CDH1 and diabetes mellitus: This resulting metabolic histology revealed ten different renal cell types in both control and diabetic kidneys; glomerular, vascular, cortical proximal tubular segments (PT_S1/S2), the outer medullar outer stripe proximal tubular segment (PT_S3), distal tubular (DT), inner medulla (IM), CDH1 negative cells in the inner stripe of the outer medulla (ISOM_CDH1-), and collecting ducts and loop of Henle cells in the outer stripe of the outer medulla (OSOM_CDLH), in the inner stripe of the outer medulla (ISOM_CDLH) and in the cortex (C_CDLH) (Fig. 2B,C).
