These aggregates resemble tertiary lymphoid structures (TLS) described in glioblastomas and other cancer types.[60, 61, 62] TLSs facilitate the invasion of immune cells into tumor sites and have therefore attracted significant attention for therapeutic manipulation as a means of improving anticancer immunity and favorable treatment response in patients.[60, 61, 62] As LEC‐like cells co‐localize with CD45+ aggregates, VEGF‐C from LEC‐like cells may drive lymph angiogenesis and facilitate immune cell circulation.[63]. Here, VEGFC is linked to cancer.
