Figure 1. Principal component analysis (PCA) for the human central epithelial cells at 0H and equatorial epithelial cells at 0H and 24H culture. The circles represent the central epithelial cells while the triangles represent the equatorial epithelial cells. The color red represents the 0H culture time point and blue represents the 24H culture time point. Note that two of the 24H equatorial LECs samples (right most triangles) are nearly entirely overlapping. y/o (years old) signifies the age of each donor. Additional details can be found in Appendix 1.
