RARB and cancer: Unlike for NR2F1, which was almost exclusively expressed in CAFs, for the other dormancy-related genes: TGFB1 was predominantly expressed by myeloid cells followed by endothelial cells and lymphocytes, SOX9 was predominantly expressed in cancer (epithelial) cells followed by normal (myo)epithelial cells, and RARB was expressed weakly in normal (myo)epithelial cells, CAFs and perivascular-like cells (PVL) (Figure 6A right).
