Cross sections of chimeric rat corneas.

<p>(A) Cross sections of chimeric rat corneas reveal that there is no concordance between patches of cells labeled in the epithelium and those labeled in the endothelium. (B) Also apparent is the lack of extensive lateral mixing of cells in the epithelial layer. Cells form mostly contiguous patches through the thickness of the epithelium. Epi. is the epithelium, Str. is the stroma, and End. is the endothelium. eGFP lineage is green.
