Five Known Endothelial-Specific Genes in the dbEST Pools
| Known endothelial-specific gene | Hits in the nonendothelial pool | Hits in the endothelial pool |
| von Willebrand factor (vWF) | 1 | 27 |
| FLT1 VEGFreceptor | — | — |

The number of expressed sequence tags (ESTs) in the endothelial pool is relatively small (∼11, 117), and not all known endothelial genes are represented.
