Human Endothelial Cells derived from Heart (Cardiac Microvascular) within the Cardiovascular system.\u003c\/p\u003e\n\u003cp\u003eThe endothelial cells modulate vascular tone by release of several endothelium-derived contracting and relaxing factors, by regulation and degradation of vasoactive peptides, and by enzymes located on the Cardiac microvascular endothelial cells (HCMEC) play important roles in myocardial function. HCMEC regulate vascular tone by releasing and degrading endothelium-derived vasoactive factors, and modulating the local levels of vasoconstrictors and vasodilators through their enzymatic activities. Many of these substances can also modify myocardial contractile behavior [1] . Furthermore, microvasculature has been shown to participate in the regulation of leukocyte recruitment, inflammation, and angiogenesis. They are also capable of trans-differentiating into myofibroblasts, suggesting a role in aberrant accumulation of matrix and fibrotic disorders [2] . HCMEC cultures provide an invaluable tool for understanding HCMEC physiological and pathophysiological relevance in cardiac function and disease. iXCells Biotechnologies provides high quality HCMEC, which are isolated from human heart and cryopreserved at P2, with \u0026gt;0.5 million cells in each vial. These HCMEC express vWF\/Factor VIII, CD31 (PECAM) (Figure 1), and Dil-Ac-LDL by uptake. They are negative for HIV-1, HBV, HCV, mycoplasma, bacteria, yeast, and fungi and can further expand for in Endothelial Cell Growth Media under the condition suggested by iXCells Biotechnologies. Figure 1. (A) Immunofluorescence staining for vWF (red) and CD31 (green). (B) Flow analysis showed that 85.09% of the cells are positive for CD31.\u003c\/p\u003e\n\u003ch2\u003eKey elements and design rationale\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCell identity:\u003c\/strong\u003e Endothelial Cells (Primary Cells)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSource context:\u003c\/strong\u003e Heart; Cardiac Microvascular; Cardiovascular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBiosafety level:\u003c\/strong\u003e BSL-2 (follow your institution’s biosafety program and local regulations)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eProduct-specific elements (such as tissue source, donor background, and cell classification) help frame how results should be interpreted across assays and experimental conditions.\u003c\/p\u003e\n\u003ch2\u003eBiological background\u003c\/h2\u003e\n\u003cp\u003eEndothelial cells form the inner lining of blood vessels and regulate barrier function, leukocyte trafficking, coagulation balance, and angiogenic remodeling in response to biomechanical and inflammatory cues.\u003c\/p\u003e\u003cp\u003eAcross primary and specialty cell models, experimental outcomes can be influenced by donor heterogeneity, passage history, confluence, and media composition.
