Project description:To explore the evolution of different cell types across species, we compared transcriptomes between different cell types between two echinoderm species, P. miniata and S. purpuratus. snRNA-seq was used to analyze to characterize diffente cell states. For each species, the time points were integrated into a common atlas and annotated. The fully processed and annotated P. miniata and S. purpuratus atlases are available as supplementary files.
