Conventional PCR analysis shows the expression pattern of CKs in human ALCs, fetal OEs, fetal SE and ES-ECs. (a) CK25 was only present in SE while absent in ALCs, OEs and ES-ECs. CK4 was present in both ALCs and OEs, while absent in SE and ES-ECs. (b) One representative DNA electrophoresis image shows that CK76 was present in ALCs, ES-ECs and OEs, while absent in SE and hESCs. ALC, ameloblast-lineage cell; BMP4, bone morphogenetic protein 4; CK, cytokeratin; ES-EC, hESC-derived epithelial cell; hESC, human embryonic stem cell; OE, oral epithelial cell; SE, skin epithelium.
