For mouse phenotyping blood and femurs were collected from animals of different genotypes following standard procedure and processed as previously described16 (link). For flow analysis, samples were stained with Gr1-PE (Miltenyi Biotec, UK),CD11b (Mac1)-FITC (Becton Dickinson), CD71-PE (Becton Dickinson), Ter119-Fitc (Becton Dickinson). For analysis of progenitors population BM cells were lysed with Red Blood Cell buffer (NH4,Cl) and then enriched with the EasySep Hematopoietic Progenitor Cell Isolation Kit (StemCell technologies, UK) followed by staining with following antibodies Sca1-PB , c-KIT-Acy7, CD34-FITC, Flk2-PeCy5, Cd16/32-PE, CD150-PeCy7, CD48-APC.
