(ATCC? PCS-100-010?)

Organism Homo sapiens, human

Tissue Umbilical 

Cell Type Endothelial 

Morphology Cobblestone appearance with large dark nuclei; during proliferation, cells are small and evenly sized, display a high mitotic index and show no presence of smooth muscle cells. 

Growth Properties Adherent 

Biosafety Level 1

 [These primary cells are not known to harbor an agent recognized to cause disease in healthy adult humans. Handle as a potentially biohazardous material under at least Biosafety Level 1 containment. Cells derived from primate lymphoid tissue may fall under the regulations of 29 CFR 1910.1030 Bloodborne Pathogens.  

 ATCC recommends that appropriate safety procedures be used when handling all primary cells and cell lines, especially those derived from human or other primate material. Detailed discussions of laboratory safety procedures are provided in Laboratory Safety: Principles and Practice, 2nd ed. (ASM Press, Washington, DC) (Fleming et al., 1995) and Caputo, J.L. 

Biosafety procedures in cell culture. (1988) J. Tissue Culture Methods 11:223. Appropriate safety procedures should always be used with this material. Laboratory safety is discussed in the following publication: Biosafety in Microbiological and Biomedical Laboratories, 5th ed. HHS Publication No. (CDC) 93-8395. U.S. Department of Health and Human Services, Centers for Disease Control and Prevention. Washington DC: U.S. Government Printing Office; 2007. The entire text is available online at 

Human Material Precaution 

 All tissues used for isolation are obtained under informed consent and conform to HIPAA standards to protect the privacy of the donor’s personal health information. It is best to use caution when handling any human cells. We recommend that all human cells be accorded the same level of biosafety consideration as cells known to carry HIV. With infectious virus assays or viral antigen assays, even a negative test result may leave open the possible existence of a latent viral genome. 

Biosafety classification is based on U.S. Public Health Service Guidelines, it is the responsibility of the customer to ensure that their facilities comply with biosafety regulations for their own country.

Images HUVEC cells with phased contrast, ATCC PCS-100-010 

Comments A complete solution to propagate HUVEC in low serum conditions with or without the addition of human recombinant VEGF. Use of the Endothelial Cell Growth Kit-VEGF will support a faster rate of proliferation because of the presence of several purified human recombinant (rh) growth factors (rh VEGF, rh EGF, rh FGF basic and rh IGF-1) combined with heparin and hydrocortisone. Use of the Endothelial Cell Growth Kit-BBE, which contains Bovine Brain Extract (BBE), is recommended if a more "authentic," less defined culture medium is desired.

Complete Growth Medium 

1，Obtain one growth kit from the freezer; make sure that the caps of all components are tight.,

2，Thaw the components of the growth kit just prior to adding them to the basal medium. It is necessary to warm the L-glutamine component in a 37°C water bath and shake to dissolve any precipitates prior to adding to the basal medium. 

3，Obtain one bottle of Vascular Cell Basal Medium (475 mL) from cold storage. 

4，Decontaminate the external surfaces of all growth kit component vials and the basal medium bottle by spraying them with 70% ethanol. 

5，Using aseptic technique, and working in a laminar flow hood or biosafety cabinet, transfer the volume of each growth kit component, as indicated in either Table 1 or 2, to the bottle of basal medium using a separate sterile pipette for each transfer.   

Table 1. If using the Endothelial Cell Growth Kit-BBE (ATCC PCS-100-040), add the indicated volume for each component:

Table 2. If using the Endothelial Cell Growth Kit-VEGF (ATCC PCS-100-041), add the indicated volume for each component:

Antimicrobials and phenol red are not required for proliferation but may be added if desired. The recommended volume of either of the optional components (GA solution or PSA solution) to be added to the complete growth media is summarized in Table 3. 

Table 3. Addition of Antimicrobials/Antimycotics and Phenol Red (Optional) 

6，Tightly cap the bottle of complete growth medium and swirl the contents gently to assure a homogeneous solution. Do not shake forcefully to avoid foaming. Label and date the bottle. 

7，Complete growth media should be stored in the dark at 2°C to 8°C (do not freeze). When stored under these conditions, complete growth media is stable for 30 days. 

Subculturing 1，Passage normal HUVEC cells when culture has reached approximately 80% confluence.  

2，Warm both the Trypsin-EDTA for Primary Cells (ATCC PCS-999-003) and the Trypsin Neutralizing Solution (ATCC PCS-999-004) to room temperature prior to dissociation. Warm complete growth medium to 37°C prior to use with the cells. 

3，F(xiàn)or each flask, carefully aspirate the spent media without disturbing the monolayer. 

4， Rinse the cell layer two times with 3 to 5 mL D-PBS (ATCC 30-2200) to remove residual traces of serum.

5，  Add pre-warmed trypsin-EDTA solution (1 to 2 mL for every 25 cm2) to each flask,

6， Gently rock each flask to ensure complete coverage of the trypsin-EDTA solution over the cells, and then aspirate the excess fluid off of the monolayer. 

7， Observe the cells under the microscope. 

8，When the cells pull away from each other and round up (typically within 3 to 5 minutes), remove the flask from the microscope and gently tap it from several sides to promote detachment of the cells from the flask surface. When the majority of cells appear to have detached, quickly add an equal volume of Trypsin Neutralizing Solution (ATCC PCS-999-004) to each flask. Gently pipette or swirl the culture to ensure all of the trypsin-EDTA solution has been neutralized.,

9，Transfer the dissociated cells to a sterile centrifuge tube and set aside while processing any remaining cells in the flask. 

10，Add 3 to 5 mL D-PBS (ATCC 30-2200) to the flask to collect any additional cells that might have been left behind. 

11，Transfer the cell/D-PBS suspension to the centrifuge tube containing the trypsin-EDTA-dissociated cells. 

12，Repeat steps 10 and 11 as needed until all cells have been collected from the flask.

13，  Centrifuge the cells at 150 x g for 3 to 5 minutes.

14， Aspirate the neutralized dissociation solution from the cell pellet and resuspend the cells in 2 to 8 mL fresh, pre-warmed, complete growth medium. 

15，Count the cells and seed new flasks at a density of 2,500 to 5,000 cells per cm2. 

16， Place newly seeded flasks in a 37°C, 5% CO2, incubator for at least 24 to 48 hours before processing the cells further. Refer to Maintenance for guidelines on feeding.
