BACKGROUND Hematopoietic stem cell (HSC) regulation is highly dependent on interactions with the marrow microenvironment, of which osteogenic cells play a crucial role. While evidence is accumulating for an important role of intrinsic miR-17 in regulating HSCs and HPCs, whether miR-17 signaling pathways are also necessary in the cell-extrinsic control of(More)
We have recently found that miR-17 is necessary in the cell-extrinsic control of cord blood (CB) CD34+ cell function. Here, we demonstrated that the proper level of miR-17 is also necessary in the cell-intrinsic control of the hematopoietic properties of CB CD34+ cells. The miR-17 overexpression and knockdown models were created using primary CB CD34+ cells(More)
