oligo swing-small

Title: Oligodendrocyte

Description: An oligodendrocyte (blue) extends to form myelin sheaths (green) to encase Purkinje cell axons (red) in the developing rat cerebellum.  The image shows a projected confocal z-stack from a 250µm cerebellar slice where cellular elements were visualized using immunohistochemistry. Olig2 (an oligodendrocyte specific transcription factor) demarcates the oligodendrocyte nucleus shown in blue, myelin basic protein expression in the oligodendrocyte is shown in green, and neurofilaments within Purkinje cell axons are shown in red.

Submitted by: Dr Janelle Pakan, Post-Doctoral Fellow, UCC, Dept of Anatomy and Neuroscience, Dr. Kieran McDermott Laboratory, Ireland.
