| α Enolase and epidermal growth factor receptor showed homogeneous staining throughout the limbal explant at all time points. No immunoreactivity was observed in the limbal epithelial cells for CD34 or for the neuroendocrine, Langerhans cells, or melanocyte markers at any of the time points. | |||||||||
