| Catalogue Number: 05092802 22Rv1 is a human prostate carcinoma epithelial cell line derived from a xenograft that was serially propagated in mice after castration-induced regression and relapse of the parental, androgen-dependent C WR22 xenograft. The cell line expresses prostate specific antigen (PSA). Growth is weakly stimulated by dihydroxytestosterone and lysates are immunoreactive with androgen receptor antibody by Western blot analysis. Growth is stimulated by epidermal growth factor (EGF) but is not inhibited by transforming growth factor beta-1 (TGF beta-1). This cell line is tumorigenic in nude mice. This cell line was deposited by James W Jacobberger, Case Western Reserve University, Cleveland, Ohio, USA. |
