Abstract
Endothelial cells (ECs), as important constituent of blood vessel are crucial to maintaining vascular tone, and any dysfunction in ECs could lead to many diseases of the vascular system. Due to limited availability of human samples, most of our research has been limited to animal models. Induced pluripotent stem cells (iPSCs) due to their potential to differentiate into any cell type of the human body, including cells of the cardiovascular system, provide us with a great opportunity to study human vascular disease. This protocol describes an efficient, simple, and step-wise method to differentiate iPSCs to endothelial cells (iPSC-ECs) using small molecules and growth factors. Through the activation of WNT signaling pathway, iPSCs are differentiated towards a mesodermal lineage with the potential to generate endothelial progenitors. These progenitors are further stimulated with growth factors to generate endothelial cells (Figure 1A).
