Induction of neovasculature formation in ischemic hearts by VEGF-expressing vector. (a) A diagram of a cross section of the left ventricle. The areas used for analyses of vessel density are marked. (b) Blood vessel densities in different areas. MLC, MLCVEGF-injected group; CMV, CMVVEGF-injected group; LacZ, CMVLacZ-injected group; Hepes, Hepes-injected group; Uninj, uninjected group.^*, the differences between the MLCVEGF group and control groups (CMVLacZ, Hepes, and uninjected groups) are significant.^**, the differences between the CMVVEGF group and control groups are significant.
