Background: Prostate cancers often metastasize to bone. It is hypothesized that interactions between osteoblasts and cancer cells lead to establishment of prostate cancer skeletal metastasis.
Methods: As a result of co-culture between undifferentiated and differentiated osteoblasts and PC-3 and DU-145 prostate cancer cells, gene expressional changes were determined with microarray technology, both Affymetrix® and Illumina® protocols. Characterization of osteoblast differentiation was performed using alizarin red staining of calcium, saffron staining of collagen fibers and quantitative real-time PCR of differentiation markers (RUNX2, Osteocalcin and Alkaline phosphatase).
Results: The Affymetrix® protocol demonstrated that co-culturing of PC-3 cells with differentiated osteoblasts resu.. View More»
