Immunological Risk Assessment of Xenogeneic Dural Patch by Comparing with Raw Material via GTKO Mice

Figure 1

(a) The TEM graphs of dural patch: (A) bovine pericardium before decellularization; (B) bovine pericardium after decellularization. The image was taken at ×50,000 magnification. Scale bar: 200 nm. (b) The Sirius red staining image of dural patch: (A) bovine pericardium before decellularization; (B) bovine pericardium after decellularization. The image was taken at ×400 magnification. Scale bar: 100 μm. The arrows show green fine fiber, representing type III collagen. (c) SEM micrographs of dural patch. Images (A), (B), (D), and (E) were taken at ×100 magnification, and images (C) and (F) were taken at ×300 magnification.
