Histological and Transmission Electron Microscopy Results after Embolization with HydroSoft/HydroFrame Coils in Experimental Swine Aneurysm

Figure 1

Immunohistochemical analysis of proliferating cells. (a) Photomicrographs of CD31-positive cells 4 weeks after embolization in normal arterial tissue and in the bare platinum (BP) and hydrogel coil groups. Scale bars = 50, 20 μm (scale bar of a larger image is 20 μm). (b) Number of CD31-positive cells. (c) Photomicrographs of vWF-positive cells 4 weeks after embolization. Scale bars = 50, 20 μm (scale bar of a larger image is 20 μm). (d) Number of vWF-positive cells. (e) Photomicrographs of PCNA-positive cells 4 weeks after embolization. Scale bars = 50, 20 μm (scale bar of a larger image is 20 μm). (f) Number of PCNA-positive cells.
