FIG. 2.

MSI data allow visualization of implanted vessels perfused with blood from host vasculature following anastomosis. Perfused implanted vessels increased in number and are remodeled over the 21-day observation period. Color images of an acellular control implant (A–D) and a prevascularized implant (E–H) over a period of 21 days. (I–L) Hemoglobin absorption maps corresponding to (E–H). (M–P) Magnified view of the region of interest highlighted in (E) over the same time period. White arrows indicate extravasated blood. Color images available online at www.liebertonline.com/tec
