Protection of Corneal Limbus from Riboflavin Prevents Epithelial Stem Cell Loss after Collagen Cross-Linking

<div>Analysis of limbal epithelial stem cells. (a) Representative images and quantitative analysis of the cells labelled with 5-bromo-2-deoxyuridine (BrdU) in the central and limbal corneal sections 8 days after pulse treatment with BrdU. The number of BrdU-labelled cells was separately counted in the epithelium (Epi) and stroma. (b) Representative images and quantitation of p63<sup>+</sup> cells. Original magnification ×200. Data are presented as the mean ± SD, and a dot represents a single animal. <span class="nowrap"><svg height="13.9365pt" id="M13" style="vertical-align:-3.834pt" version="1.1" viewbox="-0.0498162
