The microscopic appearance of an ependymoma reveals a rosette pattern with the cells arranged about a central vascular space.

For aneurysm and aortic dissection, axial image was most accurate, but SSD, MIP, MPR were better in showing the space relationship of targic vascular lesions with its main branches.

Objective: to construct cloning and prokaryotic expression vector of vascular basement membrane-derived multifunctional peptide and to analyze its space conformation.
