Figure 4.
Quantitative analysis of CD31 expression in the rat model. By dot blot (A) and ELISA analysis (C), CD31 immunoreactivity in the peri-infarcted area was slightly increased from day 3 to day 14 in both age groups. However, CD31 levels in the young animals were clearly higher than those in aged animals both at day 3 (fourfold; p = 0.001) and day 14 (threefold; p = 0.001) both by dot blot (B) and ELISA(C).
