If activity directly instructs OPCs to differentiate or whether this process underlies a more complex regulation in unclear because it is not known if OPCs with different functions exist. By following lineage formation of individual OPC clones single cell RNA sequencing in vivo calcium imaging and manipulation of neural activity we show that OPCs in the zebrafish spinal cord can be divided into two functional entities. One subgroup forms elaborate process networks and exhibits a high degree of calcium signalling activity but infrequently differentiates despite contact with permissive axons. Instead these OPCs can divide in an activity and calcium dependent manner to produce another subgroup of OPCs which readily differentiates and which shows less elaborate more dynamic processes and less calcium signaling activity. Our data reveal functional diversity within the OPC population in responding to neural activity and show that activity regulates proliferation of a subset of OPCs that is distinct from the cells that will differentiate with implications for myelin development plasticity and repair.

Individual cell fastq files were aligned to the transcriptome with STAR.2.5.1b GRCz11 ENSEMBL94 reference genome. Gene expression for each gene was calculated with Salmon0.9.1 using the reads aligned to the transcriptome for each of the individual cells. Expression matrix was built by combining all cells gene expressions as TPM. QC and clustering with Seurat3 allowed the annotation of 310 individual cells in specific celltypes. The R object .rds consists of a Seurat v.3 object. Cells were clustered with Seurat v.3 and filtered based on the distribution of gene expression and mitochondrial gene expression. The remaining 310 cells were log normalized individually with a scale of factor of 10 000. The shared nearest neighbor SNN graph was constructed on cell to cell distance matrix from top 50 PCs. The SNN graph with resolution 1 was used as an input for the smart local moving SLM algorithm to obtain cell clusters and visualized with t distributed stochastic neighbor embedding t SNE. The object includes in reductions tsne and metadata Celltype the embedding and clustering used in the study.

By following lineage formation of individual OPC clones single cell RNA sequencing in vivo calcium imaging and manipulation of neural activity we show that OPCs in the zebrafish spinal cord can be divided into two functional entities. One subgroup forms elaborate process networks and exhibits a high degree of calcium signalling activity but infrequently differentiates despite contact with permissive axons. Instead these OPCs can divide in an activity and calcium dependent manner to produce another subgroup of OPCs which readily differentiates and which shows less elaborate more dynamic processes and less calcium signaling activity. Our data reveal functional diversity within the OPC population in responding to neural activity and show that activity regulates proliferation of a subset of OPCs that is distinct from the cells that will differentiate with implications for myelin development plasticity and repair. Overall design: Single cell RNA sequencing from zebrafish with genetically labelled Oligodendrocyte Precursor Cells was carried out to reveal the genetic heterogeneity of this population. The transcriptomic data will be supplemented with RNA in situ hybridization and immunofluorescence stainings to validate candidate markers of subopulations and in vivo live cell imaging data to map cell fates.
