Bead displacement during local collagen matrix remodeling with different growth factors
| Treatment | Bead number | Bead displacement (μm)
|
p value |
|---|---|---|---|
| Average ± SD | |||
| Control (no cells) | 14 | 0.26 ± 1.45 | |
| BSA | 13 | −0.10 ± 0.26 | 0.186 |
| LPA | 15 | 3.48 ± 1.76 | <0.001 |
| PDGF | 11 | 4.86 ± 0.85 | <0.001 |
Measurements were made on images in Figure 2, as well as control matrices with no cells. Positive bead displacement reflects centripetal movement of the beads towards the center of the visual field during the 4-hr interval of the experiment. Student's t-Test was used for statistical comparison of each condition compared to no-cell controls.
