Acute respiratory distress syndrome (ARDS) is a life-threatening inflammatory lung condition associated with significant morbidity and mortality. Unfortunately, the current treatment for this disease is mainly supportive. Mesenchymal stem cells (MSCs) due to their immunomodulatory properties are increasingly being studied for the treatment of ARDS and have shown promise in multiple animal studies. The therapeutic effects of MSCs are exerted in part in a paracrine manner by releasing extracellular vesicles (EVs), rather than local engraftment. MSC-derived EVs are emerging as potential alternatives to MSC therapy in ARDS. In this review, we will introduce EVs and briefly discuss current data on EVs and MSCs in ARDS. We will discuss current literature on the role of MSC-derived EVs in pathogenesis and treatment of ARDS and their potential as a treatment strategy in the future.

Background: The hypobaric hypoxic atmosphere can cause adverse reactions or sickness. The purpose of this study was to explore the preventive effect and mechanism of human umbilical cord mesenchymal stem cells (hUC-MSCs) on acute pathological injury in mice exposed to high-altitude.
Methods: We pretreated C57BL/6 mice with hUC-MSCs via the tail vein injection, and then the mice were subjected to hypobaric hypoxic conditions for five days.
Stem cells prevent long-term deterioration of renal function after renal artery revascularization in a renovascular hypertension model in rats.

Partial stenosis of the renal artery causes renovascular hypertension (RVH) and is accompanied by chronic renal ischemia, resulting in irreversible kidney damage. Revascularization constitutes the most efficient therapy for normalizing blood pressure (BP) and has significant benefits for renal function; however, the tissue damage caused by chronic hypoxia is not fully reversed. Mesenchymal stem cells (MSCs) have produced discrete results in minimizing RVH and renal tissue and functional improvements since the obstruction persists.

The anti-inflammatory role of miR-23b-3p (miR-23b) is known in autoimmune diseases like multiple sclerosis, systemic lupus erythematosus, and rheumatoid arthritis. However, its role in sepsis-related acute lung injury (ALI) and its effect on macrophages in ALI remain unexplored. This investigation aimed to evaluate miR-23b's therapeutic potential in macrophages in the context of ALI.

Gastric cancer mesenchymal stem cells (GC-MSCs) are a crucial component of the gastric cancer microenvironment, exerting a pivotal influence on the formation of a suppressive immune microenvironment and the progression of gastric cancer. In this study, we utilized GC-MSCs to co-culture peripheral blood mononuclear cells (PBMCs) obtained from both gastric cancer patients and healthy individuals in a proportionate manner by direct cell-to-cell contact. Our findings reveal that co-culture of GC-MSCs with PBMCs led to a notable reduction in CD8 T cells percentages and an increase in surface PD-1 expression levels on CD8 T cells.
