Coverslip at bottom.
Space of approx 11 um with media.
collagen matrix above.

The image above is a single optical section through the collagen matrix.
The image below is a XZ section along the yellow line in the image above.

Cells were imaged with reflection at 488 nm and a red dye excited at 568 nm.

A good way to see both reflection and the tracer dye would be to stain the actin for excitation at 633 nm (e.g. Cy5 or Alexa 633).
