Human Prostate Cancer Cell Line (CWR-R1)

CWR-R1 is a cell line derived from the castration-recurrent human prostate cancer CWR22 xenograft.


  • CWR-R1 cells have a functional androgen receptor with a single mutation (AR-H874Y) that has a broadened ligand specificity and is activated at low concentrations of testosterone or dihydrotestosterone (DHT)
  • Cells express AR full length (AR-FL), AR-V7 and PSA mRNA and protein
  • Cells can be propagated for over 50 passages and growth is increased by low levels of DHT
  • Cell line is a co-culture of epithelial and stromal fibroblasts that grow as a monolayer

Prostate cancer is the development of cancer in the prostate, a gland in the male reproductive system. The androgen receptor (AR) helps prostate cancer cells to survive and is a target for many anti cancer research studies by looking at inhibition.

Source: CWR22 human prostate xenograft
Comments: The CWR-R1 cell line is a co-culture of epithelial and stromal fibroblasts. Do not use cells past passage 50 or fibroblasts will take over the culture. Expand cells and freeze stocks in liquid N2. For 10 ng/ml EGF, add 10 µl to 100 ml PGM media of 100 µg/ml EGF stock. Add 1 ml sterile dH20 to 100 µg vial, store in 50 µl aliquots at -20°C. EGF is stable ~1 week in media at 4°C. Phenol red-free, serum-free medium is the same except use 500 ml Improved MEM Zinc Option (Gibco 10373-017) without adding EGF or serum.
Storage: Liquid nitrogen
Shipped: Dry Ice
