Figure 3.

Observations of a late-outgrowth endothelial cell (OEC) colony correlate with low blood pressure. (a) OECs were identified by their cobblestone morphology and proliferative potential and converted in 9 of 20 patients from 7 to 17 days in culture. (b) Investigations between an observed proliferative colony and colony-forming units (CFUs) at 7 days and (c) clinical parameters were investigated for correlations (n = 20). Blood pressure was significantly lower in patients whose cells went on to form OECs (systolic blood pressure, P < 0.0365; diastolic blood pressure, P < 0.0208). Data are mean ± SD and were analyzed using the Student t-test. Bar = a: 500 μm; b: 50 μm. **P < 0.01, *P < 0.05.
