Abstract EN

Several studies have demonstrated a potential interaction between mesenchymal stem cells (MSCs) and saccular aneurysms.

In this study, we sought to determine whether allogenic bone marrow-derived MSCs had the ability to prevent aneurysm formation in a known rabbit elastase aneurysm model.

MSCs were injected intravenously in experimental rabbits at the time of surgical creation and two weeks postcreation and compared with control rabbits receiving vehicle injection.

Angiography was used to compare aneurysm measurements four weeks postcreation, and aneurysms were harvested for histological properties.

Serum was collected longitudinally to evaluate cytokine alterations.

Serum from control animals was also utilized to perform in vitro tests with MSCs to compare the effect of the serologic environment in animals with and without aneurysms on MSC proliferation and cytokine production.

While aneurysm morphometric comparisons revealed no differences, significant cytokine alterations were observed in vitro and in vivo, suggesting both anti-inflammatory and proinflammatory processes were occurring in the presence of MSCs.

Histological analyses suggested that tunica intima hyperplasia was inhibited in the presence of MSCs.
