Viability analysis of different passages of rabbit endothelial progenitor cells derived from two biological sources.
| Cell Status /Passage | Cell Type | P0 | P1 | P2 | P3 |
|---|---|---|---|---|---|
| Live | EPCs | 83.8 ± 4.8 | 84.7 ± 1.3 | 91.5 ± 2.9 | 85.1 ± 9.3 |
| BEPCs | 93.0 ± 3.3 | 89.2 ± 6.7 | 92.5 ± 2.8 | 93.2 ± 1.3 | |
| Apoptotic | EPCs | 0.9 ± 0.6 | 1.0 ± 0.8 | 0.6 ± 0.1 | 0.3 ± 0.1 |
| BEPCs | 1.0 ± 0.4 | 1.3 ± 0.9 | 2.1 ± 0.9 | 1.9 ± 0.8 | |
| Dead | EPCs | 15.4 ± 4.6 | 14.2 ± 1.9 | 7.9 ± 3.0 | 14.6 ± 9.4 |
| BEPCs | 6.0 ± 3.1 | 9.5 ± 5.9 | 5.5 ± 2.1 | 4.9 ± 0.9 |
The data are expressed as the mean ± SD; P0—initial culture, P1—first passage, P2—second passage, P3—third passage; Live—unstained cells; Apoptotic—cells positive for Annexin V; Dead—cells positive for propidium iodide.
