Proliferation In Vitro

Previous studies using the in vitro diffusion chamber (Marbrook) have shown that bone marrow grown in this system will undergo limited stem cell replication and differentiation to mature granulocytes and mononuclear phagocytes. A series of studies with modified culture systems was initiated to improve cell production and committed stem cell (CFU-C) proliferation in vitro. Introduction of a continuous-flow system and a migration technique providing means of egress for mature neutrophils resulted in substantially improved performance. CFU-C were found to be capable of migration through a 3-mu pore membrane. These studies indicated that membrane surface area, culture medium circulation, and mature cell egress were among the conditions that could be optimized for maximum hematopoietic cell proliferation in suspension culture. The present observations also suggested that large- scale in vitro growth of mammalian bone marrow may be feasible.

Differentiation Potential

Retroviruses can induce hematopoietic disease via insertional mutagenesis of cancer genes and provide valuable molecular tags for cancer gene discovery. Here we show that insertional mutagenesis can also identify genes that promote the immortalization of hematopoietic cells, which normally have only limited self-renewal. Transduction of mouse bone marrow cells with replication-incompetent murine stem cell virus (MSCV) expressing only neo, followed by serial passage in liquid culture containing stem cell factor (SCF) and interleukin-3 (IL-3), produced immortalized immature myeloid cell lines with neutrophil and macrophage differentiation potential in about 50% of the infected cultures. More than half of the lines have MSCV insertions at Evi1 or Prdm16. These loci encode transcription factor homologs and are validated human myeloid leukemia genes. Integrations are located in intron 1 or 2, where they promote expression of truncated proteins lacking the PRDI-BF1-RIZ1 homologous (PR) domain, similar to what is observed in human leukemias with EVI1 or PRDM16 mutations. Evi1 overexpression alone appears sufficient to immortalize immature myeloid cells and does not seem to require any other cooperating mutations. Genes identified by insertional mutagenesis by their nature could also be involved in immortalization of leukemic stem cells, and thus represent attractive drug targets for treating cancer.
