However this study comprehensively examined the effects of polystyrene nanoparticles on the development of zebrafish embryos using single cell RNA sequencing analysis explicitly investigating their effects on erythropoiesis. In vivo experiments were conducted using zebrafish embryos to validate the single cell RNA sequencing analysis. Exposure to polystyrene nanoparticles resulted in a decrease in the proportion of mature erythrocytes due to an increase in immature erythrocytes during the erythrocyte differentiation process. Additionally heme synthesis was impaired leading to a decrease in the proportion of erythrocytes. These findings indicated the toxic effects of polystyrene nanoparticles on hematopoiesis. Overall design: 120 hpf zebrafish embryos were pooled as a control groupwild type and 20 nm polystyrene nanoparticles PS20nm exposed group for single cell RNA sequencing.		pubmed:39846194		Zebra PS	GSM8334032		source name:embryos\|tissue:embryos\|Stage:120 hpf\|treatment:PS20nm exposure\|geo loc name:missing\|collection date:missing	Zebra PS	First the quality and basic statistics of raw sequencing data were checked through FastQC. post the quality control process sequencing data were processed through a Cell Ranger v6.0.0 10X Genomics count pipeline using zebrafish genome GRCz11. The zebrafish genome and transcriptome information were downloaded from the Ensembl FTP server release 104 and the index was constructed by processing with the Cell Ranger mkref pipeline. The cellranger count pipeline produces gene expression matrices containing the unique molecular identifier UMI counts per gene per barcode. Also clusters with expression profiles and information on differential gene expression were generated from the pipeline. Downstream analysis was performed using Seurat version 4.3.0 in R version 4.2.2 to process data produced through 10x genomics. Assembly: GRCz11 Supplementary files format and content: Three types of processed data files are provided: barcode.tsv features.tsv matrix.mtx	embryos		The samples were carefully resuspended in a cold calcium and magnesium free solution containing 0.04% BSA/PBS. Cell counting was performed using the LUNA FX7™ Automated Fluorescence Cell Counter Logos Biosystems with acridine orange AO and propidium iodide PI staining Logos Biosystems catalog number F23001. Following this the cells were processed using the Dead Cells Removal Kit Miltenyi Biotech catalog number 130 090 101 and MS columns Miltenyi Biotech catalog number 130 042 201 in accordance with the manufacturer’s guidelines. Following the guidelines of the 10x Chromium Single Cell 5’ v2 protocol 10x Genomics document number CG000331 Single Cell RNA seq libraries were generated using the 10x Chromium Controller and the Next Gem Single Cell 5’ Reagent v2 kits 10x Genomics PN 1000244. In brief the cell suspension aiming for a recovery of 10 000 cells was combined with the reverse transcription master mix and loaded along with Single Cell 5′ Gel Beads and Partitioning Oil into a Single Cell K Chip 10x Genomics PN 1000286 to create single cell Gel Bead in emulsion GEM droplets. Within these GEMs RNA transcripts from single cells were uniquely barcoded and reverse transcribed. post the GEM RT reaction where barcoded full length cDNA was synthesized from mRNA the barcoded cDNA molecules were enriched with PCR. For the preparation of the 5’ Gene Expression Library the amplified cDNA underwent a series of steps including enzymatic fragmentation end repair A tailing adapter ligation and index PCR.		tissue:embryos\|Stage:120 hpf\|treatment:PS20nm exposure	GSM8334032	GSM8334032: Zebra PS; Danio rerio; RNA Seq	GSM8334032 r1	GSM8334032	1	The samples were carefully resuspended in a cold calcium and magnesium free solution containing 0.04% BSA/PBS.
