Fig. 1From: Porcine pulmonary valve decellularization with NaOH-based vs detergent process: preliminary in vitro and in vivo assessmentsValve characterization: methods. a: macrophotograph of a DPV. b: microphotograph of NPV after trichrome staining illustrating histological assessment of the valves in 3 zones:1: the muscle/2: the leaflet/3: the wall. Scal barr: 1 mm. For histological evaluation, the explanted valves were sectioned in six segments (c) to analyze the three zones (d)Back to article page
