We developed a new method for evaluation of the purity of cell population in primary cultures of hepatocellular carcinoma. Expression of potential surface molecular markers on primary cultures of renal tumors was assayed by the method of flow cytofluorometry. CD24 and CD70 were identified as differential markers, which allowed us to distinguish cancer cells from tumor stromal cells in vitro. A negative marker CD90 was expressed on fibroblasts of the tumor stroma, but not on cancer cells. Combined use of these three markers allows evaluation of the severity of tumor culture contamination with stromal cells.
Objective: to compare the predictive value of RENAL, PADUA, C-index nephrometry score systems according to projection of complexity of operative measure in terms of warm ischaemic time, extent of blood loss and rate of postoperative complications. Materials and methods. Information for the research was collected from 314 patients with localized kidney cancer, who had laparoscopic partial nephrectomy from January 2012 to May 2017. In 210 (66.8 %) cases, in addition to the routine examinations, 3D modelling and
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
