Umbilical cord mesenchymal stem cell exosomes alleviate necrotizing enterocolitis in neonatal mice by regulating intestinal epithelial cells autophagy

BACKGROUNDNecrotizing enterocolitis (NEC) is a severe gastrointestinal disease that affects premature infants. Although mounting evidence supports the therapeutic effect of exosomes on NEC, the underlying mechanisms remain unclear. AIMTo i

Outcomes of combined mitochondria and mesenchymal stem cells-derived exosome therapy in rat acute respiratory distress syndrome and sepsis

BACKGROUNDThe treatment of acute respiratory distress syndrome (ARDS) complicated by sepsis syndrome (SS) remains challenging. AIMTo investigate whether combined adipose-derived mesenchymal-stem-cells (ADMSCs)-derived exosome (EXAD) and ex

Exosomes from umbilical cord mesenchymal stromal cells promote the collagen production of fibroblasts from pelvic organ prolapse

BACKGROUNDPelvic organ prolapse (POP) involves pelvic organ herniation into the vagina due to pelvic floor tissue laxity, and vaginal structure is an essential factor. In POP, the vaginal walls exhibit abnormal collagen distribution and dec

Extracellular vesicles derived from mesenchymal stem cells mediate extracellular matrix remodeling in osteoarthritis through the transport of microRNA-29a

BACKGROUNDKnee osteoarthritis (KOA) is a common orthopedic condition with an uncertain etiology, possibly involving genetics and biomechanics. Factors like changes in chondrocyte microenvironment, oxidative stress, inflammation, and immune

‘iTEARS’ could help diagnose diseases by isolating biomarkers in tears

In ACS Nano, researchers report a nanomembrane system that harvests and purifies tiny blobs called exosomes from tears, allowing researchers to quickly analyze them for disease biomarkers. Dubbed iTEARS, the platform could enable more efficient and less invasive diagnoses for many diseases.

New strategy blocks chronic lung disease in mice

A new study from Washington University School of Medicine in St. Louis has uncovered a previously unknown role for exosomes in inflammatory respiratory diseases. The study has implications for finding new therapies. Exosomes are tiny compartments released from cells that carry different types of cargo, including inflammatory chemicals called cytokines that can drive lung disease.

Exosome treatment improves recovery from heart attacks in a preclinical study

Research in pigs shows that using the exosomes naturally produced from a mix of heart muscle, endothelial and smooth muscle cells — all derived from human induced pluripotent stem cells — yields regenerative benefits equivalent to the injected human induced pluripotent stem cell-cardiac cells.
