Figure 1

Immunohistochemical staining showed tubulointerstitial CD34 loss with the accumulation of PDGFRβ and A1AR in patients with GML and DN. (a–c) The expression of CD34, PDGFRβ, and A1AR in GML and DN patients was measured by semiquantitative analysis of immunohistochemical staining. (d) The costaining of CD34 and PDGFRβ in DN patients. Data were presented as the (~10 per group). , #. Original . Bar width: 50 μm. GML: glomerular minor lesion; DN: diabetic nephropathy.
