Abstract
Addressing the challenges in managing ischemic tissue repair and remodelling remains a prominent clinical concern. Current research is heavily concentrated on identifying innovative cell-based therapies with the potential to enhance revascularization in patients affected by these diseases. We have previously developed and validated a manufacturing process for human umbilical cord mesenchymal stromal cells (UC-MSCs)-based cell therapy medicinal product, according to Good Manufacturing Practices. In this study, we demonstrate that these UC-MSCs enhance the proliferation and migration of endothelial cells and the formation of capillary structures. Moreover, UC-MSCs and endothelial cells interact, allowing UC-MSCs to acquire a perivascular cell phenotype and consequently provide direct support to the newly formed vascular network. This characterization of the proangiogenic properties of this UC-MSCs based-cell therapy medicinal product is an essential step for its therapeutic assessment in the clinical context of vascular regeneration.
