Injectable Hydrogel versus Plastically Compressed Collagen Scaffold for Central Nervous System Applications

Figure 2

On (a), the results of the collagen-genipin hydrogel results are depicted showing a gradual decline in the % weight remaining of the hydrogel over the time due to the exposure to the 0.1% collagenase solution. On (b), the results of the same assay for a collagen hydrogel are depicted, indicating a much more rapid decline in the % weight remaining. It is noted that all gels were left in the incubator to “mature” at 37°C for 24 hours before the initiation of the assay.
