Fig. S1. Histological features between CPP and their corresponding tumors. (A and B)
These histological figures show formalin-fixed, paraffin embedded tissue sections
were stained with Haematoxylin-eosin. Tissues shown are CPP that clonally related
(A) and clonally unrelated (B) to the tumors. CPP show the epithelium is lined with
spindle shaped and the chromatin particles are uniformly small. Adenocarcinoma
show severe irregular branching of glands and hyperchromatic nuclei.
