Bladder cancer is the ninth most common malignancy in the world. Transitional cell carcinoma (TCC), also referred to as urothelial carcinoma (UC) is the most common form of bladder cancer, occurring in 90% of cases. In this study, we explore urine-derived, 3-dimensional, canine TCC organoids as a possible model to study bladder TCC ex vivo. After establishing the cell lines, we subjected the 3D cells to RNA in situ hybridization (RNA-ISH) and cell viability assays. Overall, 3D cell culture from urine samples of TCC diagnosed canines expressed RNA biomarkers in a similar manner to parent tumors via RNA-ISH and showed more sensitivity to cisplatin treatment when compared to 2D human TCC cells. With further experimentation, canine TCC organoids could become an ideal model to study TCC ex vivo.

"Similar papers" are the closest papers from that journal in the model's embedding space. They show what the match is built on, but the ranking comes mostly from a classifier over the whole training set, not from these examples alone.
