“…The secretome of MSC is shown to be a rich source of trophic factors to many other cells (Kabiri, F I G U R E 8 Morphology of Wharton's jelly-derived MSCs seeded on the scaffolds after 7 days, shown in two different magnification.

They can secrete multiple growth factors and proangiogenic cytokines such as VEGF, which, in turn, can recruit circulating progenitors of EC and SMC or induce the migration of more mature vascular cells in adjacent vessels(Watt et al, 2013).…”
