Abstract

We analyzed the ability of the bone marrow (BM) stromal cells to achieve confluence and their proliferative capacity in BM primary cultures from 30 untreated lung cancer patients (LCP), 27 breast cancer patients (BCP), and 30 normal controls (NC) when these confluent cells were induced to proliferate following four continuous subcultures. Moreover, we evaluated the production of interleukin-1 beta (IL-1beta), transforming growth factor beta 1 (TGF-beta1), fibronectin, and prostaglandin E2 (PGE2) by pure fibroblasts (fourth passage). A fibroblast colony-forming units (CFU-F) assay was used to investigate the proliferative and confluence capacity. Levels of IL-1beta, TGF-beta1, and fibronectin in conditioned mediums (CM) of fibroblast cultures were measured by enzyme-linked immunosorbent assay (ELISA) kit and PGE(2) by radioimmunoassay (RIA) kit. Confluence was achieved in the 60% of LCP and 78% of BCP primary cultures compared with 100% of NC, and only fibroblasts from seven LCP and six BCP cultures had the capacity to proliferate following four subcultures. Levels of IL-1beta were below 10 pg/ml in both patient groups, while NC had a mean value of 5882.57+/-221.61 pg/ml. Levels of TGF-beta1 in BCP were lower than NC values ( P<...Continue Reading
