Recent studies have shown that Sca-1(+) (stem cell antigen-1) stem/progenitor cells within blood vessel walls may contribute to neointima formation, but the mechanism behind their recruitment has not been explored. In this work progenitor were cultivated from mouse vein graft tissue and found exhibit increased migration when cocultured with smooth muscle (SMCs) or treated SMC-derived conditioned medium. This was associated elevated levels of chemokines, CCL2 (chemokine (C-C motif) ligand 2)...
