Fig. 1: Clonal selection sites and genetic profiling of organoids derived from gastric cancer tissue.

A Intestinal- and diffuse-type gastric cancer specimens marked with regions selected for clonal sampling. B, C Immunohistochemical experiments performed on organoids derived from each clonal sample of gastric cancer specimens, GC141 and GC143, including H&E staining. Scale bars: B 200 μm, C 100 μm.
