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. Here, CD101 is linked to gastric cancer.
