One classical marker of principal cells in the mammalian epididymis is the water channel aquaporin 9 (AQP9), we present evidence that cluster 1 cells may encompass apical and narrow cells, rather than principal cells. The next most abundant cluster of cells (cluster 2) is primarily contributed by donors AXH012 and AXH014 and inspection of the DEG list suggests these may arise from ED cells contaminating the caput tissues. The diagnostic marker for the ED is villin (VIL1), which is apparently abundant in the ED epithelium but not seen in the caput epithelium in tissue sections |
