Figure 5From: Cell attachment on poly(3-hydroxybutyrate)-poly(ethylene glycol) copolymer produced by Azotobacter chroococcum 7BAdhesion and cell proliferation on biopolymer films. Adhesion and cell proliferation on tested biopolymer films evaluated by XTT test: PHB, PHB-HV, PHB-PEG, and PLA. Data were shown as Mean ± SD; n = 12 (PHB, PHB-HV), n = 8 (PHB-PEG, PLA); * vs PLA, # vs PHB, $ PHB-PEG vs PHB-HV, p < 0.05.Back to article page
