Cutaneous photoaging, induced by chronic exposure to ultraviolet (UV) radiation, typically manifests as alterations in both the physical appearance and functional properties of the skin and may predispose individuals to cancer development. Recent studies have demonstrated the reparative potential of exosomes derived from mesenchymal stem cells in addressing skin damage, while specific reports highlight their efficacy in ameliorating skin photoaging. However, the precise role of exosomes derived from human hair follicle mesenchymal stem cells (HFMSC-Exos) in the context of cutaneous photoaging remains largely unexplored.

Impaired wound healing affects the life quality of patients and causes a substantial financial burden. Hydrogen-rich medium is reported to have antioxidant and anti-inflammatory effects. However, the role of hydrogen-rich saline (HRS) in cutaneous wound healing remains largely unexplored, especially by metabolomics.

Tissue clearing combined with high-resolution confocal imaging is a cutting-edge approach for dissecting the three-dimensional (3D) architecture of tissues and deciphering cellular spatial interactions under physiological and pathological conditions. Deciphering the spatial interaction of leptin receptor-expressing (LepR) stromal cells with other compartments in the bone marrow is crucial for a deeper understanding of the stem cell niche and the skeletal tissue. In this study, we introduce an optimized protocol for the 3D analysis of skeletal tissues, enabling the visualization of hematopoietic and stromal cells, especially LepR stromal cells, within optically cleared bone hemisections.

Chronic wounds and injuries remain a substantial healthcare challenge, with significant burdens on patient quality of life and healthcare resources. Mesenchymal stromal cells (MSCs) present an innovative approach to enhance tissue repair and regeneration in the context of wound healing. The intrinsic presence of MSCs in skin tissue, combined with their roles in wound repair, ease of isolation, broad secretory profile, and low immunogenicity, makes them especially promising for treating chronic wounds.

Growing scientific evidence suggests a strong interconnection between inflammatory skin diseases and osteoporosis (OP), a systemic condition characterized by decreased bone density and structural fragility. These conditions seem to share common pathophysiological mechanisms, including immune dysregulation, chronic inflammation, and vitamin D deficiency, which play a crucial role in both skin and bone health. Additionally, the roles of gut microbiota (GM) and epigenetic regulation via microRNAs (miRNAs) emerge as key elements influencing the progression of both conditions.
