Immunostaining for PDGFRβ (red), Vimentin (red) and Keratin (green) in a pair of human ccRCC tissues. Cell nucleus was stained blue by DAPI. a. Human ccRCC adjacent tissue (scale bars = 50 μm). b. Human ccRCC tissue (scale bars = 50 μm). c. Human ccRCC tissue (scale bars = 25 μm). Arrows indicate PDGFRβ positive cells surrounding the tumor islands (*) in the ccRCC tissue. # indicates glomerulus and + indicates blood vessel
