title: [Effect of extract components from Plastrum testudinis and their combination component on proliferation of rat mesenchymal stem cell in vitro].
abstract: OBJECTIVE
  To observe the effect of extract components from Plastrum Testudinis and their combination component on the proliferaiton of mesenchymal stem cell (MSC) to screen out the effective components.
  
  
  METHODS
  Mesenchymal stem cells were dissociated from bone marrow of rat and were marked by Brdu, and the expression of CD44, CD54 and double label of Brdu and CD44 extract components (A to approximately J) with different concentration (2 microl, 5 microl,10 microl,20 microl)added to cultured MSC. The cell viability was tested by MTT.
  
  
  RESULTS
  Cell viability in component A, B, H, I with 20 microl, C, F with 10 microl and J with 5 microl concentration group increased compared with that in control group (P < 0.05) and cell viability in compponent E with 2 microl to approximately 20 microl concentration groups decreased compared with that in control group (P < 0.05). Cell viability in component D and G with 2 microl to approximately 20 microl concentration groups was similar to that in control group. Cell viability in combination component with J component increased, but cell viability in combination component with E component decrased.
  
  
  CONCLUSIONS
  All compoents A, B,C,F, H, I and J can improve proliferation of MSC. Anong them, component J and its combination are the best. Component E and its combination can inhibit proliferation. But component D and G have no effect on proliferation of MSC.
