title: [Biocompatibility of p(3HB-co-3HH) and marrow mesenchymal stem cells].
abstract: OBJECTIVE
  To investigate the biocompatibility of p(3HB-co-3HH) and marrow mesenchymal stell cells (MSCs).
  
  
  METHODS
  MSCs were inoculated to p(3HB-co-3HH), and then cultured for 2-4 weeks in vitro and embedded for 2 weeks in vivo. The growth, proliferation, morphology and phenotype properties of MSCs were observed by use of phase contrast microscope, electron microscope, HE staining and staining of type I collagen.
  
  
  RESULTS
  p(3HB-co-3HH) had good compatibility. The inoculated MSCs could be well-distributed, attached well and obtain the phenotype of MSCs in p(3HB-co-3HH). After osteogenic inducer were added, MSCs differentiated to osteoblasts and secreted matrix. Type I collagen was stained positively by immunohistochemical techenique.
  
  
  CONCLUSIONS
  The above results demonstrate that there is satisfactory biocompatibility between p(3HB-co-3HH) and MSCs.
