“…Following initial inductions of myelogenous leukaemia employing largely polynuclear aromatic hydrocarbons, 128,129 several transplantable AML rat models 9,130-149 became available (Table 3 and reviewed 150,151 ). Primarily, the Wistar/Furth, 152 L5222 acute rat leukaemia in BDIX 142 and the BNML 9 rat models, all with predictable growth characteristics, 138,153,154 analogous biology to human AML, 142,143,155,156 ease of transplantability with excellent levels of engraftment 9,138 and similar susceptibility to clinical chemotherapeutic regimes employed in human AML 138,157,158 emerged as suitable experimental models. However, in comparative colony-forming (CFU-s) studies, 143,159 it was soon Insertional mutagenesis.…”
