Comparative features of stem cells obtained from four different epithelial tissues. (A) Model of the four epithelia investigated in this study: skin, oral mucosa, cornea and conjunctiva and their organization at tissue level. (B) Colony forming efficiency of H‐SESCs, H‐OMESCs, H‐LESCs and H‐CESCs evaluated at the last passage in culture. H‐SESCs, human skin epithelia stem cells; H‐OMESCs, human oral mucosa epithelial stem cells; H‐LESCs, human limbal epithelia stem cells; H‐CESCs, human conjunctival epithelial stem cells
