The capillary density of ischemic ATM sequentially and significantly increased in the DF-521-administered group from day 4 to day 14 post ischemia (848 ± 238/mm2 on day 4, 1,318 ± 321/mm2 on day 7; P = 0.04 vs. day 4, 1,839 ± 483/mm2 on day 14; P = 0.036 vs. day 4 or day 7). This evidence concerns the gene ATM and ischemia.
