title: [Isolation and characterization of human placenta derived adherent cells and their hematopoietic growth factor expression].
abstract: OBJECTIVE
  To isolate and culture human placenta derived adherent cells (hPDAC) and assay their hematopoietic growth factor expression.
  
  
  METHODS
  By enzyme digestion, hPDAC were isolated from human placenta tissue and cultured, and their biological characteristics were studied. The hematopoietic growth factor (HGF) mRNA expression of hPDAC was assayed by RT-PCR.
  
  
  RESULTS
  hPDAC was successfully isolated from human placenta tissue, which was further confirmed as mesenchymal stem cell-like cells. HGF including SCF, FL, G-CSF, GM-CSF, M-CSF and IL-6 were expressed in hPDAC.
  
  
  CONCLUSIONS
  hPDAC could be used as feeder layer for umbilical cord blood CD(34)(+) cells ex vivo expansion.
