For cases where multiple spatiotemporally regulatory modules were identified, statistically significantly enriched expression within cell types was also tested. The p-value scale obtained using the hypergeometric distribution is indicated on the top of each panel. (A) Shift of +2. Many clusters display distinct cell type enrichment profiles. (B) Shift of +3. At least two significantly cell type-enriched clusters were identified. (C) Shift of -2. Among many clusters, specific cell-type enrichment was identified in only a single cluster.
