The Effect of Human and Mouse Fibroblast Feeder Cells on Cardiac Differentiation of Human Pluripotent Stem Cells

Figure 1

Undifferentiated H7 hESC colonies (on passage 15) 3 days after passaging on hFF feeder cells (a) and after 55 passages on MEF feeder cells (b). H7 cells passaged 11 times on hFF feeder cells expressed Nanog (c and d), Oct4 (e and f), SSEA4 (g and h), and TRA-1-60 (i and j). H7 cells on passage 45 on MEF feeder cells expressed Nanog (k and l), Oct4 (m and n), and SSEA4 (o and p). Scale bars 200 μm.
