Figure 7From: Hedgehog pathway responsiveness correlates with the presence of primary cilia on prostate stromal cellsPC-3, 22RV1, LNCaP, and DU145 prostate cancer cell lines do not express cilia. Cells were plated at confluence and grown in low serum media. Nuclei are stained with DAPI (blue) and microtublules are stained with anti-acetylated tubulin (green).Back to article page
