Overview
Rat Primary Pulmonary Artery Endothelial Cells are rat frozen primary cells from blood vessel used for vascular biology, barrier function, leukocyte trafficking, and tissue-specific microvascular studies. These cells display adherent, polygonal growth characteristics.
Key elements and design rationale
- Biological source: Rat (R. norvegicus)
- Tissue origin: Blood Vessel
- Growth properties: Adherent, polygonal
- Format: Frozen
- Reported expression/markers: vWF, CD31
- Donor history: Normal tissue
- Biosafety level: II
Endothelial cells line the luminal surface of blood vessels and regulate barrier properties, hemostatic balance, immune cell trafficking, angiogenic signaling, and tissue-specific exchange processes.
Research relevance and current trends
- Primary endothelial models are used to study barrier integrity, inflammatory activation, and permeability changes in tissue-specific vascular beds.
- Co-culture systems with immune, stromal, or parenchymal cells are increasingly used to model microenvironment-dependent signaling.
- Researchers often compare donor, vessel-bed, or organ-specific phenotypes to capture biologically relevant heterogeneity.
Common research applications
- Assess barrier function, adhesion molecule regulation, or cytokine-driven endothelial activation in vitro.
- Model angiogenic responses, matrix interactions, and vessel-bed-specific signaling under defined culture conditions.
- Use in co-culture or transwell systems to study leukocyte transmigration and paracrine crosstalk.
Product-specific data supplied for this listing

- Split Ratio: 1:2
Notes for experimental interpretation
- Primary cells can show donor-dependent and passage-dependent variation, so morphology, growth rate, and marker expression should be interpreted in the context of the specific lot and culture history.
- Attachment matrix, medium formulation, and gas conditions can materially influence phenotype maintenance and experimental readouts; use the recommended culture system where possible.
- Cryopreserved recovery conditions matter for viability and downstream behavior. We recommend using serum-free CryoGuard™ Freezing Media (TM078).
- Marker panels should be interpreted together with morphology and functional readouts rather than as a standalone identity measure.
- Thaw cells quickly in a 37°C water bath while agitating gently (maximum 2 minutes). The vial cap should be kept above the water level to minimize the risk of contamination.
- Decontaminate the vial by spraying and wiping the exterior of the vial with 70% ethanol. From this point onwards, all operations should be strictly carried out inside a biological safety cabinet using aseptic conditions.
- Transfer the cell suspension into a 15ml sterile conical tube containing 8-10ml of pre-warmed, complete growth media. Centrifuge cells at 120xg for 5 minutes.
- Aspirate the supernatant without disturbing the cell pellet. Re-suspend the cell pellet in 6ml of the recommended pre-warmed, complete growth media and dispense into a T25 culture flask.
- Incubate the cells at the recommended conditions.
- Change media the following day to remove non-adherent cells and replenish nutrients.
- Change media every 24-48 hours, and check cells daily under microscope to verify appropriate cell morphology. Change media every day when cells are >70% confluent. Pre-wash cells with 1X DPBS, No Ca, No Mg (CH110) 1-2 times whenever replacing media.
- Aspirate the culture media, and wash the adherent layer 1-2 times using 5ml sterile pipette with sterile 1X DPBS, No Ca, No Mg (CH110) to dislodge loosely attached cells and remove fraction. Remove and discard the wash solution from flask.
- Incubate cells with add 2ml of pre-warmed 0.05% Trypsin-EDTA for 3-5 minutes. As soon as cells detach (may require few firm gentle taps) add 8-10ml of complete culture media supplemented with 10% FBS to neutralize the trypsin.
- Plate cells in gelatin precoated flasks and incubate the cells at the recommended conditions.
- Change culture media the following day to remove non-adherent cells and replenish nutrients.
- Change media every 24-48 hours, and check cells daily under microscope to verify appropriate cell morphology. Change media every day when cells are >70% confluent. Pre-wash cells with 1X DPBS, No Ca, No Mg (CH110) 1-2 times whenever replacing media.
