Fig. 2From: The Glypican proteoglycans show intrinsic interactions with Wnt-3a in human prostate cancer cells that are not always associated with cascade activationImmunofluorescence assay to investigate selected GPCs’ localization in RWPE-1, PC-3, DU-145, and LNCaP cells. Cell staining was assessed by confocal microscopy. The different glypicans are stained in red, and nuclei, stained with DAPI, are in blue. The scale bar equals 100 μmBack to article page
