iCell Endothelial Cells, 11713
Product Overview
Endothelial cells are highly dynamic cells that form the inner lining of blood vessels. In addition to their structural role, endothelial cells regulate the passage of substances between the bloodstream and surrounding tissue. They also secrete mediators that influence vascular hemodynamics, inflammation, cell trafficking, and the remodeling and formation of new blood vessels. Endothelial cell dysfunction is associated with a variety of diseases including atherosclerosis, coronary artery disease, hypertension, and inflammatory disorders.
Derived from human iPS cells, FCDI’s iCell® Endothelial Cells provide a reliable, reproducible, and physiologically relevant source of cells for vascular disease modeling, drug screening, and vascular tissue engineering applications. Benefits include:
- >90% CD31+/CD105+ populations across lots and multiple passages
- VEGF-mediated proliferation, sprouting, migration, and invasion
- TNFα-mediated upregulation of adhesion molecules
- Thrombin-sensitive barrier function
- Acetylated LDL uptake
- Shear stress-induced alignment
- 2D and 3D capillary-like network formation
Broad Function and Application
Assayed as a pure culture or in co-culture with other differentiated cell types to recapitulate native tissue architecture, iCell Endothelial Cells enable a variety of novel applications:
- Vascular tissue engineering:
Decellularized organs Amenable to decellularized organ (e.g. kidney) scaffold approaches (Caralt et al., 2015) - Vascular tissue engineering:

Formation of 3D Cardiac Tri-Culture Microtissues
Three-dimensional multi-cellular systems containing iCell Cardiomyocytes or iCell Cardiomyocytes2, iCell Endothelial Cells and primary cardiac fibroblasts have the potential for greater physiological relevance, predictive power, and mechanistic insight than cardiomyocytes alone. For information on 3D systems, see the Application Protocol: Culturing and Assaying Calcium Transients of 3D Cardiac Tri-Culture Microtissues
Figure 1: Structure of 3D Cardiac Tri-culture Microtissues Over Time.
Microtissues were formed containing 5,000 or 10,000 total cells in S-bio 96-well plates. Compact, contracting microtissues were obtained by Day 4. (A) Panel of phase contrast 10X images of 5,000 cell tri-culture spheroids over time using the Incucyte S3. (B) Quantification of 5,000 cell tri-culture microtissue diameter. Each dot represents a microtissue. Mean and SEM are indicated. (C) Comparison of Day 14 microtissue diameter of 5,000 cell tri-culture microtissues with 10,000 cell tri-culture microtissues. Each dot represents a microtissue. Mean and SEM are indicated. (D) H&E staining of Day 14, 3D cardiac tri-culture microtissue formed with 10,000 total cells. Staining shows the absence of a necrotic core.
Figure 2: 3D Cardiac Tri-culture Microtissues Response to Beta Adrenergic Agonist Isoproterenol
(A) Chronotropic response: Control iCell Cardiomyocytes, 11713 only microtissues (CM) and tri-culture microtissues exhibit an increase in beat rate with increasing concentrations of isoproterenol. (B) Inotropic response: Control iCell Cardiomyocytes, 11713 only microtissues (CM) do not increase amplitude with increasing concentrations of isoproterenol. Tri-culture microtissues demonstrate a twofold increase in beat amplitude with increasing concentrations of isoproterenol.
Enhanced Inotropic Response when Plated in Tri-Culture
3D cardiac tri-culture microtissues containing iCell Cardiomyocytes or iCell Cardiomyocytes2, iCell Endothelial Cells and cardiac fibroblasts demonstrated a positive response to the inotropic compound isoproterenol, which is characteristic of mature cardiomyocytes. For information on 3D triculture systems, see the Application Protocol: Culturing and Assaying Calcium Transients of 3D Cardiac Tri-Culture Microtissues
Compatible with High-Sensitivity Detection of Calcium Transients in Tri-Culture
Three-dimensional multi-cellular systems containing iCell Cardiomyocytes or iCell Cardiomyocytes2, iCell Endothelial Cells and cardiac fibroblasts demonstrate enhanced amplitude in calcium transient assays. For information on 3D systems, see the Application Protocol: Culturing and Assaying Calcium Transients of 3D Cardiac Tri-Culture Microtissues

Calcium transients were measured using EarlyTox calcium dye. (A) Representative calcium traces for 5,000 and 10,000 total cell 3D Tri-culture cardiac microtissues. (B) Beat rate is not different between 5,000 or 10,000 cell triculture microtissues and control cardiomyocyte only microtissues. (C) Representative calcium traces for 5,000 cell tri-culture and 5,000 cell cardiomyocytes only microtissues (CM only).

Figure 6: Barrier Disruption Effect of Thrombin on iCell Endothelial Cell
Barrier Function Assay Using the xCELLigence RTCA Platform
iCell Endothelial Cells exhibit barrier function activity that can be disrupted by treatment with thrombin and reliably assessed using impedance-based platforms. iCell Endothelial Cells provide an in vitro test system that recapitulates native human endothelium properties and functions while the xCELLigence RTCA Cardio System provides a label-free technology for non-invasive monitoring of cell behavior and viability. The methods and results presented here highlight how to gather relevant data on human endothelial viability and barrier function. Together, iCell Endothelial Cells and impedance-based technologies offer a valuable cell model system for understanding the endothelial barrier characteristics, mechanisms of endothelial barrier dysfunction, and dynamic modulation of the endothelium permeability, enabling a wide range of applications in academic and pharmaceutical research. iCell Endothelial Cells were cultured for 48 hours on the E-Plate in Complete iCell Endothelial Cells Maintenance Medium before the addition of thrombin. (A) The representative Cell Index curves showed the dose-dependent disruption effect of thrombin on the barrier function and the recovery phase. (B) The percentage of Cell Index compared to pre-treatment baseline levels was calculated at the time of thrombin addition, at 9 hours post-treatment, or at 21 hours post-treatment (mean ± SD, n = 2 wells).
