Mechanisms of cell death in primary cortical neurons and PC12 cells.

abstract：:Embryonic central nervous system neuroepithelial cells are a transient population of cells that give rise to neuronal and glial progenitors. In the E12-E16 embryonic rat spinal neural tube we have identified neuroepithelial cells as radially oriented cells expressing the GD3 ganglioside as recognized by the monoclonal...
