Transmitter responsiveness in two newly isolated clones of neuroblastoma X glioma hybrid.
Mouse neuroblastoma clone N1E-115 cells and rat glioma clone C6 cells were hybridized and two new clones were isolated. One clone, designated NG115-301, possessed weak electric excitability to an applied current pulse, while another clone, NG115-401, generated an action potential in response to the pulse. The former clone responded to serotonin and catecholamines with slow hyperpolarizations, while the latter clone responded to catecholamines with transient depolarizations. Both clones did not respond to acetylcholine. These types of responses have not been reported in any available clones. These clones may enrich the repertoire of cell clones useful for the characterization of transmitter reception mechanisms in the nervous system.
