Matrigel improved cell survival compared with the absorbable collagen sponge and POC/TCP. Cells were cultured in (A) absorbable sponge, (B) POC/TCP, or (C) Matrigel. (A,B) Cell survival was poor when cultured for 3 days. (C) Cell survival was high after 2 weeks. Scale bars = 400 µm. (D) Quantification of cell survival in the different materials. Cell survival in Matrigel was significantly higher than that in the other two materials (data are the mean ± SEM; *p < 0.05). (E) Laser confocal microscopy images showing that primary NSCs could differentiate into neurons in Matrigel (×400).
