title: [Application of green fluorescent protein gene in study of adipocyte differentiation].
abstract: OBJECTIVE
  To establish a model for dynamic detection of adipocyte differentiation in vivo by green fluorescent protein (GFP).
  
  
  METHODS
  The promoter of peroxisome proliferators-activated receptor gamma 2 (PPARgamma2) gene was amplified by PCR from the genomic DNA of human preadipocytes, inserted into the eukaryotic expression vector pEGFP-1 and transferred into NIH3T3 fibroblasts and preadipocytes which were induced to differentiate into adipocyte.
  
  
  RESULTS
  Upon induction with insulin, dexamethasone and 3-isobutyl-1-methyl xanthine, the transformed human preadipocytes differentiated into mature adipocytes and expressed GFP, but NIH3T3 fibroblasts could not differentiate into adipocytes or express GFP.
  
  
  CONCLUSIONS
  Transformation of human preadipocytes with the recombinant of PPARgamma2 promoter with GFP gene can be employed to dynamically detect the differentiation of adipocytes in vivo.
