Ultrastructural analysis of H9 hESCs cultured on MEF. (A) Apical differentiations of epithelial type (arrow) were seen in the cells in contact with the medium. The nucleus is euchromatic. TEM, original magnification ×10,000. (B) Inner ducts (arrow) are also present inside the colony. TEM, original magnification ×10,000. (C) The cytoplasm contains ribosomes, and glycogen is associated with lipid droplets. Mitochondria are elongated (arrow). TEM, original magnification ×15,000. (D) The nucleoli are reticulated. TEM, original magnification ×15,000.
