Bovine Pulmonary Artery Endothelial Cells
The actin filaments in these fixed bovine pulmonary artery endothelial cells (BPAEC) were labeled with phalloidin conjugated to Alexa Fluor® 647 dye. Phalloidin is a deadly toxin isolated from the “death cap" mushroom that binds specifically at the interface between F-actin subunits. Alexa Fluor® 647 exhibits far-red fluorescence, which has been pseudo-colored magenta in this image. Nuclei were stained with blue-fluorescent DAPI.

- neural stem cells lie in the layer closest to the ventricular space, the ventricular layer
- this layer generates both neuroblasts and glioblasts
Neuroblasts - neurons arise first as neuroblasts and migrate along radial gial, their migration stops at cortical plate. Glioblasts - glia arise later as glioblasts
Both neurons and glia undergo a complex process of growth, differentiation and interaction over a long developmental time period.
