using transplantation of transgenic knock-in JAK2V617F hematopoietic cells into a single irradiated leg, we show development of Polycythemia Vera (PV) from a single anatomical site in immuno-competent mice. Mutant cells colonizing the non-irradiated leg efficiently induce PV. We compared transcriptomic profiles of sorted JAK2V617F HSPC and their reciprocal endogenous WT HSPC in the non-irradiated and irradiated legs from recipient mice transplanted with JAK2V617F hematopoietic cells. Overall design: we assesed the differentially expressed genes between endogenous WT and JAK2V617F sorted HSPC from the non-irradiated leg in order to find new potential therapeutic target for suppression of PV syndrome in this pre-clinical model through specific targeting of JAK2V617F cells.
