Clinical and experimental research suggests that the basal cells of the limbal epithelium are the stem cells of the corneal epithelium [3–5]. The main characteristic of a stem cell is the capacity to divide asymmetrically: a daughter cell remains stem cell while the second undertakes a path of irreversible differentiation. The latter cells are denominated transit amplifying cells and are characterized by a great proliferative capacity capable of providing a high number of epithelial cells necessary for the constant renewal of the corneal epithelium and restoring cell loss in case of trauma [6–9].
