72833	SRR23210472	SRX19158411	SRS16570832	SRP418915	PRJNA927004	Differential Nodal level promotes mesendoderm cell fate segregation mediated by chromatin organization	GSE223636	Other	Purpose: To investigate the mechanism of prechordal plate and anterior endoderm separation . Methods: Nodal injected explants injected with 10pg ndr2 mRNA constructed from lft1 mutants and ndr1 morphants were harvested at xxxhpf. Libraries were prepared using Chromium Controller and Chromium Single Cell three primeLibrary & Gel Bead Kit v3 10x Genomics PN 1000075 according to the manufacturer's protocol for 10000 cells recovery. For single cell multiomics zebrafish embryos at 6 hpf were harvested. Libraries were prepared using Chromium Next GEM Single Cell Multiome ATAC + Gene Expression Reagent Bundle 10x Genomics 4 rxns PN 1000285 according to the manufacturer's protocol for 10000 cells recovery. Results: A total of 10 614 single cell transcriptomes and 4 335 multiomics were collected post stringent quality control measures. Conclusions: A slight bias in Nodal signaling promotes a differential chromatin structure between prechordal plate and endoderm which drives a differential expression of those key regulators such as gsc and ripply1 in these two cell lineages and further regulates mesendoderm cell fate separation. Overall design: zebrafish Nodal explants constructed from lft1 mutants and ndr1 morphants were harvested at 6hpf for scRNA seq. Zebrafish embryos were harvested at 6hpf for single cell multiomics.				zebrafish embryo multiomics expression	GSM6969677		source name:zebrafish cells\|strain:AB\|tissue:embryonic cells\|age:6hpf	zebrafish embryo multiomics expression	Illumina sequencing reads were aligned to the zebrafish mRNA reference genome GRCz11 using the 10x Genomics CellRanger pipeline version 6.1.2 and cellranger arc version 2.0.0 with default parameters. Assembly: GRCz11 Supplementary files format and content: tar archivr or gzip compressed files included filtered gene bc matrices and ATAC fragments post running CellRanger or cellranger arc pipeline. Library strategy: scMultiome GEX	zebrafish cells	10pg of ndr2 mRNA was injected to one cell of embryonic animal pole at xxx cell stage. All embryos were incubated in 0.3x Danieau buffer until 1k stage then were transferred to Dulbecco's Modified Eagle Medium. Animal pole explants corresponding roughly to half of the blastula were incubated to 6hpf corresponding to embryonic developmental stage.
