scRNA-seq of coelomocytes in Apostichopus japonicus
four sets of samples including coelomocytes from coelom (CC), water-vascular system (PC), and their evisceration (ECC, EPC) were collected to produce single-cell transcriptome profiles. A total of nineteen clusters were identified based on the mRNA expression profiles of four samples. Furthermore, some evolutionarily conservative cell signatures were adopted to indicate cell types and their individual biological functions of each subpopulation were subsequently assessed.
