Abstract

Background: Schistosomiasis is an acute and chronic disease of the genus Schistosoma triggered by blood flukes. Schistosomiasis is a disease occurring in, or endemic to, tropical and subtropical regions. A new concept was implemented to deal with schistosomiasis from natural plant sources. Curcumin's common name is Turmeric. Curcumin has proven to be main active component in Curcuma longa L. and has a wide range of anti-phrastic effects. Previous studies have shown the role of bone marrow mesenchymal stem cells (BMSCs) therapy in hepatic fibrosis recovery.

Objective: The current study was, therefore, intended to examine therapeutic role of BMSCs and Turmeric in murine schistosomiasis mansoni.

Animals: Mice were divided into five groups: a negative control group (non-infected non-treated), a positive control group (infected non-treated), a BMSCs treated group; Turmeric treated group, and untreated group. BMSCs derived from male mice were injected intraperitoneally into female mice receiving S. mansoni cercariae through the subcutaneous route. Liver histopathology and immuno-histochemical examinations were evaluated.

Results: BMSCs intraperitoneal injection resulted in a significant reduction of liver collagen, granuloma size, and significant increase of OV-6 expression in the Schistosomiasis-treated mice group. There was overall improvement in pathological changes of the liver. Unfortunately, group IV showed a mild improvement in the granuloma size and fibrosis compared to corresponding BMSCs treatment group, although with vacuolated liver cells.

Conclusion and clinical relevance: BMSCs have a regenerative potential in liver tissue histopathology by decreasing liver fibrosis and granulomas. Turmeric, by contrast, could not be used as an anti-fibrotic, according to the findings.

Keywords: BMSCs; Histopathology; OV-6; Schistosoma mansoni; Turmeric.
