A. Schematic of LNCaP cells chemotactic assay In vitro. A. LNCaP cells migration through 8 μm pore size transwell inserts toward differentiated 3 T3-L1 cells in the bottom wells. B. Migrated LNCaP cells under a light microscope at the undersurface of the inserts were stained with crystal violet (scale bar: 20 μm). C. Cell number assessment of LNCaP cells co-cultured with differentiated 3 T3-L1 cells. **p < 0.01 versus undifferentiated 3 T3-L1 cells; ##p < 0.01 versus differentiated 3 T3-L1 cells
