Figure 1. Biochemical validation of the human ES/EB progenitor cell differentiation system.

Figure 1

Lysates made from human ES cells and EBs harvested at different times of differentiation over a 12-day period were immunoblotted with antibodies against specific differentiation markers (Oct4, Nanog, NCAD and CD31). Equal protein amounts were electrophoresed in each gel lane and β-actin was immunoblotted as a loading control.
