To extend these findings to human atherosclerosis, we FACS‐isolated CD45+CD68+ macrophages from human coronary atherosclerotic plaques and matched normal coronary artery samples (n = 20 donors, two plaque samples, and one normal sample per donor) (Figure 2h) (note: the myeloid lineage marker CD45 was used to exclude macrophage‐like VSMCs that express CD68[12]). The gene discussed is PTPRC; the disease is atherosclerosis.
