Chronic non-healing wounds are a common complication of diabetes, marked by impaired angiogenesis. This study explores how exosomes (Exo-miR-1248) from miR-1248-overexpressing adipose-derived stem cells enhance diabetic wound healing by modulating endothelial cell function. Adipose-derived stem cells were transfected with a lentivirus carrying miR-1248 to produce Exo-miR-1248, isolated via differential centrifugation.

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.

MicroRNA (miRNA) serves as an effective and viable biomarker for early diagnosis and monitoring of cancer disorders. It is highly expressed in tumor cells, including lung cancer, liver cancer and lymphoma. Herein, we propose a ratiometric electrochemical sensor for ultrasensitive detection of miRNA-21 using dual signal amplification, hybridization chain reaction and Exo III assisted-amplification.

Skin grafting techniques are widely used for large burns, trauma, and various acute and chronic wounds, contributing greatly to the repair of traumatic tissue. However, donor site repair and regeneration are often neglected, resulting in infection and delayed healing. Therefore, it is crucial to reduce the rate of donor site infection and improve the speed and quality of healing.

Inflammatory mediators tumor necrosis factor (TNF) and interleukin 1 beta (IL1β), primarily derived from hepatic macrophages in the liver, play a crucial role in the progression of nonalcoholic steatohepatitis (NASH). Meanwhile, intravenously injected exosomes are mainly distributed in the liver and predominantly taken up by hepatic macrophage. Herein, we aimed to evaluate the feasibility of targeted inhibition of TNF and IL1β expression in hepatic macrophages via exosomes as a potential therapeutic strategy for NASH.
