Human Spleen Endothelial Cells (HSEC)

Overview

Human Spleen Endothelial Cells (HSEC) is a cell model used for research applications where physiologically relevant identity and donor background support interpretation of experimental readouts. Human Endothelial Cells derived from Spleen (Spleen) within the Blood system.

The spleen performs essential functions in the turnover of erythrocytes. It removes erythrocytes, metabolizes hemoglobin, and recycles iron. The spleen also mounts a primary immune response to antigens in the blood and synthesizes antibodies in its white pulp. Human spleen endothelial cells (HSEC), similar to other endothelial cells, constitute the natural interface between the blood and the underlying tissue. Previous studies have demonstrated an intriguing link between splenic endothelial cells, splenic hamartoma and capillary hemangioma [1]. Splenic endothelial cells ( HSEC ) have also shown a supportive micro-environment for the development of dendritic cells [2]. Furthermore, rapid destruction of young erythrocytes can occur in the spleen due to altered endothelial cell-macrophage interactions [3]. These observations suggest that splenic endothelial cells may play a more compelling role in the mononuclear phagocyte system. iXCells Biotechnologies provides high quality HSEC, which are isolated from normal human spleen and cryopreserved at P1, with >0.5 million cells in each vial. HSEC express vWF/Factor VIII, CD31 (PECAM), and Dil-Ac-LDL by uptake. They are negative for HIV-1, HBV, HCV, mycoplasma, bacteria, yeast, and fungi and can further expand for 12 population doublings in Endothelial Cell Growth Medium under the condition suggested by iXCells Biotechnologies.

Key elements and design rationale

• Cell identity: Endothelial Cells (Primary Cells)
• Source context: Spleen; Spleen; Blood
• Biosafety level: BSL-2 (follow your institution’s biosafety program and local regulations)

Product-specific elements (such as tissue source, donor background, and cell classification) help frame how results should be interpreted across assays and experimental conditions.

Biological background

Endothelial 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.

Across primary and specialty cell models, experimental outcomes can be influenced by donor heterogeneity, passage history, confluence, and media composition. For interpretation, it is common to validate key markers or functional phenotypes in the user’s assay context and to document culture variables consistently.

Research relevance and current trends

• Increasing use of primary and specialty cells to improve translational relevance for target biology and phenotypic screening.
• Adoption of 3D culture formats and co-culture systems to better capture tissue microenvironments and cell–cell interactions.
• Integration of functional readouts with single-cell and multi-omics profiling to connect phenotype with molecular state.
• Expansion of high-dimensional immune phenotyping and perturbation screens to map activation states and functional programs.

Common research applications

• Profile identity markers by flow cytometry or immunostaining in cultured cells
• Measure barrier function and inflammatory activation in endothelial monolayers
• Quantify functional responses to defined stimuli relevant to the model system
• Compare baseline phenotype across donors/conditions using gene expression profiling
• Assess adhesion molecule expression and leukocyte interaction under inflammatory cues

Interpretation typically focuses on how a perturbation (e.g., cytokine exposure, metabolic stress, genetic manipulation, or compound treatment) shifts marker profiles or functional readouts relative to an appropriate control matched for donor and culture variables.

Notes for experimental interpretation

• Donor-to-donor heterogeneity can influence baseline phenotype and treatment response; include biological replicates when feasible.
• Passage number, confluence, and media composition can shift gene expression and functional readouts; track and report these variables consistently.
• Contamination control (including routine mycoplasma monitoring) supports reproducibility in downstream assays.
• Use appropriate negative/positive controls for the readout (e.g., unstimulated controls, pathway agonists/antagonists) to contextualize observed changes.
