Interaction of graphene oxide nanoparcticles with human mesenchymal stem cells

<p>Interaction of graphene oxide nanoparcticles with human mesenchymal stem cells visualized by phase-contrast microscopy (Cell-IQ system) over 24 hours. Two concentrations of nanoparticles were used: 5 &micro;g/mL and 25 &micro;g/mL. Four types of particles were used:</p> <table> <tbody> <tr> <td> <p><strong>Notation</strong></p> </td> <td> <p><strong>Diameter (nm)</strong></p> </td> <td> <p><strong>Coating</strong></p> </td> </tr> <tr> <td> <p>P-GOs</p> </td> <td> <p>184 &plusmn; 73</p> </td> <td> <p>Linear PEG</p> </td> </tr> <tr> <td> <p>bP-GOs</p> </td> <td> <p>287 &plusmn; 52</p> </td> <td> <p>Branched PEG</p> </td> </tr> <tr> <td> <p>P-GOb</p> </td> <td> <p>569 &plusmn; 14</p> </td> <td> <p>Linear PEG</p> </td> </tr> <tr> <td> <p>bP-GOb</p> </td> <td> <p>1376 &plusmn; 48</p> </td> <td> <p>Branched PEG</p> </td> </tr> </tbody> </table> <p>File names in the archive are as follows:</p> <p>Video S1: Visualization of incubation of cells with P-GOs nanoparticles (5 &mu;g/mL)<br> Video S2: Visualization of incubation of cells with P-GOs nanoparticles (25 &mu;g/mL)<br> Video S3: Visualization of incubation of cells with bP-GOs nanoparticles (5 &mu;g/mL)<br> Video S4: Visualization of incubation of cells with bP-GOs nanoparticles (25 &mu;g/mL)<br> Video S5: Visualization of incubation of cells with P-GOb nanoparticles (5 &mu;g/mL)<br> Video S6: Visualization of incubation of cells with P-GOb nanoparticles (25 &mu;g/mL)<br> Video S7: Visualization of incubation of cells with bP-GOb nanoparticles (5 &mu;g/mL)<br> Video S8: Visualization of incubation of cells with bP-GOb nanoparticles (25 &mu;g/mL)<br> Video S9: Visualization of incubation of cells in the control group (without GO nanoparticles)</p>
