Outline of Final Research Achievements

Prostate cancer (PCa) cells frequently invade the surrounding stroma, leading to heterogenous formation of structural atypia. The surrounding stroma contains multiple functionally diverse populations of fibroblasts that trigger numerous changes in PCa cells including motility. Co-cultures of LNCaP cells with seven of the patient-derived fibroblast lines (PrSC, pcPrF-M5, pcPrF-M7, pcPrF-M23, pcPrF-M24, pcPrF-M28, and pcPrF-M31) formed a thick fibroblast layer that resembled human prostate stromal structures. Four patient-derived fibroblast lines (PrSC, M5, M28, and M31) induced an invasive phenotype in LNCaP cells with a cord-like infiltrating growth pattern. Two patient-derived fibroblast lines (M5 and M28) increased CDH2 mRNA expression in LNCaP cells. These results suggest that the existence of multiple functionally diverse populations of fibroblasts in PCa tissue may be responsible for the diversity in PCa cell invasion, leading to heterogenous formation of structural atypia.

Academic Significance and Societal Importance of the Research Achievements

ホルモン療法下でも前立腺癌細胞を悪性化する線維芽細胞の特徴が同定されれば、病理医によるグリソンスコア分類に加えて、癌間質に含まれる線維芽細胞の特徴が「付加情報」として泌尿器科医へ伝わることにより無駄なホルモン療法を1つでも減らす、すなわち効果が見込める患者にだけホルモン療法を施行する個別化ホルモン療法が実現可能となる。本研究で我々が開発した、培養基質を用いて前立腺癌細胞の三次元的な細胞形態の差異を観察する手法は、activeな線維芽細胞を判別するための新規スクリーニング法の開発へと発展できることが期待された。
