Correspondence of molecular and cellular changes in the olfactory epithelium at 5 days after bulbectomy (OBX). These plots separate gene expression patterns into four quadrants, each representing distinct cell type categories as labeled. A. Transcripts that decreased after OBX tended to be expressed in mature OSNs (upper quadrants). B. Transcripts that increased after OBX tended to be expressed by immature OSNs (right quadrants) or by cell types other than OSNs (lower left quadrant).
