Figure 3: Expression of selected cell markers in LNCaP and PC3 human prostate cancer cells. The figure illustrates the expression of PCR products corresponding to mRNAs encoding three putative stem cell markers (Oct-4, Suz-12 and Cripto-1) and three cell differentiation markers (Cx32, Cx43 and AR) in different cell cultures conditions. The data shown are representative of at least 3 independent experiments. β-actin was used as a housekeeping gene. Plastic (2D cell cultures); 2-4-6d, 2-4-6 days of 3D cell cultures.
