[Histonet] Embedding bone marrow aspirates

Hello Colleagues,
I'm looking for opinions/experience regarding the following idea:

I am thinking about using Histogel (not pushing this product over
another, just don't know what else to call it!!) to localize the
aspirate to a more confined area, hopefully more consistently on a
single plane, and perhaps improve the "cutability" of the more brittle,
crumbly specimens.
Currently we filter BM aspirates with a piece of lenspaper, scrape the
tissue from the "filter" onto a smaller piece of lenspaper that is then
folded and placed between 2 biopsy pads in a cassette. Then the embedder
has to scrape the processed material into the embedding mold and
hopefully get most of it in the same plane (which he does reasonably

What I would like to do is scrape most of the tissue to the bottom of
the lenspaper filter cone, add histogel and then place the resulting
pellet in a cassette for subsequent processing.

I look forward to reading your knowledgeable replies. 

Have a nice weekend everyone.
