The analysis of CAV1 expression in the single-cell atlas of human breast cancers [40] revealed that CAV1 is highly expressed in stromal cells in the order of endothelial cells, perivascular-like (PVL) cells, and CAFs while weakly expressed in malignant cells and barely expressed at all in immune cells, S5 Fig in S1 File. The gene discussed is CAV1; the disease is breast cancer.
