Cell Compositions in Neointima or Atheroma

Mouse group	MAC-1+ cells	α-actin+ cells	CD4+ cells
4 weeks
apoE+/+	47 ± 23%	11 ± 7%	0–5
apoE−/−	58 ± 31%	14 ± 10%	30–50
8 weeks
apoE+/+	23 ± 15%	60 ± 19%	0–3
apoE−/−	63 ± 21%*	33 ± 17%*	10–30

The positive stained cells and total number of nuclei were counted. In each section, two fields (10 × 40) were evaluated. Data from CD4⁺ cells represent ranges of the number of positive cells, since total numbers per field were less than 5 in neointima of apoE+/+ mice. The values are ranges of means ± SD from 2 to 4 sections/animal, n = 4.

* Significant difference between apoE−/− and +/+ mice, P < 0.05.
