Figure 1. Stem cell cultures exhibit p63 and nestin immunoreactivity

Corneal stem cells exhibit immunoreactivity for p63 and the neuroepithelial marker nestin. A: p63 immunoreactive cells are evident as red nuclei. Co-localization of p63 (red) and nestin (brown) immunoreactivity (long arrow), or p63 without nestin (short arrow). B: Nestin immunoreactive cell lacking p63-immunoreactive nucleus. Scale bar represents 5 μm.
