Principle component and heat maps
PCA revealed that the HDFs, AG13145 and CRL-2617, clustered separately
from the cSCC cell lines, SCC-13 and A431 (Figure 1A). Additionally,
there was greater clustering among cell lines than between treatment and
control (Figure 1B). Heat map analysis demonstrated similar clustering
of treatment and control groups among fibroblast and cSCC cells (Figure
1C).
