“…Arrows, CD 62p ; Arrowheads, ED 1 In the present study, in spite of the marked increase in MMI in group T, cFn was not increased in group T vs group S. Recently, evidence has been provided that the ECM consists of several ECM proteins, e.g., cFn, type IV collagen, laminin, tenascin, and type I/III collagen, and all are increased in diseased glomeruli. 18,19 However, mesangial ECM is generally assessed by PASM, which stains all the components of the ECM, and the ECM proteins constituting the ECM do not increase in concert. 18,19 This may explain, at least in part, the lack of significance of cFn increase in the face of the significant increase in MMI evaluated by PASM.…”
