors and prostaglandin modulators, but reports no clinical results and calls for further efficacy evidence, especially for PRP.

This study identified chemokine receptor ligands cxcl10 and cxcl11 as new hair-specific transcriptional targets of the Eda pathway, suggesting chemokine signaling plays a role in primary hair follicle patterning.
