Evaluation of anticancer agents using patient-derived tumor organoids characteristically similar to source tissues. Oncol Rep. 2018 Jun 18;: Authors: Tamura H, Higa A, Hoshi H, Hiyama G, Takahashi N, Ryufuku M, Morisawa G, Yanagisawa Y, Ito E, Imai JI, Dobashi Y, Katahira K, Soeda S, Watanabe T, Fujimori K, Watanabe S, Takagi M Abstract Patient-derived tumor xenograft models represent a promising preclinical cancer model that better replicates disease, compared with traditional cell culture; however, their use is low-throughput and costly. To overcome this limitation, patient-derived tumor organoids (PDOs) were established from human lung, ovarian and uterine tumor tissues, among others, to accurately and efficiently recapitulate the tissue architecture and function. PDOs were able to be cultured for >6 months, and formed cell clusters with similar morphologies to their source tumors. Comparative histological and comprehensive gene expression analyses proved that the characteristics of PDOs were similar to those of their source tumors, even following long-term expansion in culture. At present, 53 PDOs have been established by the Fukushima Translational Research Project, and were designated as Fukushima PDOs (F‑PDOs). In addition, the in vivo tumorigenesis of certain F‑PDOs was confirmed using a xenograft model. The present study represents a detailed analysis of three F‑PDOs (termed REME9, 11 and 16) established from en...
