Key factors in experimental mouse hematopoietic stem cell transplantation
Languages of publication
The first mouse model of hematopoietic stem cell transplantation (HSCT) was developed more than 50 years ago. HSCT is currently being widely used in a broad range of research areas, which include studies of the engraftment process, the pathogenesis of graft-versus-host disease and possible ways of its treatment and prophylaxis, attempts to use the graft-versus-leukemia/tumor effect in treating hematological and oncological malignancies, cancer vaccine development, induction of transplanted organ tolerance, and gene therapy. However, although this model is widely distributed, many laboratories use different protocols for the procedure. There are a number of papers discussing different HSCT protocols in clinical work, but no articles summarizing mouse laboratory models are available. This review attempts to bring together different details about HSCT in the mouse model, such as the types of transplantation, possible pretreatment regimens and their combinations, methods and sources of graft harvesting and preparation for the transplantation procedure, the influence of graft cell dose and content on the engraftment process, the transplantation method itself, possible complications, symptoms and techniques of their prophylaxis or treatment, as well as follow-up and engraftment assessment. We have also tried to reflect current knowledge of the biology of the engraftment.
