Immature OSN mRNAs that increased after bulbectomy (red) have an expression pattern distinct from immature OSN mRNAs that decreased after bulbectomy (blue). A. Decreased mRNAs had higher P(sp) and P(in) values in mature OSN categories (mOSN and Shared categories) while increased mRNAs had higher values in Other cell type and immature OSN-specific categories. Error bars, standard deviations. B – D. Examples of the density distributions of the increased and decreased immature OSN transcripts for three measures of cell type expression patterns in the olfactory epithelium. All distribution pairs differed (p = 0.0000 in each case).
