(a), (c), and (e) are the HE and CD34 immunohistochemical staining of the commercial VSDO’s surface neotissue at 1 month after implantation. On the occluder’s surface neotissue, HE staining found no flat cells. CD34 immunohistochemical staining found no positive staining particles and scanning electron microscopy also no endothelial cells. (b), (d), and (f) at 3 months show that endothelial cells presented at the surface of neotissue.
