Spinal Cord Neuron Isolation: A Density Gradient Procedure to Isolate Neonatal Spinal Cord Neurons for In Vitro Studies
概要
[INSERT FIGURE1 HERE]
Figure 1: Spinal column dissected and spinal cord released from a 3 day-old neonatal mouse. The arrow in (a) points towards the caudal end of the spine, where a needle is inserted to release the spinal cord. A released spinal cord (b) is shown submerged in PBS.

Figure 2: Density gradient, with cells added-on after centrifugation. The layers are outlined and better visualized on the cartoon depiction. The most superficial layer (0) is generally debris from the spinal cord tissue. Layer 1 is rich in oligodendrocytes and astrocytes. Layers 2 and 3 contain the majority of neurons. While layer 3 contains neurons with the highest purity, some supporting cells (i.e., astrocytes and oligodendrocytes) are found in layer 2. The pellet at the bottom mainly contains microglial cells.
