Mesenchymal Stem Cells Reduce Inflammation while Enhancing Bacterial Clearance and Improving Survival in Sepsis

ABSTRACT: Expression data from Total RNA extracted from murine spleen. Sepsis was induced in C57Bl/6J mice by cecal ligation and puncture (CLP), followed 6 hours later by an intravenous injection of Mesenchymal Stem Cell (MSC) or saline. Twenty-eight hours after CLP, plasma, bronchoalveolar lavage (BAL) fluid and tissues were collected for analyses. Total RNA was extracted using Trizol (as per manufactures' instruction) followed by clean-up procedure using Qiagen RNA easy Prep (as per manufactures instructions) In the following study we hypothesized that mesenchymal stem cells (MSCs), which have documented immunomodulatory properties, would reduce sepsis-associated inflammation and organ injury in a clinically relevant model of sepsis. To identify the molecular changes associated with decreased inflammation in CLP-injured mice treated with MSCs, we analyzed the gene expression profiles from spleens collected at 28 hours from 4 animals per group: sham/saline, CLP/saline, and CLP/MSCs.

RATIONALE: Sepsis refers to the clinical syndrome of severe systemic inflammation precipitated by infection. Despite appropriate antimicrobial therapy, sepsis-related morbidity and mortality remain intractable problems in critically ill patients. Moreover, there is no specific treatment strategy for the syndrome of sepsis-induced multiple organ dysfunction. OBJECTIVES: We hypothesized that mesenchymal stem cells (MSCs), which have been shown to have immunomodulatory properties, would reduce seps  ...[more]
