Different transcriptional profiles of human embryonic stem cells grown in a feeder-free culture system and on human foreskin fibroblast feeder layers
Figure 3. Teratomas containing derivatives of all the 3 germ layers. Histological evidence of germ layer differentiation in NF4, NF5 and P096 in the feeder-free culture system or on HFF feeder layers. A typical teratoma containing endoderm (respiratory epithelium), mesoderm (cartilage tissue) and ectoderm (neuroepithelium). Magnification was 400× in total.
