(a) The majority of olfactory neurons die within 48 hours in culture when untreated (control). Cells treated with transcriptional inhibitor, actinomycin D (80 ng/ml) or translational inhibitor, cycloheximide (3 µM) remain alive in culture significantly longer in comparison to no treatment (* p<.05; **p<.01; ***p<.001; N=4). (b) Images of GFP signal produced from live OSNs in 48 hour cultures of from left to right, untreated, actinomycin D, and cycloheximide treated cultures.
