ABSTRACT
INTRODUCTION:
Endothelial cells (EC) can be generated from porcine-induced pluripotent stem cells (piPSC), but poor efficiency in driving EC differentiation hampers their application and efficacy. Additionally, the culture of piPSC-derived EC (piPSC-EC) on three-dimensional (3D) scaffolds has not been fully reported yet. Here, we report a method to improve the generation of EC differentiation from piPSC and to facilitate their culture on 3D scaffolds, providing a potential resource for in vitro drug testing and the generation of tissue-engineered vascular grafts.METHODS:
We initiated the differentiation of piPSC into EC by seeding them on laminin 411 and employing a three-stage protocol, which involved the use of distinct EC differentiation media supplemented with CHIR99021, BMP4, VEGF, and bFGF.RESULTS:
piPSC-EC not only expressed EC markers such as CD31, VE-cadherin, and von Willebrand factor (vWF) but also exhibited an upregulation of EC marker genes, including CD31, CD34, VEGFR2, VE-cadherin, and vWF. They exhibited functional characteristics similar to those of porcine coronary artery endothelial cells (PCAEC), such as tube formation and Dil-Ac-LDL uptake. Furthermore, when cultured on 3D scaffolds, piPSC-EC developed a 3D morphology and were capable of forming an endothelial layer and engineering capillary-like networks, though these lacked lumen structures.CONCLUSION:
Our study not only advances the generation of EC from piPSC through an inhibitor and growth factor cocktail but also provides a promising approach for constructing vascular network-like structures. Importantly, these findings open new avenues for drug discovery in vitro and tissue engineering in vivo.
