RAOEC from Cell Applications, Inc. provide a useful model system to study many aspects of cardiovascular function and disease. Co-culture of the artery endothelial cells with species-matched smooth muscle cells provides an ideal model for studying the interaction between these two cell types.
RAOEC from Cell Applications, Inc. have been utilized in a number of research publications to:
Investigate critical signaling pathways and mechanisms relevant to proper endothelial function, such as angiogenesis, proliferation, permeability, and search for beneficial modulators for therapeutic use (Sorensen, 2008; Liu, 2009; Makino, 2009; Masuda, 2012; Gros, 2013; Nguen, 2013)
Elucidate molecular mechanisms of various cardiovascular risk factors, including those associated with diabetes, polycystic kidney disease, treatment for allograft rejection and vascular ER stress (Makino, 2008; Chiasson, 2011, Ren, 2011; Padilla, 2013)
Provide a gold standard control for endothelial markers vWF and PECAM/CD31 expression (Hanley, 2008; Imamura, 2010)
Develop drug delivery system for thrombolytic treatment (Mei, 2010)and methods for cardiac regeneration (Lionetti, 2010); design better vascular implants (Ibrahim, 2008; Yao, 2008; Duffy, 2011) and bone tissue engineering (Hamid, 2014)
Additionally, RAOEC from Cell Applications, Inc. were used to investigate the reasons for differential effects of Intermedin (IMD) on permeability of endothelial cells from different vascular beds (Aslam, 2011). Specifically, it was shown that IMD increased permeability of rat coronary microvascular endothelial cells by inducing loss of VE-cadherin from cel-cell junctions, but it reduced permeability of RAOEC and HUVECs because in those cell types IMD instead caused accumulation of VE-cadherin in cell-cell junctions. These differential effects of IMD on VE-cadherin are explained by the fact that, although IMD activates cAMP/PKA and inhibits RhoA/ROCK pathways leading to rearrangement of actin in both cell types, it only causes downstream Rac1 inhibition in rat coronary microvascular endothelial cells, but not in RAOEC or HUVEC. These results highlight the fundamental differences between endothelial cells from different vascular beds and/or microvascular vs. macrovascular endothelia.
