Differential angiogenic pathways

Fig. 1 Bone marrow and peripheral blood stem cells. (A) Example of a bone marrow-derived MSC and its potential to differentiate into various lineages. Although not depicted in this figure, MSCs also have the potential to differentiate into vascular endothelial cells and promote angiogenesis for vascular repair [19,20]. (B) Differentiation pathway of CD34 peripheral blood stem cells from a hematopoietic stem cell lineage, which can serve to become endothelial cells within the vasculature and possess greater pro-angiogenic effects. Both figures reprinted from [21] and [22], respectively, with permission.
