Popis: CD34 cells in the interstitial infiltrates in glomerulonephritis (GN) could be the turn - ing point between regenerative processes and interstitial fibrosis. The aim of our study was to assess the presence of CD34+ cells in the interstitial infiltrates in GN. A cross-sectional study of 33 patients with glomerulonephritis, mean age: 43.3 ±11.31 years, 20 male and 13 female, was conducted. Conventional stains, as well as immunohistochemistry for the CD34 antigen were employed on kidney biopsies. Strength of immunohistochemical reaction was assessed semi-quantitatively. Regarding the percentage of cases with CD34+ cells in the interstitial infiltrates out of 33 patients: cells of interstitial infiltrates were 27.3% positive. The percentage of cases showing CD34+ cells at the level of interstitial infiltrates was: 44.4% in FSGS, 14.3% in membranoproliferative GN, 28.6% in membranous nephropathy, 20% in mesangial proliferative GN, 0% in minimal change disease, and 50% in crescentic GN. With the exception of minimal change disease, CD34+ cells were found in the in - terstitial infiltrates in all histopathological forms of GN. Some of these cells were spin - dle-shaped fibroblast-like cells. As inflammation in the tubulointerstitial compart - ment either resolves or proceeds to fibrosis, aims at reversing this process will benefit from analyses of the interstitial infiltrates harboring CD34+ cells.
