Bar chart of the number of E18 nodose ganglion neurons surviving 24 and 48 h after injection with either an empty pcDNAIII plasmid (vector) or the super-repressor IκB-α plasmid (IκB) expressed as a percentage of the number of injected neurons. The data from neurons grown separately with 50 ng/ml CNTF, 50 ng/ml CT-1, 50 ng/ml LIF, and 10 ng/ml BDNF are shown. The means and SEM of the results of five to ten separate experiments for each factor are shown.
