Mesenchymal stem cell treatment alleviates seawater drowning induced lung injury by inhibiting the TNFα/Snail/EMT pathway.

ABSTRACT:

Background

Seawater drowning (SWD) has been an escalating hazard in recent years. It can not only cause immediate death but can also inflict severe complications, such as acute lung injury (ALI), which greatly increases the mortality rate. Thus, investigating the mechanism of SWD induced lung injury and discovering effective treatments is of great importance. The aim of this study was to minimize the lethality and disability of SWD-ALI.

Methods

Using male C57BL/6 mice, we established a SWD induced ALI (SWD-ALI) model via the oral laryngoscopy endotracheal injection (LEI) of artificial seawater. We then administered mesenchymal stem cells (MSCs) via laryngoscopy endotracheal nebulized inhalation. We tested our hypotheses using pulmonary function tests, micro-computed tomograp
