This review highlights the challenges in identifying histological features of adverse reactions to soft tissue fillers and emphasizes the need for increased awareness due to product uncertainty and delayed reactions.

This review discusses the origins of skin and esophageal cancers and reports no clinical results; it emphasizes the role of cyclooxygenase-2 in tumorigenesis and differentiation.

This study found that human hair follicle dermal cells, specifically dermal sheath cells, can serve as an alternative and potentially superior cell source for constructing the dermal component of bioengineered skin in both in vitro and in vivo settings.

This review summarizes the anatomy and physiology of the arrector pili muscle and discusses its potential role in hair loss disorders, reporting no new clinical results.

This study reviewed the current state of intralesional therapy for keratoacanthoma, finding that while methotrexate, 5-fluorouracil, and interferon alpha are common agents, guidelines are still needed, and histopathological confirmation is advised to prevent misdiagnosis with squamous cell carcinoma.

This study found that overexpression of the transcription factor NFIC may enhance the proliferation and differentiation of stem cells from the apical papilla, suggesting its potential role in dentin/root regeneration.

This article is a letter to the editor discussing hair graying and loss potentially induced by imatinib mesylate, but it does not provide new research results.

This study found that inhibiting mTORC1 activity with rapamycin increased both hair growth and pigmentation in human scalp hair follicles, suggesting a potential strategy for treating greying and hair loss.

In this study, adipose-derived stem cells from superficial adipose tissue showed higher regenerative potential, and more macrophages were found in superficial than deep adipose tissue, potentially influenced by skin microbiota.

This review explores the infundibulum's role and importance in skin diseases and emphasizes the need for further research into its biology and potential therapeutic targeting, but it presents no new findings.

This study found that TRPV1 activation in human scalp hair follicles inhibited hair shaft elongation, suppressed proliferation, and induced apoptosis, suggesting TRPV1 as a potential target for managing hair growth and epithelial disorders.

This article reviews advancements in hair restoration, highlighting improvements in surgical techniques and patient satisfaction, but reports no new clinical results.

This study found that plasma rich in growth factors (PRGF) as an adjuvant to follicular unit extraction (FUE) surgery may enhance hair graft performance and reduce post-surgical inflammation and pain in hair loss patients.

In this study, transverse sectioning of scalp biopsy samples showed higher diagnostic accuracy than vertical sectioning for noncicatricial alopecia, although both techniques are important for accurate diagnosis.

This study observed two cases of pigmented epithelioid melanocytoma suggesting potential differing origins: one from a hair follicle's outer root sheath and another from an intradermal nevus.

This study reports that despite rescuing neurulation and skin barrier defects, Grhl3 gene overexpression in mice leads to hearing impairment, hair loss, and other developmental abnormalities, highlighting low tolerance for Grhl3 dysregulation.

This review discusses the dual role of the Wnt/β-catenin pathway in mammalian tissue injury, highlighting its potential for both promoting regeneration and contributing to fibrosis, but presents no new findings.

This review summarizes how genetic studies using conditional β-catenin loss- and gain-of-function mice have advanced understanding of canonical Wnt signaling's role in embryonic development, adult stem cell maintenance, and cancer modeling.

This review discusses sex-based differences in immune responses, focusing on genetic, hormonal, and microbiome factors influencing infections like COVID-19, and reports no clinical results.

This review discusses circadian clock regulation in stem cells and its role in processes like neurogenesis, but reports no new results; the authors emphasize its significance in stem cell function across various tissues.

This review discusses recent advances in the therapeutic potential of exosomes for wound healing, highlighting their benefits and challenges but reports no new clinical results.

This review discusses the various roles of RANK signaling in bone remodeling, immune function, and epithelial differentiation, highlighting its potential involvement in cancer mechanisms; it reports no new clinical results.

This article discusses the etiology, clinical features, diagnosis, histopathology, and treatment of alopecia areata but reports no new clinical findings; it emphasizes the palliative nature of current treatments.

This review discusses the potential role of extracellular vesicles in modulating hair follicle dynamics and reports no new clinical results; future investigations may inform treatment strategies for skin disorders.

This report discusses the various causes and clinical assessment of madarosis, emphasizing the importance of recognizing and diagnosing associated vision or life-threatening conditions, without presenting new findings.

This article discusses various types of primary cicatricial alopecias and reports no new clinical results; it emphasizes the importance of accurate diagnosis for effective management.

This review discusses genome-wide association studies in dermatology, noting that variants linked to risk for 10 skin complex diseases have been identified, with potential implications for diagnostics and management; it reports no new clinical results.

This study found distinct gene expression patterns in the blood of alopecia areata patients, suggesting involvement of immune processes and new pathways like Wnt signaling and apoptosis in disease pathogenesis.

This study identified KRT82 as a significant Alopecia Areata risk gene, finding that rare damaging variants are linked to elevated immune cell infiltration around hair follicles in affected individuals.
