Preliminary in vivo evaluation studies of MTNs. (a) Fluorescent emission detected before EPC injection, 1 h after injection (90 min), on the seventh day, and on the 21st day. Fluorescent images of vessel on the upper right are organized sequentially based on time points. (b) Effects of MTNs on suppressing the intimal hyperplasia based on elastin staining images and intimal hyperplasia index. (c) Re-endothelialization of injured arteries untreated and treated with MTNs after 7 and 21 days. * represents p < 0.05. N = 10.
