This review examines the evolving understanding of lymphatic vessel development, emphasizing new cellular mechanisms and lineage diversity, while discussing experimental methods and identifying key knowledge gaps.

This study observed that activin A and its antagonist follistatin influence the differentiation of inner ear hair cells by regulating the expression of the transcription factor ATOH1.

This study found that combining adipose-derived mesenchymal stromal cells with meglumine antimoniate reduced lesion size and parasite load in mice with leishmaniasis, suggesting potential for improved treatment.

This study observed that stem cells from the hair follicle dermis share similarities with bone marrow-derived mesenchymal stem cells and have potential to form neural-like cells under specific conditions.

This study found that thymus transplantation in athymic mice resulted in T-cell-driven hair follicle depigmentation and loss, without multiorgan autoimmune disease, highlighting mechanisms of tissue-specific tolerance.

This review examines the potential of regulatory T cell-based therapies to transform treatment across various medical specialties by promoting immune tolerance and tissue repair, but it reports no new clinical results.

This review discusses the role of regulatory T-cells in tissue repair and regeneration across various organs and reports no new clinical results.

This study found that mouse skin CD4(+) memory T cells are in equilibrium with the circulation under steady state but increase in specific clusters in response to infection or inflammation.

This review covers recent findings on stem cell plasticity under normal and cancerous conditions but presents no new experimental results, highlighting implications for regenerative medicine and cancer treatments.

This study demonstrated that a c-Kit-CreER-driven mouse model confirms melanocyte stem cells as a genuine source of melanoma, paralleling human melanoma in heterogeneity and gene signatures.

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 review addresses the role of skin-resident adult stem/progenitor cells in skin homeostasis, disease, and cancer development, and reports no new research results.

This review discusses how recent studies use models and experiments to understand immune system signaling, but it reports no new clinical findings; the authors suggest strategies for improving these models.

This study suggests that the presence and arrangement of plasmacytoid dendritic cells can help distinguish chronic cutaneous lupus erythematosus from other types of scarring alopecia.

This clinical case study describes an aggressive squamous cell carcinoma developing within a giant epidermal cyst on the abdomen.

In this study, subcutaneous recombinant human IL-12 showed a 43% partial response rate in early-stage mycosis fungoides patients refractory to previous treatments, with generally mild to moderate adverse events reported.

This study found that lower expression of Septin4 is significantly associated with worse outcomes in colon cancer, and its interaction with BAX in DOX treatment suggests its potential in targeted therapy.

This study found that macroscopic vesiculobullous lesions with epidermal devitalization in dogs are part of the clinical spectrum of canine cutaneous epitheliotropic T-cell lymphoma.

This study explored peripheral blood immune dysregulation in alopecia areata through single-cell analyses, identifying systemic changes linked to disease severity and key signaling roles for monocytes, NK cells, and memory T cells, suggesting potential therapeutic targets.

In this narrative review, researchers outlined the role of T cells in the autoimmune pathogenesis of alopecia areata and highlighted ongoing research into therapeutic pathways, beyond current JAK inhibitors, aimed at developing new treatments for the disease.

This study found that injecting xeno-free, three-dimensional cell masses from human adipose-derived stem cells improved blood perfusion and preserved limb function in mice without causing tumors or toxicity, suggesting potential for treating severe ischemic diseases.

This case report describes a rare aggressive variant of squamous cell carcinoma on the scalp of a non-immunosuppressed older male, highlighting its high biological risk for metastasis and poor outcomes.

This review examines the origins and mechanisms of tumor initiation in common skin cancers, but does not present new experimental findings; it emphasizes the need for further research on cancer stem cells.

This review discusses the multifaceted roles of regulatory T cells in cutaneous wound healing and highlights potential therapeutic strategies targeting these cells to enhance wound repair in chronic and diabetic wounds, but reports no new clinical results.

This review discusses the heterogeneity of Tregs in normal and tumor environments, emphasizing the complexity of targeting tumor-resident Tregs while maintaining systemic immune tolerance, but reports no new findings.

This study discusses how different modes of regulated cell death in keratinocytes affect skin stem cell niches, and their role in skin inflammation, injury repair, and cancer, based on findings from human dermatological conditions and experimental mouse models.

This study demonstrated that disrupting EGFR signaling in mice leads to immune sensitivity compromising the hair follicle's protective environment, but JAK1/2 inhibition can restore this immune privilege and stimulate hair growth, suggesting a potential therapy for scarring hair loss diseases like cicatricial alopecia.

This study constructed a comprehensive atlas of prenatal human skin, revealing that innate immune cells, such as macrophages, play a crucial role in skin morphogenesis by interacting with non-immune cells, influencing hair follicle formation and angiogenesis beyond their traditional immune functions.

This report highlights the usefulness of specific diagnostic procedures, including penile/preputial cytology and transabdominal ultrasonography, in diagnosing cryptorchidism and Sertoli cell tumors in dogs with generalized skin conditions.

This case study of a young Palestinian woman illustrates the diagnostic and treatment challenges of ovarian steroid cell tumors, highlighting the importance of detailed examination when hormonal therapy fails.
