Table 2. Comparison of neuropilin-1 (NRP-1) and neuropilin-2 (NRP-2) expression in alveolar macrophages and interstitial macrophages in lung tissue remote to the cancer nest (physiologically normal lung) (n = 5).
Type of macrophages | Number of NRP-1 positive cellsA) (mean ± SD) | Number of NRP-2 positive cellsA) (mean ± SD) |
---|---|---|
Alveolar macrophages | 9.2 ± 3.8* | 8.9 ± 3.9* |
Interstitial macrophages | 0 ± 0* | 0 ± 0* |
* p< 0.01 significant between alveolar macrophages and interstitial macrophages by the Mann-Whitney U-test.
