In addition, we also found that CD93 expression was positively related to almost all immune-related genes, which are known to promote the growth of tumor cells and tumor angiogenesis as well as contribute to tumor metastasis (Li et al., 2021; Schaafsma et al., 2021) in nearly all cancers, which further demonstrated the importance of CD93 in the process of immune regulation. Here, CD93 is linked to cancer.
