ICAM1 and neoplasm: Similarly, we defined four tsNeu subsets based on their expression levels of CD54 and CD101 in the tumor tissues from the orthotopic GC model, as well as from an MNU-induced GC model (Fig. 2D), confirming that CD54 and CD101 can serve as specific cell surface markers to subclassify and isolate tsNeus into four subpopulations.
