Core Tip

Core tip: Secretome of porcine vascular wall mesenchymal stromal cells (pVW-MSCs) induced an increase of glial cell number in swine and guinea pig-derived enteric ganglia. Co-treatment of enteric ganglia with lipopolysaccharide and conditioned medium promoted glial cell differentiation only in pigs. These data indicate an immune activation promoted by pVW-MSCs which could be more specific in higher mammals, suggesting a careful consideration of the animal models used in research studies on cell-based therapies.
