Figure 2. C4-2B cell viability is retained when cultured in the HA hydrogels.

Figure 2

Phase microscope images of cell cluster growth in HA hydrogel over seven days (A). Phase microscope images of cell growth on 2D plastic monolayer over seven days (B). Viable cell numbers in HA hydrogel compared to plastic over seven days (C). Trypan blue positive dead cells were excluded from these counts. Basal level of cell death in HA hydrogel or on plastic over seven days (D). Dead cells were counted after staining with trypan blue. * p<0.05, n = 3, error bars = SEM.
