Adipose tissue-derived stromal cells' conditioned medium modulates endothelial-mesenchymal transition induced by IL-1β/TGF-β2 but does not restore endothelial function.

ABSTRACT:

Objectives

Endothelial cells undergo TGF-β-driven endothelial-mesenchymal transition (EndMT), representing up to 25% of cardiac myofibroblasts in ischaemic hearts. Previous research showed that conditioned medium of adipose tissue-derived stromal cells (ASC-CMed) blocks the activation of fibroblasts into fibrotic myofibroblasts. We tested the hypothesis that ASC-CMed abrogates EndMT and prevents the formation of adverse myofibroblasts.

Materials and methods

Human umbilical vein endothelial cells (HUVEC) were treated with IL-1β and TGF-β2 to induce EndMT, and the influence of ASC-CMed was assessed. As controls, non-treated HUVEC or HUVEC treated only with IL-1β in the absence or presence of ASC-CMed were used. Gene expression of inflammatory, endothelial, mesenchymal and extr
