This study found that specialized nipple epidermis in mice is maintained by the repression of TGFβ signaling through estrogen, which highlights the role of hormonal regulation in epidermal maintenance.

In this study, researchers using single nuclei RNA-sequencing found that fibroblasts in deeper layers of mouse skin expressed higher levels of pro-inflammatory genes post-wounding compared to other cells, highlighting their significant role in early inflammation and tissue repair processes.

This study discusses the epithelial-immune microenvironment in chronic skin diseases, such as psoriasis and atopic dermatitis, and highlights current and future treatment strategies targeting inflammatory loops within these diseases.

This study reviewed the role of inflammasomes in autoimmune skin diseases, highlighting their contribution to the pathogenesis of conditions such as vitiligo, alopecia areata, and psoriasis, and suggesting that targeting inflammasome dysregulation may offer new therapeutic options.

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 revealed key cellular dynamics and interactions during early embryonic mouse skin development, highlighting complex transitions from precursor states to diverse multilayered structures.

This study revealed that Vav2 and Vav3 play roles in regulating hair follicle bulge stem cells in normal conditions and cancer stem cell activation and remodeling in mice.

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 report describes a rare case of severe combined immunodeficiency caused by a FOXN1 gene variant, complicated by Epstein-Barr virus infection and high-grade B-cell lymphoma, leading to the infant's death despite treatment efforts.

Different stem cells have benefits and challenges for tissue repair, and more research is needed to find the best types for each use.

In this study, researchers found that Elastic Net DNA methylation clocks are not accurate for distinguishing between individuals or identifying health markers, but measuring biological "noise" in stable cytosines may serve as a potential biomarker of aging and disease.

This study found that stem cells can temporarily act as non-professional phagocytes during hair cycle regeneration by clearing apoptotic cells through a process requiring local lipids and retinoids for activation, providing insights into their dual role in maintaining tissue integrity.

In this study, overexpression of miR-29 in mice led to aging-related phenotypes and early lethality, demonstrating its significant role in driving aging processes.

This study found that gelatin sponges used as scaffolds in rats with deep wounds and periosteal defects enabled regeneration of diverse tissue types, including periosteum, skin, and appendages, highlighting the role of vascular niche formation.

This review discusses the role of dermal macrophages in stress-induced hair regeneration and reports no new clinical findings, highlighting the need for further research into macrophage dynamics for potential hair loss therapies.

This source reviews the role of exosomes in regenerative medicine, highlighting their ability to mediate cell communication and transport biomolecules to enhance or impair biological functions, with potential applications in tissue repair and regeneration.

This study observed that pantethine, a vitamin B5 precursor, attenuates tumor growth in immunocompetent mice by enhancing antitumor immunity, but its effect is limited by immune cell exhaustion over time.

In this study, CD4+ non-haematopoietic, skin-resident stem cell-like populations were identified in both murine and human epidermis, suggesting they may serve as potential basal cell carcinoma precursors.

In this study, researchers identified unique prenatal lymphocyte features in human fetal skin, including proliferative naive T cells and memory-like T cells, which may influence antigen and allergen responses in utero and infancy.

This study reports that a novel gain-of-function mutation in TMEM173, combined with polymorphisms in TMEM173 and IFIH1, results in a distinct clinical phenotype with features of SAVI, including alopecia and photosensitivity.

The document concludes that the skin is a complex organ providing protection, sensation, and healing, with challenges in treating conditions like itchiness.

This study found that vitamin D regulates cholesterol metabolism and may influence prostate cancer development through mechanisms affecting prostate cell growth and sex hormone metabolism.

In this study, researchers used patient-derived organoids to model metastasis in colorectal cancer and discovered that cancer cells temporarily switch to a wound-healing program, orchestrated by reduced EZH2 activity and YAP signaling, before spreading to new organs.
