Re: Capillary density in Skeletal Muscle

From:Philip Oshel (by way of histonet)

There's another way to do this: corrosion-casting. The blood vessels
are filled with a resin such as methacrylate, and the tissue digested
away. Capillaries show up nicely (even the nuclei of the endothethial
cells lining the vessels can be located), and vessel densities are
easily determined, as well as other properties.

  Visualization is usually done in a SEM, but if colored resin is
used, it can be embedded in a second resin and the whole thing

There are many papers on this method, but Fred Hossler (East
Tennesse?) is a good name on which to do a search.
