title: [Effect of human bone morphogenetic protein 2, 3, 6, and 12 on osteosarcoma cell line UMR106].
abstract: OBJECTIVE
  To investigate the effect of human bone morphogenetic protein (hBMPs) 2/3/6 and 12 on osteosarcoma cell UMR106.
  
  
  METHODS
  Adenovirus-BMP2/3/6 and 12 (AdBMP2/3/6 and12) were used to treat the cell line. Their proliferation, apoptosis, and transmigration were detected by Trypan blue exclusion test, TdT-mediated biotinylated-dUTP nick end labeling (TUNEL), acridine orange-ethidium bromide (AO/EB) double fluorescent dye staining, and transwell-room test, respectively. The alkaline phosphatase (ALP) activity was detected to reflect the differentiation of tumors.
  
  
  RESULTS
  Compared with the control groups, the cell survival rate of the experimental groups treated with AdBMP2/3/6 and 12 showed a significant time-dependent decrease (P<0.01). The apoptosis indexes were increased significantly (P<0.01) and the results from TUNEL and AO/EB method were consistent. The cell numbers of transmembrane significantly decreased at 24,48, and 72 h (P<0.01). AdBMP2/3/6 and 12 treatment enhanced the activity of ALP activity from day 3 and this effect might still be observed up to day 9 of the treatment (P<0.01).
  
  
  CONCLUSIONS
  hBMPs2/3/6 and 12 can inhibit the proliferation and transmigration, and induce their apoptosis and differentiation in osteosarcoma cell line UMR106.
