(A) 2–3-month-old mice were treated with tamoxifen and sacrificed 48h later. Single GFP+ and LacZ+ cells appeared in the isthmus of gastric glands in the corpus (arrows). (B) (Left) Characteristic TFF2 antibody staining in the corpus; TFF2-CreERT2 corpus without tamoxifen induction; LacZ staining of TFF2-CreERT2 mice after tamoxifen pulse (scheme on the bottom) showed increasing numbers of LacZ+ cells populating the gastric corpus glands.
