This study was undertaken to establish an androgen‐sensitive model of human prostatic carcinoma in nude mice. The androgen‐sensitive prostatic carcinoma cell line, LNCaP, was suspended in reconstituted basement membrane (Matrigel) and injected subcutaneously into nude mice. The LNCaP cell line was chosen for the study, because the cell line is androgen‐sensitive and secretes prostate specific antigen (PSA) into culture media. Following injection of 1 × 106 LNCaP cells with 0.25 ml of Matrigel, 88. of mice exhibited palpable tumor burdens after 12 weeks of observation. In addition, significant levels of PSA were observed in the serum of LNCaP‐bearing mice. Bilateral orchiectomy of mice resulted in tumor regression and stabilization of serum PSA levels, compared to testis‐intact controls. A significant correlation of PSA to tumor volume and weight was observed. The castrate level of testosterone was confirmed by radioimmunoassay and was similar to testosterone levels in female nude mice. Matrigel allows for a conducive environment to propagate LNCaP cells in nude mice. Furthermore, the growth can be manipulated by castration, leading to involution of tumor and stabilization of serum PSA level. This in vivo model of hormone‐sensitive human prostate cancer cell line will serve as a model for the study of prostate tumor biology and treatment. © 1993 Wiley‐Liss, Inc.
