Figure 3From: In vivo bioluminescence imaging for viable human neural stem cells incorporated within in situ gelatin hydrogelsIn vitro luciferase activity versus time in F3-effluc cells incorporated within the soft and stiff hydrogels. The same number of F3-effluc cells within GPT 1.8 K and GPT 5.8 K was seeded into the six-well plates. The two hydrogel groups and the cell-only group were compared, and in all three groups, cell density increased continuously up to day 8. *P value <0.1.Back to article page
