Small Molecule Protection of Bone Marrow Hematopoietic Stem Cells
Abstract
During the above project period we have demonstrated the following progress on Aims 1 and 2, and have keyed the following results to specific major tasks under each Aim: 1. mitotic expansion of human mobilized peripheral blood CD34 positive hematopoietic stem cells (HSCs) in culture in defined medium supplemented with hematopoietic growth factors and small molecule inhibitors of differentiation; 2. suppression of differentiation of CD34 positive CD38 negative CD90 positive during mitotic expansion in culture by addition of the small molecule inhibitors SR-1 or UM-171, alone or in concert; 3. dose-dependent killing of CD34 positive CD38 negative CD90 positive HSCs by the addition of formaldehyde; 4. development of sensitive and specific mass spec assays for DNA adducts and DNA-protein crosslinks (DPCs) generated by formaldehyde in human cells.
