Figure 7

hiPSC-derived neural progenitors differentiate into neurons when seeded inside of mechanically stable genipin cross-linked fibrin scaffolds. (A) Neural aggregates seeded in fibrin degraded the fibrin within 5 days and attached to the plate bottom, whereas (B) neural aggregates seeded in 2.5 mM fibrin-genipin scaffolds differentiated within the 3-D scaffold which remained intact for 2 weeks. Each image represents a single neural aggregate with an initial seeding density of 4000 cells/aggregate. Image D is representative of 10 out of 24 biological replicates, which correlates with the percentage of neural aggregates showing signs of differentiation at the time of seeding.
