Ralph,

Thank you so much for your input. Now that I know it has been done and
with your advice I feel I can move forward with more confidence. Thanks
again.

Betsy,

In case you haven't had specific procedural reply's, I'll say yes.  Did
it for several years but back where I can't get at notes and 15 years of
memory loss.  Did VK on my cultures I maintained for project.  Performed
on 8-well tissue culture slides, both glass and plastic and tissue
culture plates of all sizes.  The procedure is basically the same as the
VK you know-it just needs a bit of inginuity. Anything plastic obviously
you can't go through xylenes but that didn't matter as after NFR, washed
in water, got a coverlip on somehow with aqueous media and photographed
right on plate with inverted scope or slide as usual.  Didn't use "the
sun" but a great lamp.  Make sure you have a good positive control to
work up procedure.  I made up my own pos and neg tissue culture controls
for VK as my experiments went forward. Look in PubMed and find van
Griensven M,  Exp Toxiicol Pathol  2002 Jul; 54 (1) 25-9.  Or the
Journal Calci fied Tissue International vol 72, Number 5, May 2003
537-547 "Von Kossa Staining alone is not sufficient to confirm that
mineralization in vitro represents bone formation;   the authors of
which (Bonewald, Harris, Rosser, Dallas)came out of Texas Health
Sciences Center down your way.  There are many other such references in
a PubMed search.  Would that they had published years earlier so I
wouldn't have had so many nights and weekends in the lab.  But my thesis
adviser honestly did not say there would be much glory and stardom, just
lots of hard work.
