Total and surface receptor number
| Cell population . | Total VEGFR-2 (105 molecules/cell) . | Surface VEGFR-2 (105 molecules/cell) . |
|---|---|---|
| Long-confluent | 6.4 | 3.9 |
| Sparse | 3.5 | 2.0 |

The number of total VEGFR-2 molecules was calculated as shown in supplemental Figure 2. The number of surface VEGFR-2 molecules was obtained considering the percentage of surface VEGFR-2 (reported in Figure 2B).
