Product Introduction
| Cell Name | Mouse Aortic Endothelial Cells (Primary cell immortalization) |
| Species | Mouse |
| Tissue | Aortic tissue |
| Growth Properties | Adherent |
| Morphology | Endothelial-like |
| Isolation Method | Mouse aortic endothelial cells (primary cell immortalization) from Procell Laboratory were generated by lentiviral delivery of the SV40T gene into primary mouse aortic endothelial cells, followed by antibiotic selection and serial subculture screening. Each vial contains approximately 5 × 10⁵ cells. |
| Identity Markers | Mouse aortic endothelial cells (primary cell immortalization) isolated from Procell Laboratory exhibit positive immunofluorescence staining for CD31, with a purity greater than 90%. In addition, the cells test negative for HIV-1, HBV, HCV, mycoplasma, bacteria, yeast, and fungi. |
| Background | Mouse aortic endothelial cells (primary cell immortalization) (Mus musculus) from Procell Laboratory are generated from primary mouse aortic endothelial cells by lentiviral transduction of the SV40 large T antigen (SV40T) gene, followed by antibiotic selection and clonal screening. Mouse aortic endothelial cells are isolated from aortic tissue. They constitute a monolayer of endothelial cells lining the luminal surface of the aorta, arranged in a cobblestone-like pattern, forming a selective barrier between blood and the vessel wall within the circulatory system and expressing CD31 (PECAM-1). Their principal functions include: secreting vasoactive substances such as nitric oxide and prostacyclin to maintain vasodilation and homeostasis; regulating vascular permeability via tight junctions and participating in inflammatory cell adhesion; and sensing blood flow shear stress and mediating vascular remodeling. Impairment or disruption of the endothelial barrier and homeostasis is closely associated with the occurrence of cardiovascular diseases such as atherosclerosis. In vitro-cultured mouse aortic endothelial cells provide an important experimental model for studying vascular inflammatory mechanisms, endothelial dysfunction, and cardiovascular drug screening. |
| Instructions | 1. Check all containers for leakage or breakage. 2. Remove the frozen cells from the dry ice packaging and immediately transfer them to liquid nitrogen (liquid or vapor phase) for long-term cryopreservation. |

Q:1 The color of cryopreserved cells varies, with some appearing pink and others yellowish. Does this variation affect their viability after thawing?
AnswerThis phenomenon frequently occurs between different cryopreservation batches, and is associated with cell density, cryopreservation solution composition, and pH changes induced by temperature variations. This discoloration occurs only occasionally, and does not necessarily indicate compromised cell viability. We recommend attempting cell resuscitation first to assess their condition.
-
Q:2 How can I improve the survival rate of cryopreserved cells stored at -80°C?
AnswerWhen storing cryovials, place them in the innermost compartment of the refrigerator's freezer section; avoid placing them on the door shelves or near the refrigerator opening. Additionally, we recommend using refrigerators that are opened less frequently to minimize temperature fluctuations caused by opening and closing the door.
-
Q:3 How long can cells be preserved in a -80°C freezer?
AnswerThe preservation duration of cells at -80°C depends on the operating frequency of the refrigerator and the temperature sensitivity of the cells themselves; therefore, there is no standardized storage period. It is recommended to transfer the cells into liquid nitrogen for long-term storage as early as possible.
-
Q:4 For frozen cells transported via dry ice, should they be stored at -80°C or in liquid nitrogen upon receipt?
AnswerIt is recommended to immediately transfer the received frozen cells into liquid nitrogen for long-term storage; storage at -80℃ should only be used as a short-term interim solution. This is because at -80℃, cellular metabolism is significantly slowed but not completely halted. In addition, frequent opening and closing of the -80℃ freezer causes temperature fluctuations that reduce cell viability.

Q:5 My cells are growing very slowly. What could be the cause of this?
AnswerPlease see some common reasons below, and solutions to the issue: - Growth medium is not correct: Use pre-warmed growth medium as recommended by the supplier. - Serum in the growth medium is of poor quality: Use serum from a different lot. and choose good quality serum to ensure nutrition. - Cells have been passaged too many times: Use healthy, low-passage number cells. - Cells were allowed to grow beyond confluency: Passage mammalian cells when they are in the log-phase before they reach confluency. - Culture is contaminated with mycoplasma: Discard cells, media, and reagents. Obtain new stocks of cells, and use them with fresh media and reagents.

Q:6 What factors can contribute to rapid cell death/culture failure?
AnswerThere are a number of events that can contribute to this: 1. Incorrect CO2 levels:Monitor the level of CO2 manually with a Fyrite kit, available from Bacharach. Check if the manual readings concur with the readings displayed on the incubator. If the incubator has a trace readout, check the printout for fluctuations in CO2 level. Check the settings to ensure that CO2 levels are set at appropriate levels for your cell line (usually between 5 and 10%). Check line connections frequently for leaks. Avoid frequent opening and closing of incubator doors. 2. Temperature fluctuations in the incubator:Monitor the temperature of incubator with a good thermometer inside the incubator. 3. Amphotericin B or other preventive antibiotics/antimycotics are present at toxic concentrations:Use at recommended levels. 4. Humidity is incorrect:Check the water level in the water pan. Humidity is vital to appropriate gas exchange for many types of cells and media. 5. Incorrect osmotic pressure in medium:Check osmolality of complete medium. Most mammalian cells can tolerate an osmolality of 260 to 350 mOsm/kg. Additions of reagents such as HEPES and drugs may affect osmolality. 6. Contamination by microorganisms:Bacterial and fungal contaminations are usually easily visible; symptoms of mycoplasma contamination are more subtle, and careful monitoring of culture morphology and regular testing are necessary to detect this type of contamination. 7. Inappropriate medium is being used:Double-check that the medium used is appropriate for your cell type and culture application. For example, ensure that the medium being used for serum-free culture is actually designed for serum-free culture; make sure that appropriate selective drugs are used at appropriate levels; check the expiration dates for the reagents being used; and store medium at appropriate temperatures in the dark.
