Identification of distinct S species alterations in developmental chick corneas using PCA-LDA computation following XANES spectroscopy. (A) Two-D PCA-LDA scores plot of chick corneas at different developmental days: day 12 (red squares) vs. day 14 (blue circles) vs. day 16 (green triangles). (B) PCA-LDA loadings plot of developing corneas at day 12 vs. day 14 vs. day 16 with LD components as follows: LD1 (red) and LD2 (blue). (C) Corresponding PCA-LDA cluster vectors plot of developmental chick cornea at day 12 vs. day 14 vs. day 16.
