Fig 9. The levels of albumin and tight junction occludin protein were analyzed by western blot at day 20.

Fig 9

Expression of occludin and albumin from all hydrogel samples was observed. Overall, level of albumin from spheroids inside PEG-based hydrogels increased in the order of P12.5% (12.5% PEGDA) < PF10% (10% PEGDA + 1% PF) < PF7% (7% PEGDA + 1% PF) < PF3% (3% PEGDA + 1% PF). Spheroids in PF3% and PF7% produced higher albumin at day 20 compared to PF 10% and P12.5%. The highest level of occludin was expressed in the most compliant gel (PF3%).
