Synchrotron FTIR microspectrosopic comparison of SC and TA cell populations in human cornea (A). Median spectra for SC (red) and TA (blue) cell populations. B: The difference spectra between the SC and TA cell populations. C: Significance values for Mann-Whitney comparison of SC and TA spectra (p<0.05 below line).
