Recognition of specific targets by cultured dorsal root ganglion neurons. 1987

L Baizer, and M C Fishman

We have assessed the effects of different target cell populations on axonally transported proteins by the use of compartmental cell culture systems that separate the soma from the growing axons of rat sensory neurons. The labeling of 3 rapidly transported proteins diminishes when the growing axon contacts spinal cord cells (which are normal in vivo targets), and remains unaffected by contact with fibroblasts or heart cells. Medium conditioned by spinal cord cells does not exert this effect. Thus, specific classes of cells may be distinguished as target tissue by sensory neurons in vitro. Such recognition is accompanied by specific molecular changes in axonally transported proteins.

D005347	Fibroblasts	Connective tissue cells which secrete an extracellular matrix rich in collagen and other macromolecules.	Fibroblast
D005727	Ganglia, Spinal	Sensory ganglia located on the dorsal spinal roots within the vertebral column. The spinal ganglion cells are pseudounipolar. The single primary branch bifurcates sending a peripheral process to carry sensory information from the periphery and a central branch which relays that information to the spinal cord or brain.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
