Dissociating and Culturing Neurons from Hippocampal Tissue Samples

Samenvatting

This video demonstrates the dissociation and culture of hippocampal neurons from hippocampal tissue samples using enzymatic and mechanical dissociations. The treatment with Ara-C inhibits the growth of non-neuronal cells, facilitating the selective growth of hippocampal neurons.

Protocol

All procedures involving sample collection have been performed in accordance with the institute's IRB guidelines.

1. Dissection, Dissociation, and Culture of Hippocampal Neurons from Pregnant Mouse/Rat

1. Dissection and dissociation of hippocampal neurons for culture
   1. Thaw protease enzyme solution (3 mg/mL protease 23 in Slice dissection solution, SLDS, Table 1) and pre-warm plating media (Table 2) at 37 °C.
   2. Dissect the hippocampus and rinse with SLDS.
      NOTE: Four hippocampi provide enough cells for one 2....
