In early DKD, lower percentages of proliferative PT and PTAQP4+ induced impaired cell repair activity and dysfunction of RAS modulation. CP acted as a central regulator of the induction of ferroptosis in PTAQP4+. Lower percentages of TAL and CD with impaired metabolism function were pathogenic features. SPP1 mediated pathogenic cross-talk in the tubular microenvironment. MC-derived SEMA3C further promoted endothelium-mesenchymal transition in GEC through NRP1 and NRP2 pathway.
