Figure 4: Functional characterization of iPSC-Heps. The uptake of LDL was measured by incorporation rate of DiI-Ac-LDL and the presence of stored glycogen was determined by PAS staining. Both (a) LDL uptake and (b) glycogen synthesis were evaluated over 4 weeks post-differentiation. Data shown here are the mean ± SD. * versus Week 0.
