Simultaneous assessment of TGFB and cell cycle kinetics using IUdR/BrdU infusions in human neoplasms from plastic-embedded tissueMA Miller, SA Bokhari, K Qadir and A Raza Department of Internal Medicine, University of Cincinnati Medical Center, Ohio. We describe an immunohistochemical technique that makes use of two monoclonal antibodies (MAb), one to detect the transforming growth factor B (TGFB) and another that reacts with iodo- and bromodeoxyuridine. The purpose of this technique is to determine the relationship between TGFB expression and the S-phase cells in human tumors. Since both can be distinctly identified in situ from tissue embedded in plastic, in assessment of the geographic orientation of S- phase cells in relation to such factors as TGFB, contiguity to blood vessels, nerve fibers, and macrophages can also be achieved.
