title: [Liposome-mediated gene transfer into bone marrow cells and its in vitro expansion].
abstract: OBJECTIVE
  To explore the efficiency of liposome-mediated gene transfer into bone marrow cells and the stability of its expression.
  
  
  METHODS
  Two marker genes (Neo and Lac Z) mediated by liposome were co-transferred into bone marrow cells. Following G418 screening,the positive cells were enriched and expanded in vitro.
  
  
  RESULTS
  The liposome-mediated gene transfer rate in bone marrow cells was 13.33 +/- 2.68%, and after G418 screening, it was 46.06 +/- 3.47%. The blue colouring rates with X-gal staining of these cells were not significantly different before and after expansion.
  
  
  CONCLUSIONS
  Liposome-mediated gene transfer in bone marrow cells is highly efficient and the expression of the transferred gene is stable.
