Clownfish settled on an anenome
Schematic drawing of cell clusters that comprise germ layers, organs, and tissues of gastrulae and larvae
(A) Gastrula (left side view). (B) Anatomical distribution of each cluster in gastrulae. (C) An early larva, left side view. (D) Anatomical distribution of each cluster in early larvae. Cluster numbers are shown with corresponding germ layers, organs, and tissues. This figure shows that for examples cells of cluster 8 comprise apical plate and cells of cluster 9 comprise coelom, a mesodermal derivative.
UMAP plot for clustering of embryonic cells obtained by single-cell RNA-seq analyses
Based on shared expression profiles of transcription factor genes and cellular signaling molecule genes, constituent cells of starfish embryos and larvae can be categorized into 22 clusters, numbered 0 to 21. Each dot represents each cell.
