| Title |
Streaming stage replicate 1 [NovaSeq] |
| Sample type |
SRA |
| |
|
| Source name |
Streaming cells
|
| Organism |
Dictyostelium discoideum AX4 |
| Characteristics |
developmental stage: Streaming
genotype: WT
|
| Growth protocol |
We cultured te strain at 22 °C shaken in the incubator at 180 rpm in HL5 medium with 300 μg/ml streptomycin.
|
| Extracted molecule |
total RNA |
| Extraction protocol |
Cells were dissociated into single cells from different stages by physical pipetting with PBS + 0.04% BSA. The cell numbers were counted using a microscope.
Cell from each sample were subject to Chromium Single Cell Gene Expression kit V3 (10x Genomics) for library construction according to the manufacturer’s instructions.

| Data processing |
Sequence reads were aligned, quantified by Cell Ranger with default setting except using normalized="none" for aggr function.
Low quality cellsor outliers were filtered out from the data by the following threshold: 200 < total Gene count < 7000, 500 <total UMI count <30000.
Normalization (SCTransform), batch correction (Harmony) and dimension reduction (PCA and UMAP) were conducted in Seurat.
raw_sc_Dicty_3_stage.tsv was generated by removing streaming stage cells from the matrix.
raw_sc_Dicty_3_stage_ds.tsv (used for pseudotime analysis) was generated by downsampling the raw_sc_Dicty_3_stage.tsv.
Genome_build: AX4
Supplementary_files_format_and_content: Matrix of UMI counts per gene for each cell.
Supplementary_files_format_and_content: The information (cell stage, batch…) of each cell barcode in the quantification matrix file.
