LGALS1 and pancreatic neoplasm: When all the tumor was analyzed by immunohistochemical staining, we found that tumors of group CFPAC-1 + hCaPSC contained higher levels of Galectin-1 in the PSCs around the CFPAC-1 pancreatic tumor cells than that of group CFPAC-1 + hNPSC (Figure 6d-f), and almost no Galectin-1 staining was observed in the tumors of control group.
