This antibody reacts with the antigens of lymphoblastic, Burkitt’s, and follicular lymphomas, and chronic myelocytic leukemia. Also, CD10 detects the antigen of glomerular epithelial cells and the brush border of the proximal tubules. Other non-lymphoid cells that are reactive with CD10 are breast myoepithelial cells, bile canaliculi, neutrophils, a small population of bone marrow cells, fetal small intestine epithelium, and normal fibroblasts."}]}]}
