Abstract

The aim of this study is preconditioning of hBM-MSCs using curcumin modified nanomembrane to optimize therapy of hepatic fibrosis and preventing its recurrence.

Methods: The nanomembrane was prepared by electrospinning technique and characterized using conventional method (cur^- nanoscaffold and cur⁺ nanoscaffold). Kinetic release of curcumin was also measured by spectrophotometry. MSCs were isolated from human bone marrow (hBM-MSCs) and cultured on the both nanoscaffolds.

We evaluated the in-vivo effect of hBM-MSCs from both nanoscaffold cultures (cur^- nanoscaffold/hMSCs and cur⁺ nanoscaffold/MSCs) on liver fibrosis from its effective and preventive points and we assessed the mechanisms of these effects as in vitro studies as cell proliferation, its effect on hepatogenic differentiation, its effect on paracrine release of hBM-MSCs and in-vivo studying the effect on cell migration, survival, engraftment, fate of transplanted cells, modifying the fibrogenic and inflammatory microenvironments.

Results: The results of animal model showed that single injection of preconditioning of hBM-MSCs using curcumin modified nanoscaffold ameliorate the fibrosis and prevent its recurrence until 24 weeks of therapy in contrast to improvement but not ameliorative effect of hBM-MSCs/ curcumin negative nanoscaffold which recurred progressively after 12 weeks of therapy. These effects of curcumin modified nanoscaffold were results from its highly efficacy on cell proliferation, in-vitro and in-vivo hepatogenic differentiation, increasing cell migration, engraftment and survival in the inflammatory microenvironment which was markedly improved by down regulation of inflammatory mediators and upregulation of anti-oxidant factors.

Conclusion: hBM-MSCs cultured on the prepared curcumin nanomembrane in this study is promising in regenerative therapy for ameliorating the hepatic fibrosis and to prevent its recurrence.

Keywords: MSCs, Curcumin/nanoscaffold, hepatic fibrosis model, ameliorative effect, preventive effect
