DSL-6A/C1 is a pancreatic ductal cell line derived from the DSL-6 transplantable acinar cell carcinoma. The DSL-6 tumor was established in 1986 from a primary acinar cell carcinoma of the pancreas which developed in a male Lewis rat（DSL-101-79） that was given azaserine intraperitoneally. The cultured DSL-6A/C1 tumor cells initially produced amylase, but production of exocrine enzymes ceased after 1 to 2 weeks in culture. The cell line also lost structural and immunohistochemical acinar cell markers while acquiring duct cell markers during culture and regrafting. The DSL-6A/C1 cell line expresses the ductal marker cystic fibrosis transmembrane regulator （CFTR）.The species was confirmed by Real-Time PCR.
