Abstract:
In vitro clonogenic assays have been developed and widely used since many years to investigate the proliferation and the differentiation both of pluripotent haemopoietic stem cells (PHSC) and of the different progenitors of blood cell lineages: megakaryocytes (Colony Forming Unit-Mk) granulocyte -macrophage (CFU-GM), erythrocytes (BFU-E/CFU-E). As these techniques have been introduced, they appeared to be very useful to investigate the pathogenic mechanisms of drug induced blood disorders and also for screening compound during preclinical safety study. Because the integrity of the hematopoiesis is also essential to guarantee the immunological function, the application to the toxicology of these clonogenic assays, provides an essential tool for better understanding the in vivo observation (experimental and clinical) by also help in predicting the degree of a possible in vivo haematotoxic in drug treated patients. The review introduces to basic concepts on hematopoiesis and on classical evaluation of a drug haematotoxic phenomenon. It describes the application of each clonogenic tests to assess the specific hematotoxicity action. Moreover it report the most recent studies on standardisation, prevalidation and validation of such assays and critically reviews a model for predicting myelotoxicity by discussing the main aspects referred to the evaluation of the in vivo acute neutropenia by using the in vitro CFU-GM assay
