Transgenic mice used as models for human pathologies originating from stem cells

摘要

The invention relates to non-human transgenic mammals which reproduce human pathologies originating from stem cells, e.g. chromosomal anomalies associated with chronic myeloid leukaemia, B-cell lineage acute lymphoblastic leukaemia, T-cell lineage acute lymphoblastic leukaemia or the migration of hematopoietic or embryonic stem cells. The invention makes use of the expression of genes which, in humans, are involved in said pathology, employing a promoter which directs the expression of a transgene in Sca-1+ cells. The aforementioned transgenic animals provide a model which allows the above-mentioned diseases to be studied and compounds for treating and/or preventing said diseases to be evaluated.
