EXPANDED AND GENETICALLY MODIFIED POPULATIONS OF HUMAN HEMATOPOIETIC STEM CELLS |
摘要 |
<p>The present invention provides a method for promoting the survival and/or expansion of hematopoietic stem cells in culture, comprising culturing the cells in a culture including an effective amount of a mpl ligand, (particularly thrombopoietin), an flt3 ligand and interleukin 6 (IL6). Also provided is a method for modifying hematopoietic stem cells comprising contacting a gene delivery vehicle comprising a polynucleotide sequence with a population of hematopoietic stem cells cultured in the presence of an effective amount of thrombopoietin and an flt3 ligand. Additionally methods of restoring hematopoietic capability in a subject are claimed.</p> |
