Figure 4From: In vitro drug release behavior from a novel thermosensitive composite hydrogel based on Pluronic f127 and poly(ethylene glycol)-poly(ε-caprolactone)-poly(ethylene glycol) copolymerHEK 293 cell viability assay. Cell containing 1 × 104 cells in DMEM containing 10% FBS was incubated with S1, S3, S4 and S6 copolymers in 96-well in a humidified atmosphere containing 5% CO2 at 37°C for 48 h. Error bars represent the standard deviation (n = 6).Back to article page
