Different transcriptional profiles of human embryonic stem cells grown in a feeder-free culture system and on human foreskin fibroblast feeder layers


Figure 1. hESCs (NF4, NF5 and P096) grown on human foreskin fibroblast. (A) hESCs are positive for alkaline phosphatase staining. The scale bar was 200 μm. (B) Karyotype analysis revealed that these hESCs had a normal karyotype.
