Schematic overview of the prostate tissue sample collection and sectioning. The cylindric sample (3 mm diameter, 2 mm height) was collected from the peripheral zone of a slice of whole-mount human prostate and subsequently cryo-sectioned. The consecutive sectioning order of the three replicates (sets A, B, and C) with randomized section order is shown for each protocol per set (FF = fresh frozen, RTV = room temperature vacuum dried and sealed, FFix = formalin fixed, FFPS = formalin fixed, paraffin sealed).
