Abstract
AIM
To develop conditionally immortalized gastric mucosal cell lines that show distinct types of cell differentiation from transgenic mice harboring temperature-sensitive simian virus 40 (tsSV40) large T antigen.
METHODS
Gastric mucosal cells from the transgenic mice were cultured at a permissive temperature (33 degrees C), and proliferative cells were then cloned by colony formation.
RESULTS
Eight gastric cell lines showed epithelial-like morphology and grew at 33 degrees C. Three different types of the cell lines have been established: (1) MGE12-1, MGE3-2, and MGE509 cells expressing mRNAs for pit cell markers (gastric mucin and cathepsin E); (2) MGE02, MGE503, and MGE511 cells expressing mRNAs for pit and zymogenic (pepsinogen F) cell markers, and (3) MGE507 and MGE727 cells expressing mRNAs for pit, zymogenic, and parietal (H,K-ATPase alpha-subunit) cell markers. Moreover, the TaqMan assay showed that mRNA levels of mucin, H,K-ATPase alpha-subunit, and pepsinogen F were influenced by nonpermissive temperature (39 degrees C) in MGE503 and MGE727 cells.
CONCLUSION
These gastric epithelial cell lines seem to reflect different stages of development of gastric mucosal cells.
