We borrowed a wonderful cell block procedure from Windham Community Memorial
Hospital here in CT several years ago. The specimen is collected fresh in
sterile saline or RPMI and then centrifuged to concentrate the cells. Plasma
and then thrombin are added to form a clot. The clot is then fixed in formalin
and processed in our Histology Laboratory. I will send the procedure to anyone
who is interested.

Subject: [Histonet] Cell Block Preparation
I am getting complaints in regard to insufficient cell blocks. We currently
spin, pour off the supernatant, retrieve the sediment and process in lens paper.
Does anyone have a more current technique which renders better cellularity?
Also, do you know which renders a better cell block: a fresh specimen, a
specimen fixed in Cytolyt or a specimen fixed in 10% NBF?
Thanks,
Ann
