Fig. 3From: The opposing action of stromal cell proenkephalin and stem cell transcription factors in prostate cancer differentiationReversal of reprogramming by PENK. The top row of photomicrographs (magnification 100x) show the cell appearance of LNCaP vs. LNCaP* vs. LNCaP*/PENK. The electropherogram confirms the downregulation of SOX2 in LNCaP*/PENK. The neo signal provides sample loading control. The gel picture is composed of two halves of a single run (bottom and top rows of wells with different background staining intensity). The bottom row of photomicrographs (magnification 200x) show a direct comparison of the colony morphology between neoRbsrR LNCaP*/PENK and neoR LNCaP/PENKBack to article page
