Derivation
WPE-int cells were derived from the RWPE-1 cell line (ATCC CRL-11609) after two consecutive cycles of single cell cloning. To establish the RWPE-1 cell line, 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.
Clinical Data
54
Caucasian
male
Antigen Expression
kallikrein 3 ( KLK3); prostate specific antigen (PSA); expressed (upregulated upon exposure to androgen). RefTokar EJ, et al. Stem/progenitor and intermediate cell types and the origin of human prostate cancer. Differentiation 73: 463-473, 2005. PubMed: 16351690
Receptor Expression
androgen receptor, expressed
Tumorigenic NO
Effects
No, RWPE-1 (ATCC CRL-11609), from which the WPE-int cell line was derived, is not tumorigenic in nude mice
Comments

WPE-int cells exhibit features characteristic of an intermediate cell type on the path to luminal cell differentiation. Cells show very low expression of p63 and MMP-2 and high expression of cytokeratin 18 as compared to the WPE-stem cell line (ATCC CRL-2887). They are anchorage-dependent. RefTokar EJ, et al. Stem/progenitor and intermediate cell types and the origin of human prostate cancer. Differentiation 73: 463-473, 2005. PubMed: 16351690  

The WPE-stem cell line (ATCC CRL-2887), which expresses several features characteristic of stem/progenitor cells, was also derived from RWPE-1 cells after single cell cloning.

The parental cell line RWPE-1 was screened for CMV, HBV, HCV, HTLV 1, HTLV 2, HIV 1, HIV 2, JCV, and MoMuLV DNA sequences. Cells were also tested for 25 species of mycoplasma and Acholeplasma laidlawii. Cells tested negative for all of the above. (personal communication from depositor).
Complete Growth 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.
    • Subculturing
    Volumes used in this protocol are for 75 cm2 flasks; proportionally reduce or increase amount of dissociation medium 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 3.0 to 4.0 mL of 0.05% Trypsin - 0.53mM EDTA solution, diluted 1:1 with D-PBS, and place flask in a 37°C incubator for 5 to 8 minutes. Observe cells under an inverted microscope until cell layer is dispersed (usually within 5 to 8 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 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 6 X 103 to 8 X 103 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.
    Note: 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. Subculture cells before they reach confluence. Do not allow cells to become confluent.

    Subcultivation Ratio: A subcultivation ratio of 1:3 to 1:5 is recommended
    Medium Renewal: Every 48 hours
    Cryopreservation
    Freeze medium: Complete growth medium described above supplemented with 15% fetal bovine serum and 10% (v/v) DMSO.Cell culture tested DMSO is available as ATCC? Catalog No. 4-X.
