AbstractThe genes controlling self renewal in the haemopoietic system are still unknown. Using retroviral insertional mutagenesis we have established multipotent haemopoietic stem cell lines (FDCP-mix) that possess an increased self renewal capacity in vitro. To identify genes involved in the regulation of self renewal, proviral integration sites were cloned from FDCP-mix cells and used as probes to screen independently isolated FDCP-mix cell lines for a common proviral insertion site. So far, two common integration sites have been identified, A25 and M4. A25 is rearranged in 50% of the FDCP-mix cell lines and M4 in 10%. Genes located at or near these sites are likely candidates for the control of self renewal of haemopoietic stem cells.
