From: The CA19-9 and Sialyl-TRA Antigens Define Separate Subpopulations of Pancreatic Cancer Cells
Staining and morphologies in xenografts. (A) The cell-line xenograft cores showed various amounts of each antigen. The three cores from each cell line are presented in groups. (B) Each PDX xenograft expressed either primarily CA19-9 or primarily sTRA. Each model had 2–6 cores on the TMA. (C,D) Selected images from the cell-line (C) and PDX (D) xenografts are presented. In the overlaid images at the left of each pair, CA19-9 is orange, sTRA is cyan, and the overlapping signal is green.
