Category | Fibrin-only control | 0.1 mg/mL fibronectin | 1.2 mg/mL collagen type I | 1.5 mg/mL hyaluronic acid |
---|---|---|---|---|
Vessel penetration | 1 | 1 | 2 | 3 |
Vessel density at construct interface | 1 | 1 | 3 | 3 |
Overall CAM vessel density | 4 | 4 | 2 | 1 |
Construct remodeling | 1 | 1 | 3 | 4 |
Cellular invasion | - | 1 | 3 | N.D. |
Images from Figure 4 were analyzed and graded from lowest (1) to highest response (4). A dash (-) means that the response never occurred and N.D. means that the response could not be measured. Cellular invasion of fibrin containing 1.2 mg/mL collagen type I was determined by H&E analysis of the sample shown in Figure 4.
