Quantification of 25F9 Macrophage Staining in Human Coronary Artery Sections

Sample number*	Intimal region type		Macrophage phenotype (% of total immunolabeled cells)
			25F9− CD14+	25F9+ CD14−	25F9+ CD14+
1	Normal		100	0	0
2	Normal†		95	4	1
3	Normal		87	3	10
		Mean ± SEM	94 ± 4	2 ± 1	4 ± 3
4	Lesion‡
5	Lesion		62	11	27
6	Lesion		61	18	21
		Mean ± SEM§	62 ± 1	15 ± 4	24 ± 3

^*Same samples as in Table 4. 

^†Normal intimal region in vessel wall opposite sample 5 lesion. 

^‡Sample lost because of laboratory accident. 

^§All means comparing macrophage phenotypes for normal and lesions were significant, P < 0.05.
