resting and proliferating cells in mesangial areas did not stain with anti-ia antibody and extracapillary proliferating cells did not express ia antigen except for occasional cells in anti-gbm crescentic glomerulonephritis , suggesting that ia-bearing cells are not involved in mesangial and most extracapillary proliferations in human glomerulonephritis .
