Human Cardiac Microvascular Endothelial Cells (HCMEC)
Primary Human Cardiac Microvascular Endothelial Cells isolated from heart ventricles from a single donor.
Primary Human Cardiac Microvascular Endothelial Cells (HCMEC) are isolated from heart ventricles from a single donor. The cells are routinely analyzed by immunofluorescent staining: they stain positive for CD31 and Willebrand factor and negative for smooth muscle alpha-actin.
HCMEC intensively interact with cardiomyocytes and therefore have a characteristic phenotype different from other microvascular endothelial cells. HCMEC play an important role in the physiological regulation of coronary blood flow and capillary exchange. Medical conditions such as hypertrophy, ischemia, hypertension, and diabetes mellitus are associated with endothelial dysfunction.
NEW: Our HCMEC are now also available from HLA-typed donors.

- Cell pellet: 1 million cells dissolved in 200µl RNAlater© for subsequent RNA, DNA or protein analysis. Cell pellets cannot be revived.
|Recommended plating density||10,000 – 20,000 cells per cm2|
|Passage After Thawing||P2|
|Tested Markers||von Willebrand Factor (vWF) positive, CD31 positive, Dil-Ac-LDL uptake positive|
|Guaranteed Population Doubling||> 10|

Do the PromoCell HCMEC represent the endocardial cells, i.e. those lining the ventricles? If so, why are they referred to as microvascular endothelial cells?
Our HCMEC (Human Cardiac Microvascular Endothelial Cells) are not endocardial cells. They are isolated from the capillaries in the heart muscle. Therefore, they are in fact microvascular.

Which medium does PromoCell recommend for endothelial cell transfection ?
There are several factors that can influence successful transfections, e.g. viability and density of the cells, choice of the transfection reagent, quality and type of the transfected molecules (plasmids, siRNA, oligonucleotides), as well as the culture medium and supplements used.
When using PromoCell Endothelial Cell Growth Media for cell transfection, please follow the instructions below:
Heparin, which is included in our Endothelial Cell Growth Medium (C-22010/C-22110), Medium 2 (C-22011/C-22111) and Medium MV (C-22020/C-22120) may reduce the transfection efficiency. We therefore recommend to use our heparin-free Endothelial Cell Growth Medium MV2 (C-22022/C-22121). Alternatively, you may use Endothelial Cell Growth Medium Kit (C-22110), Medium 2 Kit (C-22111), or Medium MV Kit (C-22120) without adding the heparin supplement to the Basal Medium.
Please note: Before and after transfection, the cells should be cultured in complete Growth Medium including heparin to ensure optimal growth.
