In vivo rat cornea: effects of OGF and NTX. Labeling index of basal corneal epithelium in the central cornea, peripheral cornea, limbus, and conjunctiva. Left series of histograms: OGF decreases labeling index of homeostatic rat corneal epithelium. Right series of histograms: NTX increases labeling index of homeostatic rat corneal epithelium. Note: neither OGF nor NTX has any effect on the central corneal epithelium (right and left, top graphs), which is postmitotic. or (derived from [8]).
