Correlation between CA19‐9 production <i>in vitro</i> and histological grades of differentiation <i>in vivo</i> in clones isolated from a human pancreatic cancer cell line (SUIT‐2)

Abstract excerpt

The production of carcino-embryonic antigen (CEA) and carbohydrate antigen 19-9 (CA19-9) were investigated in 28 clones isolated from a human pancreatic cancer cell line (SUIT-2) and related to in vitro morphology of the clones and in vivo tumorigenicity. Clones of fusiform and polygonal cells could be morphologically distinguished in confluent cultures. There was no significant difference in CEA production...
