Figure 3.

Cross sectional images of the heart 2 and 4 weeks after AMI (Red fluorescence represents PECAM for blood vessels, and green fluorescence represents LYVE 1 for lymphatic vessels). (A) Lymphatic vessels were seldom found in the sham operation group. (B) Newly formed lymphatic vessels were developed in the peri-infarction area in the PBS group. However, the EPC treatment group shows a lesser degree of lymphatics at 2 (C) and 4 weeks (D) after AMI. Relative density of lymphatic vessels was significantly lower in the EPC treatment group (E). Bars, 100 µm, ^*P < 0.05.
