Cumulative evidence points out to the importance of the bone microenvironment for leukaemic development. Our preliminary results show that bone marrow stem cells, identified by the expression of the intermediate filament protein nestin (Nestin+ cells), provide support and chemoresistance to leukaemic cells. The rationale for these experiments is that leukaemic/Nestin+ cells crosstalk might regulate Nestin+ cells genetic profile to become more supportive elements for leukaemia. Nestin expression level distinguish two different Nestin+ populations, which seem to possess distint characteristics. Therefore, we would like to separately study high-expressing (Nestin high) and low-expressing Nestin cells (Nestin low). From our in vitro results, Nestin+ cells seem to be providing detoxifying tools to leukaemic cells such as antioxidant aminoacids and enzymes. The aim of the project is to identify pathways and genes differentially regulated in Nestin+ high and/or low cells in a leukaemic background.
