In Vivo Remodeling of Fibroblast-Derived Vascular Scaffolds Implanted for 6 Months in Rats

Figure 2

Implantation and in vivo imaging of the graft. Picture of the same scaffold immediately after implantation (a) and 6 months later (b), showing integration of the graft. The white arrows point to the anastomotic sites. (c) In vivo ultrasound before sacrifice 6 months after implantation confirming aortic blood flow. The two parallel lines in the central aspect of the aorta are the region in which the velocity is measured (Doppler gate), the long white line perpendicular to the Doppler gate is for a rapid visual identification of the Doppler gate, and the smaller white line is the Doppler angle.
