SLC40A1 and cancer: Predominantly residing in PTs (Fig. 4c), Macro06 synchronously behaved as M2-like TAMs (e.g., LYVE1, SEPP1, MRC1, FOLR2)39, as well as perivascular TAMs (e.g., MRC1, VCAM1, SLC40A1) (Fig. 4f, g), which probably facilitated vascular development and cancer cell intravasation (Fig. 4c–g)32,40.
