Even after 22 hours, the slides appeared to have few cells, and the cells present were not well attached.  It is my theory that 1 of two things are happening: (1) The poly-L lysine slides are not providing strong support for the cells and they are not adhering; or (2) the cells are not getting enough nutrients.  The second hypothesis is easier to test, so I am going to try that.  If I can recover these cells with media, that will, I think, prove my point.  Otherwise, I'll have to repeat the experiment.  If I do that, I'd recommend:

Even after 22 hours, the slides appeared to have few cells, and the cells present were not well attached. It is my theory that 1 of two things are happening: (1) The poly-L lysine slides are not providing strong support for the cells and they are not adhering; or (2) the cells are not getting enough nutrients. The second hypothesis is easier to test, so I am going to try that. If I can recover these cells with media, that will, I think, prove my point. Otherwise, I'll have to repeat the experiment. If I do that, I'd recommend:

  • Trypsin (1 mL)
  • Add DMEM to get to ~1 000 000 cells/mL, then add 100 uL to center of the slide
  • Wait 1-3 hours for basic adherence, then add 3 mL DMEM to promote more growth.


10. Added 3 mL DMEM to each culture dish (22 hours)

Media Addition Results[edit]

There was no improvement in the appearance of the slides at 3 hours post-media introduction, nor 6 hours post-media introduction. I didn't even bother to take pictures, the cells just looked dead. I think that they grew too long with only 100 uL media.
