[Histonet] A question on setting up of organotypic cultures , on the use of heparin in perfusion fluid (non-fixative) and finally , sucrose and ECF
|From:||"Hanna-Mitchell, Ann" |
Good Evening from a very wet and windy Ireland!
I am setting up spinal cord slice cultures .
Does anyone have any particular opinion on the use of the anti-coagulant
heparin in perfusion buffer ( non-fixative)prior to removal of 'wet' tissue
( in my case spinal cord) to be processed for culture. It is used by some
researchers in my Department but in this instance they are pre-perfusing
with 'buffer' prior to perfusing with fixative for other purposes.
As I want to maintain the tissue in as healthy a condition as possible, I
worry that heparin in my protocol might have unwanted effects on it . At
the moment I have stopped using heparin.
As regards sucrose, how does pressure perfusion cause sucrose molecules to
move from the intravascular to the extravascular compartment in the brain?
Lastly,I should really appreciate some advice on the following:
having sliced the spinal cord segment on a tissue chopper (slice thickness:
400Ám),and having separated out single slices , how does one get these
slices onto a millicell insert?
Thank you for reading this . I should very much appreciate any assistance
