Abstract

BACKGROUND: Intra-peritoneal adhesions (IPAs) common occurre in post abdominal surgical. Athough many methods have been developed for controlling IPAs, including mesenchymal stem cells (MSCs) application, however, there is none completely preventing in due to the mesothelial structure may promote the prolonged inflammations leading. Nevertheless hypoxia-MSCs (H-MSCs) have more potent in controlling the inflammation than normoxia-MSCs (N-MSCs) by releasing several anti-inflamation particularly IL-10, however the H-MSCs application to inhibit IPAs remain unclear.

AIM: The aim of this study was to investigate the effectiveness of H-MSCs in preventing the AIPs event by releasing IL-10 on the ileum abrasion sutured omental patch as the animal model of peritoneal adhesion.

METHODS: Using 24 IPAs animal model were randomly divided into 4 groups: Sham (Sh), Control (C), H-MSCs at high dose (T1) and H-MSCs at low dose (T2). H-MSCs were incubated under hypoxic conditions (5% O₂), 37Â°C and 5% CO₂ for 24 hours. The expression level of IL-10 was performed using RT-PCR analysis. The macroscopic appearance of IPAs was evaluated using Nairâ€™s scale base on the absence/presence of adhesion, whereas the microscopic by Zuhlkeâ€™s scale at Hematoxylin and eosin (H&E) staining.

RESULTS: This study showed a significanly increase in IL-10 expression (p < 0.05) at all T groups. In line with this, we also found a significant difference in IPAs between T groups and Control as well as a Sham (p < 0.05) either in the macroscopic or microscopic analysis.

CONCLUSION: H-MSCs has a robust ability in inhibiting severe IPAs characterized by the decreased of adhesion formation and the enhanced expression of IL-10.
