Nat Rev Neurosci. J Immunol. Since we do not see any overt neuron loss in the slices at least up to 28 DIVwe were interested in understanding some of the changes that occur at synapses prior to neuron loss. J Neuroimmunol. Languages Add links.

  • Altmetric – Organotypic brain slice cultures A review
  • Preparation of organotypic hippocampal slice cultures interface method.

  • The slice preparation or brain slice is a laboratory technique in electrophysiology that allows the study of a synapse or neural circuit in isolation from the rest of. Thus, organotypic brain slice cultures have proven to be very useful in investigating cellular and molecular processes of the brain in vitro.

    De Simoni A(1), Yu LM. Author information.
    This method has been already validated in human tissue, in vivo and in organotypic cultures [ 20 — 22 ].

    We have previously characterised organotypic brain slice cultures prepared from 3xTg-AD mice in comparison to brain from aged in vivo 3xTg-AD mice However, they likely still have advantages over dissociated co-culture primary cell culture for this purpose, and the lack of a blood-brain-barrier has advantages for drug screening.

    These data suggest that potential therapeutic agents can be sensitively examined in organotypic brain slice culture models.

We have previously described the methods and results obtained using LDH assays Croft et al. C Two hemi-brains are kept in oxygenated dissection buffer throughout the procedure; one hemi-brain is stored whilst the other is processed.

    Brains from pups were bisected into hemi-brains by a single cut along the midline.

    Genotyping was performed regularly every generation on our colony to ensure that transgene expression was consistent since we are aware that this can be a problem with transgenic lines. Proteins were prepared according to our previous publication [ 21 ]. Pups are decapitated using Mayo scissors and death confirmed. The removal of the brain tissue from the body removes the mechanical effects of heartbeat and respirationwhich allows for extended intracellular recording.

    Control corresponds to the culture medium of organotypic slices without treatment.

    This model was simplified by growing organotypic brain slices on a membrane surface [17].

    1 reference. stated in · Europe PubMed. The researchers performed whole-cell recordings in organotypic hippocampal slice cultures dissected from postnatal day 7 (P7) rats.
    We agree that littermate controls are more desirable, but we were unable to do this for the reported work.

    We describe our work previously showing that slice cultures prepared from 3xTg-AD mice recapitulate important molecular and cellular features of in vivo disease development and the human disease phenotype.

    Are sufficient details provided to allow replication of the method development and its use by others? The methods of creating and maintaining the slice cultures are clearly described in detail allowing for future replication by other groups.

    Finally, the artificial composition of the bathing solution means that the presence and relative concentrations of the necessary compounds may not be present. To mimic or prevent BBB disassembly, we used diverse pro- or anti-angiogenic treatments.

    Spreadsheet data files may not format correctly if your computer is using different default delimiters symbols used to separate values into separate cells - a spreadsheet created in one region is sometimes misinterpreted by computers in other regions. No change in synaptic APP We thank the reviewers for their balanced and critical reviews.

    This was out-with the scope of the current publication, but we have added details of these papers to our manuscript to direct the reader to these complementary publications.
