Fig. 6From: Consistent apparent Young’s modulus of human embryonic stem cells and derived cell types stabilized by substrate stiffness regulation promotes lineage specificity maintenanceMaintenance of lineage specificity in HBs during in vitro culture on different substrate stiffness. a AYM measurement of parental HBs with the AFP-mCherry reporter using AFM. b Brightfield and immunostaining images of AFP for HBs cultured for 5 days on substrates with different stiffness. Scale bars = 100 μm. c PROX1 and AFP expression in HBs cultured for 5 days on substrates with different stiffness. d Growth curve of HBs over 3 passages on the 3.5 kPa substrate and coverslip. FACS analysis of PROX1 and AFP e in HBs cultured for 5 days on substrates with different stiffness, and f in 3 passages of HBs on the 3.5 kPa substrate and coverslip. g PROX1 and AFP expression in 3 passages of DE on the 3.5 kPa substrate and coverslip. *P < 0.05, **P < 0.01, ***P < 0.001, ****P < 0.0001Back to article page
