There are also GEPNET cell lines derived from transgenic murine rodents, e.g. STC-1 (intestinal NET from SV40-expressing transgenic mouse), βTC and MIN6 (insulinomas from SV40-expressing transgenic mouse), RIN and INS-1 (X-ray induced insulinomas from NEDH rat) (Gazdar et al. 1980, Rindi et al. 1990, Efrat et al. 1991, Asfari et al. 1992, Ishihara et al. 1993). Here, STC1 is linked to pancreatic insulinoma.
