Documentation

ATCC determines the biosafety level of a material based on our risk assessment as guided by the current edition of Biosafety in Microbiological and Biomedical Laboratories (BMBL), U.S. Department of Health and Human Services. It is your responsibility to understand the hazards associated with the material per your organization’s policies and procedures as well as any other applicable regulations as enforced by your local or national agencies.

Cells contain Human papillomavirus (HPV) sequences

ATCC highly recommends that appropriate personal protective equipment is always used when handling vials. For cultures that require storage in liquid nitrogen, it is important to note that some vials may leak when submersed in liquid nitrogen and will slowly fill with liquid nitrogen. Upon thawing, the conversion of the liquid nitrogen back to its gas phase may result in the vial exploding or blowing off its cap with dangerous force creating flying debris. Unless necessary, ATCC recommends that these cultures be stored in the vapor phase of liquid nitrogen rather than submersed in liquid nitrogen.

Detailed product information

Characteristics

Growth properties
Adherent
Derivation
RWPE-2 cells were derived from RWPE-1 cells (ATCC CRL-11609) by transformation with Ki-ras using the Kirsten murine sarcoma virus (Ki-MuSV). Epithelial cells from the peripheral zone of a histologically normal adult human prostate were transfected with a plasmid carrying one copy of the human papilloma virus 18 (HPV-18) genome to establish the RWPE-1 cell line (ATCC CRL-11609).
Ethnicity
White
Gender
Male
Karyotype
At passage 14, a majority of the cells were in the near diploid range (48-54), with the main population being 51, XY.
Tumorigenic
Yes;
Yes, in nude mice
Yes, in soft agar
Antigen expression
Kallikrein 3, KLK3 (prostate-specific antigen, PSA); Homo sapiens, expressed (upon exposure to androgen)
Genes expressed
cytokeratin 8; cytokeratin 18
Expression markers
Androgen receptor, expressed
Comments
RWPE-2 cells form small colonies in soft agar and form tumors when injected into nude mice. Further, a family of tumorigenic cell lines, that mimics multiple steps in prostate cancer progression, was also derived from RWPE-1 cells by exposure to N-methyl-N-nitrsourea (MNU). See the WPE1-NA22 (ATCC CRL-2849), WPE1-NB14 (ATCC CRL-2850), WPE1-NB11 (ATCC CRL-2851) and WPE1-NB26 (ATCC CRL-2852) cell lines.
The depositor reports that the RWPE-1 cell line (ATCC CRL-11609) was screened, and found negative for, Hepatitis B virus, Hepatitis C virus and Human immunodeficiency virus.

Handling information

Unpacking and storage instructions
  1. Check all containers for leakage or breakage.
  2. Remove the frozen cells from the dry ice packaging and immediately place the cells at a temperature below ­-130°C, preferably in liquid nitrogen vapor, until ready for use.
Complete medium
The base medium for this cell line is provided by Invitrogen (GIBCO) as part of a kit: Keratinocyte Serum Free Medium (K-SFM), Kit Catalog Number 17005-042. This kit is supplied with each of the two additives required to grow this cell line (bovine pituitary extract (BPE) and human recombinant epidermal growth factor (EGF). To make the complete growth medium, you will need to add the following components to the base medium:
  • 0.05 mg/ml BPE - provided with the K-SFM kit
  • 5 ng/ml EGF - provided with the K-SFM kit. NOTE: Do not filter complete medium.
  • Temperature
    37°C
    Atmosphere
    95% Air, 5% CO2
    Handling procedure

    To insure the highest level of viability, thaw the vial and initiate the culture as soon as possible upon receipt. If upon arrival, continued storage of the frozen culture is necessary, it should be stored in liquid nitrogen vapor phase and not at -70°C.  Storage at -70°C will result in loss of viability.

    1. Thaw the vial by gentle agitation in a 37°C water bath. To reduce the possibility of contamination, keep the O-ring and cap out of the water.  Thawing should be rapid (approximately 2 minutes).
    2. Remove the vial from the water bath as soon as the contents are thawed, and decontaminate by dipping in or spraying with 70% ethanol. All of the operations from this point on should be carried out under strict aseptic conditions.
    3. It is recommended that the cryoprotective agent be removed immediately.  Centrifuge the cell suspension at approximately 125 x g for 5 to 7 minutes.  Discard the supernatant and resuspend the cell pellet in an appropriate amount of fresh growth medium.
    4. Transfer the vial contents to an appropriate size vessel.  It is important to avoid excessive alkalinity of the medium during recovery of the cells.  It is suggested that, prior to the addition of the vial contents, the culture vessel containing the growth medium be placed into the incubator for at least 15 minutes to allow the medium to reach its normal pH (7.0 to 7.6).
    5. Incubate the culture at 37°C in a suitable incubator.  A 5% CO2 in air atmosphere is recommended if using the medium described on this product sheet.

             

    Subculturing procedure
    Volumes are given for a 75 cm2 flask. Increase or decrease the amount of dissociation medium needed proportionally for culture vessels of other sizes.
    1. Remove and discard culture medium.
    2. Briefly rinse the cell layer with Ca++/Mg++ free Dulbecco's phosphate-buffered saline (D-PBS).
    3. Add 2.0 to 3.0 mL (to a T-25 flask) or 3.0 to 4.0 mL (to a T-75 flask) of 0.05% Trypsin - 0.53mM EDTA solution, diluted 1:1 with D-PBS, and place flask in a 37C incubator for 5 to 8 minutes. Observe cells under an inverted microscope until cell layer is dispersed (usually within 5 to 10 minutes).
      Note: To avoid clumping do not agitate the cells by hitting or shaking the flask while waiting for the cells to detach.
    4. Add 6.0 to 8.0 mL of 0.1% Soybean Trypsin Inhibitor (ATCC® 30-2104™) or 2% fetal bovine serum in D-PBS, as appropriate, and aspirate cells by gently pipetting.
    5. Transfer cell suspension to centrifuge tube and spin at approximately 125 x g for 5 to 7 minutes.
    6. Discard supernatant and resuspend cells in fresh serum-free growth medium. Add appropriate aliquots of cell suspension to new culture vessels. An inoculum of 2 x 104 to 4 X 104 viable cells/cm2 is recommended.
    7. Incubate cultures at 37°C. We recommend that you maintain cultures at a cell concentration between 4 x 104 and 8 X 104 cells/cm2.
    Cells grown under serum-free or reduced serum conditions may not attach strongly during the 24 hours after subculture and should be disturbed as little as possible during that period.
    Subcultivation Ratio: A subcultivation ratio of 1:3 to 1:5 is recommended
    Medium Renewal: Every 2 days
    Reagents for cryopreservation
    Complete growth medium supplemented with 7.5% (v/v) DMSO (ATCC 4-X)
