This review discusses current stem cell technologies, their potential therapeutic uses, and imaging techniques for tracking transplanted cells, without reporting new experimental results.

This review examines the potential of mesenchymal stem/stromal cells in treating and possibly preventing allergic diseases, and reports no new clinical results.

Men are more likely to have larger basal cell carcinomas and squamous cell carcinomas, while women have more superficial basal cell carcinomas and tumors on their legs and central face.

This study discusses how redox imbalance, specifically through reduced Insulin-like Growth Factor-1 mediated by the transcription factor JunB and sphingolipid metabolism changes, contributes to skin aging by depleting stem cell pools and altering the extracellular matrix, ultimately impacting skin integrity and function.

This article reviews the evolution of hair restoration surgery, discusses a specific technique used at the authors' center, and suggests possible future innovations, but it reports no new clinical results.

The document concludes that early diagnosis and treatment are crucial for managing skin diseases in ferrets.

This study observed that multiple familial trichoepitheliomas commonly presented with a cribriform histopathological tumor pattern, differentiating them from solitary trichoepitheliomas.

This review highlights that current in vitro models often fail to replicate the physiological oxygen levels experienced by different skin cell types, which could affect redox states and functions, potentially accelerating skin aging.

This study found that by using an automated system to analyze skin histology, 108 structural features were significantly affected by age, and it identified four new aging biomarkers and notable sex-based differences in skin aging.

No results are provided in this article as it lacks an available abstract, making it unclear what effects apremilast and tofacitinib have in a humanized mouse model of alopecia areata.

This review discusses the causes, diagnosis, and treatment of pediatric alopecia, emphasizing early diagnosis and considering holistic approaches, but reports no new clinical results.

In this study, increased protein intake during modified fasting nearly eliminated hair loss observed in patients with significant weight loss and negative nitrogen balance.

This scoping review evaluates the connection between hypoxia and declining sex hormonal signaling in middle-aged individuals, proposing a "middle-aging hypovascularity hypoxia hypothesis" as a potential mechanism influencing age-related diseases, with implications for developing strategies to maintain healthspan.

Plant extracts might help control stem cell growth for medical use.

In this study on a mouse model of vitiligo, NB-UVB/ADSC combination therapy improved oxidative stress and calcium homeostasis, but the protective effect was reversed by inhibiting Nr2 signaling.

In this study, transplantation of rat hair follicle stem cells significantly improved sciatic nerve regeneration and muscle function in nerve-injured rats.

This study suggests that the CXCL8 gene may regulate cashmere fineness in Liaoning cashmere goats, providing new insights into the cellular mechanisms of cashmere growth and quality.

This study identified known and potential novel adverse events, such as squamous cell carcinoma and dehydration, for vismodegib, underlining the importance of monitoring especially in the first two months of treatment.

This study analyzed gene expression data to identify key genes involved in severe forms of alopecia areata, discovering four immune monitoring genes (LGR5, SHISA2, HOXC13, S100A3) with potential for early diagnosis and better understanding of the disease's biological mechanisms.

This study found that exposing adult esophageal epithelial cells to skin stroma can induce them to transition toward a hair follicle identity, with HIF1a playing a crucial role in this conversion process.

This study identified melanoma, squamous cell carcinoma, basal cell carcinoma, psoriasis, and atopic dermatitis as top priority topics for dermatological clinical practice guideline development in the Netherlands.

This chapter discusses the concepts of regeneration and homeostasis, noting that in vertebrates, regeneration is limited to certain tissues like liver, blood, and bone.

This review summarizes current evidence on how beta-human papillomavirus and Merkel cell polyomavirus may contribute to the development of nonmelanoma and Merkel cell skin carcinomas, respectively, but it reports no new clinical findings.

Hidradenitis Suppurativa is a chronic skin condition best treated early with surgery for better outcomes and less recurrence.

This case report describes a middle-aged man with a growing scrotal mass, diagnosed as a benign proliferating trichilemmal tumor, which can mimic squamous cell carcinoma, highlighting the importance of correct diagnosis.

This study presented a case where eyebrow hair follicles transplanted in a patient undergoing radiotherapy survived, resulting in a satisfactory and symmetrical appearance.

This study found that hucMSC-EXOs delivered via intratympanic injection effectively target vestibular sensory tissues, significantly reducing gentamicin-induced balance issues and high-frequency hearing loss, with some measured outcomes surpassing those achieved with dexamethasone.

This study found that zebrafish with a mutation in the GDP-fucose biosynthesis gene exhibited enhanced and faster regeneration of mechanosensory hair cells, implicating the importance of this gene and Notch signalling regulation in hair cell regeneration mechanisms.

This study found that mange was the most common cause of alopecia in dogs, with cases being more prevalent during the summer and among dogs less than one year old.

This article provides industry updates on stem cell research and regenerative medicine from December 2019 and reports no new research findings.
