TGP 55

Study of exocrine pancreas carcinomas, hormone secretion studies.

Mouse pancreatic small cell anaplastic carcinoma

TGP 55 has been obtained from a small cell anaplastic carcinoma arising in the pancreas of a transgenic Tg(Ela-1SV40E)Bri 18 mouse these mice carry a pseudogene construct composed of a pancreatic-specific elastase-1 promoter linked to the coding region for SV40 T antigen and thereby represent an animal model for pancreatic carcinogenesis. TGP 55 cells are SV40T antigen positive and secrete somatostatin, it is one of a series of cell lines isolated from pancreatic tumours deposited at ECACC. Cells secrete somatostatin and insulin in culture. Adherent clumps of small cells.

DMEM:Ham′s F12 (1:1) + 2mM Glutamine + 10% Foetal Bovine Serum (FBS) (Heat Inactivated).

Split sub-confluent cultures (70-80%) 1:3 i.e. seeding at 3x10,000 cells/cm² using 0.25% trypsin or trypsin/EDTA; 5% CO₂; 37°C.
