Figure 4: Suspension culture of iHeps on dextran microcarrier beads. (A) The iPSC-hepatocytes culture in a spinner flask is shown in the context of a cell culture incubator. (B) Bright field and fluorescent images show hepatocytes attached onto dextran microcarrier spheres (scale bar 50 μm). For nuclear staining, cells containing beads were incubated with Hoechst dye for 10 minutes.
